Wow, this is enlightening! On and off I've been involved and interested in photography since the late 1970's and had no freakin' idea about infinity reference points for any given focal length. Thank you!
Fantastic again. I did not realise I did not know what Infinity was. Not sure I know it even now. Poor Harry - was Marcus throwing the water???? Made me laugh. Little Sheanna was adorable.
Great show - very informative and the production values are excellent as always - kudos to all. Harry deserves a medal for his clothing presentation..... Cheers, all.
Hi Ruth and team another great show i loved the part when Marcus described infinity in detail that was a massive help. Look forward to the next show very best wishes.
A top quality show as usual, ruined only by the appearance of Harry's legs again. The article on clothing was very useful. I now understand the infinity focus, what a great explanation. Keep up the excellent work
Another thoroughly informative and educational instalment of Photography Online. On a recent trip, 4 of us subscribed, the other 5 seemed very interested. Word of mouth works hopefully. Good luck growing stronger online.
Excellent video again. Here is very cold in winter so keeping warm is of course essential. While clothing isn't an issue finding gloves that keep your hands and fingers at least warm while being able to operate your camera has always been a problem. As I go skiing in winter I have some very warm ski gloves that also have a thin, soft but warm inner glove. I tried just wearing the inners for photography, problem solved. While your hands will still get a little cold if you are holding your camera for extended periods for the most part they will keep warm and it is very easy to operate the camera and push and turn the buttons and dials. Highly recommend ski glove inners
Having watched this a 2nd time I think I'm beginning to get the gist of the infinity issue.It'll be interesting to see If I can stil remember it in the morning! Great show as usual, thanks.
Thank you again a great show. Practical advise on clothing from Harry, and watched the piece on infinity several times. I think I have got it now, thank you. Also loved the photo shoot with Xiana, she is sooo cute.
I loved my visit to Glengarry Castle, the food was fantastic, the staff amazing, and my pictures of the wrecked boat were some of my favorite shots during my stay in Scotland. Most definitely a great place to use as home base.
OMG poor Harry! Although i feel sorry for him, it did make me laugh! I think he and Sheanna was the stars of the show! Thank you guys for a great show, you've made my night!
Hi a wonderfull explanation of infinity. I am wondering if there is some boundaries that share with the hyperfocal distance or is the same.... I am starting to be confused so thanks in advance if could you provide a bid of light about. Greeting from Colombia south america
Hi. Thanks for taking the time to comment. Infinity focusing and hyperfocal focusing are closely linked and you really need to understand 1 to fully utilise the other, but they are ultimately separate things. Infinity is governed entirely by focal length whereas hyperfocal is influenced by aperture and distance to subject, as well as focal length (plus other things such as enlargement of file and viewing distance). I hope that clears things up a little. Keep watching to learn more!
Thanks for another fantastic show. Harry's clothing segment was both excellent and hilarious, and loved the segment with Marcus' daughter. Such a great idea to contact print a contact sheet. I'll have to remember that for when my children are a little older (as in, can sit still and won't immediately crawl to the camera to put their fingers on the lens...)
Poor Harry…and as cold as it gets..took his breath away withe that cold water🤦♂️🤦♂️😂….thank you new to this channel, great info. Happy New Year…and Harry stay dry 😊
Another great episode! You guys are awesome! I am certain that we don't see the amount of hard work put into these shows, but we do appreciate it! Thanks so much!
Really enjoyed that - the infinity piece was good, I never really thought about it in such detail before. The outdoor kit was rather appropriate for this time of year, I need to invest in some good outdoor clothes. I was really getting into the analog technique but you cut it off at the really interesting part - I guess I’ll just have to watch the next episode in 2 weeks 😁
Great video as usual…. Hope you don’t mind Harry to add to your clothing part if a photographer is on a limited budget that they can buy good military clothing from military surplus stores at 1/3 of the price from high street stores for hiking boots, waterproof, backpacks and camping gear etc… Also bashas make good portable hides and with military scarfs over lenses you can blend into the background… BTW Harry winter is coming and revenge is sweet when served cold…
Great show. A question on the Infinity "rule of thumb " : is it dependent on strict focal length - ie 50mm lens, infinity commences at approx 50 meters - or is it fov dependent? Ie - micro four thirds 50mm is 100mm fov equiv, so is infinity commencing at 50 meters or 100 meters? The note about focusing one third into the pre-infinity distance is very helpful, because I've often found the one-third rule doesn't work for total scene depth.
