This is the PERFECT video for EVERYONE that constantly misunderstands crop sensors and the math of crop factors ESPECIALLY towards lenses. I argue all the time with other photographers that multiply the MFT crop factor to the lenses that it still doesn't change the light gathering ability of that f-stop! Thanks so much for making this video!
One thing that isn't mention in the video is that isn't possible to have exactly the same composition, the same image, if the background is somewhat far away because of the compression. Different focal length have different rendition of the background because of the angle of view. In my opinion the bigger the sensor, the better, mostly in wide angle compositions because you use longer focal lengths. It would be great if you make a video explaining the compression, because people misunderstand the topic sometimes. The compression is because the focal length, and it's haven't direct relation with the sensor size.
I came across ur R7 Videos because I want to buy one...and since th watching you I am getting so much camera knowledge and learning more each day. I mainly shoot video and I think the R7 is going to do me well.
@@Josh_Sattin It happened the same to me, I want to buy an R7 so I was watching a lot of videos and ended in this channel. It is pretty cool, thanks for all the info Josh, it´s very easy to understand :)
Your theory is all correct. But unfortunately your example using the crop factor on the Sony is incorrect. All your theory assumes that the resolution size of both sensors is the same i.e. pixel size or the crop sensor is smaller. When using the crop factor in the Sony you’re not changing pixel size but are changing resolution. Depth of field is affected by the pixel size. Noise is affected by the pixel size.you needed to use a crop sensor of the same resolution of the full frame camera.
Wow you really did a great job with this video and explaining the subject matter. Honestly, I’ve seen a lot of videos over the years explaining this subject, and I sincerely think that this is the best one I’ve seen.
8:39 The crop mode on FF uses all the pixels? Or is it digital crop? If it is digital crop than the pixel size is the same as in FF mode and not denser, just less megapixes. The video is very informative but the examples should have been from both FF and crop cameras.
Bigger pixels means brighter pixels so the only real comparison is between a FF and a crop camera that both have the same megapixel count. If so there would probably be a difference in exposure.
Very well done. However you kept intimating that a larger depth of field is a bad thing. But when taken images of distant wildlife or macro bugs a broader depth of field if preferable.
Thank you. Oh, I didn't mean that, but a lot of people are obsessed with shallow depth of field. I 100% agree that a deeper depth of field is important in many situations. Thanks for watching!
I'm quite surprised to see the maths working out such that you should treat a 50mm lens as a 33mm lens on a super 35 sensor. My intuition tells me that you'd multiply by the crop factor, not divide by it. Wouldn't a 50mm lens be equivalent of a ~75mm lens? I checked with a couple of equivalence calculator tools and they agree with me. Wdyt?
Correct me if I'm wrong but there are '4' things that effect depth of field 1-aperture 2-focal length 3-distance to subject 4- Subjects' distance to its own background
Great question. The depth of field does not change based on how far away the background is. That is set based on the first three parameters. But... the further away the background is, the further it will be from the focus plane and thus more out of focus. The depth of field is just how much is acceptably in focus on either side of the focus plane. A lot of people do think that depth of field equates to how blurry the background is.
@@Josh_Sattin Oh snap my bad. Everytime I hear of depth of field I immediately think of blurry backgrounds. Thank you so much for clearing it up for me - and probably for many others out there.

I really don’t know how this doesn’t have a couple hundred thousand views … this is literally a gold mine of information
Thank you. That would be cool if it happened.
fantastic explanation in a fully understandable way -thankyou
You're welcome. Thanks for watching!
Fantastic video Josh! I like the way you presented it and stepped up the nerd factor a bit for those fellow nerds out there ;)
True 🍸
I just spent so long in the trenches of online forums about this - thank you, thank you, thank you! This is so much simpler of an explanation
You're welcome. Glad this video was helpful for you. Thanks for watching!
Thanks for this video. I've seen too many RUclips videos in which they apply the crop factor only to focal length.
You're welcome. Thanks for watching!
Hi, Josh. Finally I got it. Quite sharp explanation, nice work! Big thanks~

Thank you so much! It was a lot of fun to put this together and I hope it helps people out.
This is more instructive than many
Thanks for watching!

Tons of great info! Thank you! 🙌🏻🙏🏻

As a physicist and photographer, I thoroughly enjoyed this one Josh! Thanks!!
You’re welcome! Glad you enjoyed it!
Super thorough breakdown, Josh! 👍
Thanks! This was fun and nerdy!
I really liked your content!
It’s technical but not boring
You got a new subscriber !
Thanks for watching and for the support!

Loved this video so much shared in a few places!
Thanks! Hopefully its helpful for people!
#WINNING!
Does it work on cover crops? 😆
Haha. Wrong channel!
This was great!
Thanks! Glad you liked it!

Yeah, no worries. That’s a common misunderstanding. Hopefully this video and conversation help you understand it a bit more. Thanks for watching!