Great video! I wanted to ask, if I'm using a lens with an infinity focus option (Sigma 17-50mm f2.8 for example) for videography and I'm zooming in and out a bunch, will it keep all objects beyond say 50 meters in focus? I ask because I film tornadoes from at least 100 yards away and want to be able to zoom in close when debris is being lofted and zoom out to get a full view of it. I currently have the Canon EF-S 18-55mm f/3.5-5.6 lens where the focus changes when I zoom in/out, and manually focusing can be difficult in those intense situations.
Hi. Sounds like the last thing you need to be worrying about is a slight focus breathing issue! Maybe be more concerned about the thundering tornado only 100 yards away! However, all you need to do is a simple test. Focus at infinity at f/2.8 at 50mm, then zoom out to 17mm and see if something at infinity is still sharp. Hope this helps.
@@PhotographyOnline Haha words to live by! I've been told that because the inner barrel of my lens rotates when zooming in and out that infinity focus will only apply to whatever zoom I focused to infinity on. I did try my largest aperture (f/4.5), focused to infinity while at 55mm, and zoomed out and things seemed to stay pretty sharp.
Great programme as always guys, a lesson on DoF is never wasted, same with clothing requirements. But was I the only one to spot the typo at 18:34?? If so do I win the prize?? (blening)???
I am enjoying your videos greatly. Toronto is far from Scotland, but my mother was born in Glasgow. Always intended to visit. Current excuse is Covid-19. Hill country might be too challenging at this point, but lots of things look interesting.
I like learning new methods of focusing, i found To infinity and beyond fascinating and informative any chance of a more indepth vlog on the subject please.
Hi Timmy. Not sure how we could go into more depth as we’ve covered it all in the feature. It will appear in our forthcoming Essential Camera Skills series 2 if that helps,
Hi all, terrific show as usual, never thought about infinity that much but will do now! great piece on clothing by Harry, has he dried out yet? Xiana is going to be very knowledgeable on all things photographic, if she isn't all ready! 10/10.
Another great video but I thought I'd share a tip from the motorcycling world. If you're pulling on overtrousers and want to get them on quickly without having your boots snag, simply put a plastic carrier bag or something similar over your boot and then pull the trousers on - it works a treat and no more snagging.
The presentation on infinity was really an "ah hah" moment! I was wondering how I'd capture a timelapse of the night sky and foreground elements and keep everything "sharp"! Thanks Marcus!
Great piece on clothing. A little research on how the wildlife I want to photograph actually see light and colours helps me make subdued clothing colour choices.
There's definitely an issue with falling over when wearing Wellies around streams and rivers and slippy rocks. During warmer months I ditch hiking boots and Wellies and wear trail running shoes like Ino8s they stick you to the rocks like Spiderman. And expel the water as you walk.
Marcus, does the "rule of thumb" in relation to infinity apply to all formats, i.e. on an 80mm lens on a medium format camera infinity would be roughly 80 metres?
Hi Folks Additional thoughts on clothing. I use base layer longjohns in cold conditions. These together with waterproof trousers have allowed me to lie for hours in the snow with hares. Also regarding gloves you can versions which allow the fingers to be uncovered to control camera function. My favourites are from the Heat company but in warmer conditions Sealskinz shooting gloves have worked well
Great video. I’ll be changing the way I photograph landscapes in future because I’ve always used the focussing a third of the way up the screen method. Will there be a difference when using a crop sensor camera?
Another great show. Thanks for explaining infinity, I’ll go back re-watch some of the earlier episodes now that we are heading into winter here in Canada. By the way, clothing is, here in Canada, very essential, especially in the coming months. I’m in a relatively warm area where day time temperatures can fluctuate from -10 C to - 40 C. Thanks.
Brilliant! You so clearly unwrapped the mystery of infinity focus. Thank you. Marcus mentioned using a phone to measure distance to a subject. What App is he using?
Regarding DOF how does subject distance and Aperture fit into your Example? You mention 16mm being were infinity starts when shooting at 16mm and focusing 1/3 of the way between infinity and the closest object you want sharp should render acceptable sharpness front to back. Surely the results would be different depending on subject distance and aperture? Otherwise one could have a object 60cm In front of the lens and shoot wide open at f2.8 and as long as I focus at 1/3 of the way to infinity everything should be sharp?
Hi Hayden. Thanks for your question. The only things which are ever truly sharp are those on the plane of focus. Once the plane of focus reaches infinity, it extends forever, so you only need to be concerned about covering up to where infinity starts - not any further. Hyperfocal focusing is where you focus in a scene to achive maximum depth of field, but this is dependent on so many other factors such as reproduction size of the image and viewing distance. So there is no set parameters for what where depth of field starts and ends for a specific scene/aperture/focal length as it is subjective to the viewer. You can however maximuse this area of "acceptable sharpness" by focusing approx 1/3 of the way between the closest object you want sharp and where infinity starts. In the example you gave, doing this will mean that the object at 60cm will not be sharp and neither will infinity, as neither of them are on the plane of focus. However, this would give the best compromise to getting both as sharp as possible. Using a smaller aperture simply makes the out of focus areas less out of focus - it will never make them truly sharp. Hope this helps.
With the general rule of infinity starts around the focal length of the the lens in meters, is this for full frame so you need to adjust this for the crop factor. So a 50mm lens on a crop sensor has infinity at 75 meters?
Cheers. We can’t really do a show based on the day it goes live as most people won’t watch it until a few days or even weeks later. Neither the R3 or the Z9 are available for review at the moment.
Hi, another very enjoyable show. Regarding infinity does a - say 50mm focal length - translate to an infinity start point of 50m apply to crop factor lenses as well? Thanks!
Great feature about infinity, depth of field and the relation of the focal length. Is this in theory also related to hyper focal distance? I never really understood the theory of the hyper focal distance... Great show as always!
Hi Stefan. Thanks again for watching. Infinity is t necessarily related to hyperfocal distance but it can be (it depends on your scene). We’ll do a feature all about hyperfocal distance in another show. All the best.
It was interesting with the relationship between infinity starting point and focal lenght. I wonder if it only applies to FF or if it also applies to MFT. Maybe you need to double the distance so that, for example, a 25mm lens has the starting point at 50 meters?
Hi Paul. Yes there is no reason why the smock can’t be worn with a backpack, but it would make h the front pouch inaccessible while you had it on your back.
Thanks for another great show. With regard to focusing, hyperfocal and infinity methods rely on being able to measure distances accurately. In the field this can be difficult at best. Do you have any suggestions to address this?
Hi Roger. You never need to measure any distances because you can simply look through the lens (magnifying the image) to see where infinity starts. The distance is actually irrelevant. Hyperfocal focusing is a dangerous thing as it can often lead to less sharp images. We’ll do a feature on that soon.
@@PhotographyOnline Unfortunately, the "depth of field" of my varifocal glasses (and eyes!) mean that looking through the lens is not going to work for me. I will continue to play it safe using focus stacking if needed. We should discuss this further in the bar at Uig next February!!
In the example of the closest object is 50 meters away and furtherest is 5km away....where does the focus point need to be? Anywhere in the scene between the 50 meter mark and 5km? Can i put the focus point at say 60 meters and have everything in "focus" using any aperature?
If you have anything longer than a 50mm lens, then yes. However, you won’t find a 60m distance mark on a 50mm lens (as that’s already pretty much infinity)
May i ask? whats happened to my favourite host Nick?? has he gone to greener pastures>?? The infinity focus was brilliant and. i know get it , i thought before just focus according to the infinity mark on the lens, i know fully understand it, brilliant once again
I have a question about the beautifully simple graph drawn by Marcus to help estimate approximate ‘beginning of infinity focus’ where we have focal lengths up the vertical axis and corresponding distance in metres along the horizontal axis. My question relates to crop factors and those focal lengths and consequent distance in meters. Does 10mm (16mm with x1.6 crop factor) mean that the near point of infinity focus is more like 16m rather than 10m? A long-winded but hopefully not stupid question. 😬
Hi Nocolino. It’s not a silly question, but you don’t need to compensate for sensor size. A 50mm lens will have the same distance to infinity, regardless of which camera it is being used on. Hope this helps.
@@PhotographyOnline thank you. Yes it does. Congratulations on running THE BEST photography RUclips channel bar none. I subscribe to dozens and each have their individual merits but yours is the complete package with a great mix of serious in-depth knowledge, practical advice, common sense approach and a nice dose of humour too. ⭐️👏🏼👏🏼👏🏼 Just thought you might like to know. Cheers from Perth. The Australian one.
That’s the longest discussion of hyperfocal distance I’ve seen that didn’t mention the term. In classical terms, the infinity setting is when the plane of focus is infinitely far away. The hyperfocal distance is the nearest point of focus at which things at an infinite distance remain acceptably sharp. This is affected by focal length, aperture and sensor resolution.
@@PhotographyOnline I've only ever known one definition of hyperfocal distance, as mentioned above. Due to your response I've done some searching and found an interesting page which I'll link below (if RUclips Lets me). You're using the term "infinity" to capture what I've always known as the hyperfocal distance. Now I know that there are really two schools of thought on the best terms for these concepts. I've been a photographer for many, many years and have found your videos to be both interesting and accurate, right up there with the best photo instruction I've ever seen. I was therefore surprised when your hyperfocal video was at odds with my understanding, and more surprised this time. Glad to know this is simply a terminology difference where there are two schools of thought, and neither you nor I are out on a limb. photographylife.com/landscapes/hyperfocal-distance-explained
Hi Ron. We’ve been trying to deal with Nikon for the past 6 months but they are not very interested in lending us any cameras. If they change their minds then we’ll try to feature some of their cameras.
Marcus: I have a question about where infinity begins for crop sensor cameras. If infinity begins at 50m for a 50mm lens on full frame, is it also at 50m for a 25mm lens on a m4/3 camera with its 2x crop factor?
Hi. Sensor size is irrelevant here, so a 50mm lens (regardless what camera it is being used on) will always have the same distance for infinity. There’s no need to compensate for different sensor sizes. Hope this helps.
Hi Rahul. Lenses will only fog up if they are cooler than the ambient temperature. If you can keep your lenses in a warm place then they will not fog up. Avoid keeping them in an air conditioned room before taking them out into a warmer environment.
just a suggestion since you cover so much on the infinity why not do another episodes explain the infra-red infinity on the scale. and how to focus star at night at infinity skill?
Hi. We’ve already done a feature about focusing on stars - in our Aurora feature at the beginning of the year, so feel free to check that out sometime. Thanks for watching.
I keep watching this section on Infinity to make sure it's always very clear to me when i'm outdoors, thanks Marcus.
Great to hear!
I love hearing the mirror slapping up on the Mamiya. I have an RB67 and love it.

In the example you gave, doing this will mean that the object at 60cm will not be sharp and neither will infinity, as neither of them are on the plane of focus. However, this would give the best compromise to getting both as sharp as possible. Using a smaller aperture simply makes the out of focus areas less out of focus - it will never make them truly sharp. Hope this helps.
With the general rule of infinity starts around the focal length of the the lens in meters, is this for full frame so you need to adjust this for the crop factor. So a 50mm lens on a crop sensor has infinity at 75 meters?
Hi Larry. No adjustment is necessary as infinity is only dependent on the focal length, not the sensor. Hope this helps.
D850 is the best DSLR ever. I am a Canon shooter, so not very happy about it :)
And yes, we would love to watch you eat :D
Thanks for your input Eric
A great episode. I learned something new and valuable with the infinity focus feature. Who threw the water at Harry? My money’s on Marcus
You would be correct!
Great informative show as always!
Was expecting to see photographing of ghosts on Halloween 😂.
R3 vs Z9 will be an interesting watch :-)
Cheers. We can’t really do a show based on the day it goes live as most people won’t watch it until a few days or even weeks later. Neither the R3 or the Z9 are available for review at the moment.
Hi, another very enjoyable show. Regarding infinity does a - say 50mm focal length - translate to an infinity start point of 50m apply to crop factor lenses as well? Thanks!
Hi Kevin. Sensor size is irrelevant here, so it's only focal length which you need to use in your conversion. Hope this helps.
@@PhotographyOnline Very helpful.Thanks!
Great feature about infinity, depth of field and the relation of the focal length. Is this in theory also related to hyper focal distance? I never really understood the theory of the hyper focal distance...
Great show as always!
Hi Stefan. Thanks again for watching. Infinity is t necessarily related to hyperfocal distance but it can be (it depends on your scene). We’ll do a feature all about hyperfocal distance in another show. All the best.
Great show, except who is the water sadist? I also look foreword to a hyperfocal discussion since the infinity wall isn’t how I see things. Thanks.
Marcus won the bid to throw the water. We will do a hyperfocal feature in the future.
"To infinity...& beyond..." And Sheanna was as cute as a button with her emoticons...
Thanks for watching. All the best.
Looking forward to it already
It was interesting with the relationship between infinity starting point and focal lenght. I wonder if it only applies to FF or if it also applies to MFT. Maybe you need to double the distance so that, for example, a 25mm lens has the starting point at 50 meters?
Hi Arne. It makes no difference what camera you use, it’s just the focal length of the lens which is important. So no adjustment is necessary for MFT
Great show again, thanks.
One question, do you think the smock jacket that Harry was showing, would be suitable for wearing a backpack?
Hi Paul. Yes there is no reason why the smock can’t be worn with a backpack, but it would make h the front pouch inaccessible while you had it on your back.
Thank you very much for your advice
Thanks for another great show. With regard to focusing, hyperfocal and infinity methods rely on being able to measure distances accurately. In the field this can be difficult at best. Do you have any suggestions to address this?
Hi Roger. You never need to measure any distances because you can simply look through the lens (magnifying the image) to see where infinity starts. The distance is actually irrelevant. Hyperfocal focusing is a dangerous thing as it can often lead to less sharp images. We’ll do a feature on that soon.
@@PhotographyOnline Unfortunately, the "depth of field" of my varifocal glasses (and eyes!) mean that looking through the lens is not going to work for me. I will continue to play it safe using focus stacking if needed. We should discuss this further in the bar at Uig next February!!
In the example of the closest object is 50 meters away and furtherest is 5km away....where does the focus point need to be? Anywhere in the scene between the 50 meter mark and 5km? Can i put the focus point at say 60 meters and have everything in "focus" using any aperature?
If you have anything longer than a 50mm lens, then yes. However, you won’t find a 60m distance mark on a 50mm lens (as that’s already pretty much infinity)
Where else can you get advice on proper clothing?! That's something that I never think about. Time to change that. Great show as always....Thanks!
Not sure where you can get advice on photography clothing - which is why we did a feature on it. Hope it was helpful. Thanks for watching.
@@PhotographyOnline @Photography Online Yes it was. I should have specified: "...proper clothing for a photography outing...". That's what I meant.
May i ask? whats happened to my favourite host Nick?? has he gone to greener pastures>??
The infinity focus was brilliant and. i know get it , i thought before just focus according to the infinity mark on the lens, i know fully understand it, brilliant once again
Hi Donald. Nick is still here but he’s been super busy with workshops recently so hasn’t had time to do any filming. He’ll be back in the Dec show.
I have a question about the beautifully simple graph drawn by Marcus to help estimate approximate ‘beginning of infinity focus’ where we have focal lengths up the vertical axis and corresponding distance in metres along the horizontal axis. My question relates to crop factors and those focal lengths and consequent distance in meters. Does 10mm (16mm with x1.6 crop factor) mean that the near point of infinity focus is more like 16m rather than 10m?
A long-winded but hopefully not stupid question. 😬
Hi Nocolino. It’s not a silly question, but you don’t need to compensate for sensor size. A 50mm lens will have the same distance to infinity, regardless of which camera it is being used on. Hope this helps.
@@PhotographyOnline thank you. Yes it does. Congratulations on running THE BEST photography RUclips channel bar none. I subscribe to dozens and each have their individual merits but yours is the complete package with a great mix of serious in-depth knowledge, practical advice, common sense approach and a nice dose of humour too. ⭐️👏🏼👏🏼👏🏼
Just thought you might like to know.
Cheers from Perth. The Australian one.
I replayed "taking the worst the weather(water) can throw at us" for 5 times and I still can't help to laugh .sorry Harry!
Great to know you found it entertaining.
Another Contender; Pentax K1 Mark II with the new Pentax DFA*50 1.4 in Pixel Shift Mode on tripod.
Thanks for the suggestion - we’ll add it to the list. Thanks for watching
Another great show, infinity piece was really interesting, a bit beyond me to begin but I think I’ve got it now. Hope Harry has dried out now.
Cheers Steve. Thanks again for watching
That’s the longest discussion of hyperfocal distance I’ve seen that didn’t mention the term. In classical terms, the infinity setting is when the plane of focus is infinitely far away. The hyperfocal distance is the nearest point of focus at which things at an infinite distance remain acceptably sharp. This is affected by focal length, aperture and sensor resolution.
Hi John. This wasn’t a feature about hyperfocal distance. It was a feature about infinity. We covered hyperfocal distance last month.
@@PhotographyOnline I've only ever known one definition of hyperfocal distance, as mentioned above. Due to your response I've done some searching and found an interesting page which I'll link below (if RUclips Lets me).
You're using the term "infinity" to capture what I've always known as the hyperfocal distance. Now I know that there are really two schools of thought on the best terms for these concepts.
I've been a photographer for many, many years and have found your videos to be both interesting and accurate, right up there with the best photo instruction I've ever seen. I was therefore surprised when your hyperfocal video was at odds with my understanding, and more surprised this time.
Glad to know this is simply a terminology difference where there are two schools of thought, and neither you nor I are out on a limb.

A great explanation of infinity focus but did it cause Marcus to chip a tooth?
Haha. It is chipped but it wasn’t caused by infinity! It’ll be repaired soon!
Can we have a review of the Nikon Z9 please?
Hi Ron. We’ve been trying to deal with Nikon for the past 6 months but they are not very interested in lending us any cameras. If they change their minds then we’ll try to feature some of their cameras.
Does the 'rule of thumb' infinity method hold true for crop sensors, or do I need to convert to full frame equivalent first?
Hi Peter. Sensor size is irrelevant here, so the rule of thumb only applies to the focal length. No adjustment needs to be made. Hope this helps.
@@PhotographyOnline Brilliant. Thanks. :-)
To infinity and beyond 😉👌📸
You know it
Marcus: I have a question about where infinity begins for crop sensor cameras. If infinity begins at 50m for a 50mm lens on full frame, is it also at 50m for a 25mm lens on a m4/3 camera with its 2x crop factor?
Hi. Sensor size is irrelevant here, so a 50mm lens (regardless what camera it is being used on) will always have the same distance for infinity. There’s no need to compensate for different sensor sizes. Hope this helps.
Interesting. I will have to experiment with this new knowledge. Thanks!
Love it
Hi Di. Thanks for watching
How do we avoid fogging up of the lenses in humid weather?
Hi Rahul. Lenses will only fog up if they are cooler than the ambient temperature. If you can keep your lenses in a warm place then they will not fog up. Avoid keeping them in an air conditioned room before taking them out into a warmer environment.
@@PhotographyOnline if an air conditioned room is my only option, then I would need to aclimatize my whole kit before using, correct?
just a suggestion since you cover so much on the infinity why not do another episodes explain the infra-red infinity on the scale. and how to focus star at night at infinity skill?
Hi. We’ve already done a feature about focusing on stars - in our Aurora feature at the beginning of the year, so feel free to check that out sometime. Thanks for watching.
Best camera is a Hasselblad with phaseone digital back. Crazy expensive. Yes.
