Which adapter is better?

Is it there similar lenses with this characteristics? Thanks.

I don't think it was fair to compare the weight and size of the GF120mm with a Mamiya 120mm - the Mamiya offers 1x while the GF120mm would require at least the (very expensive) 45mm extension tube, increasing the bulk and weight and even then the image quality would be far below the Mamiya.

My lens has nowhere near as much vignette as shown in the video. Just some very little piece of the corner. Two things to keep in mind. I have the older version, with metal focus ring. And I take the lens hood off - it vignettes on GFX. I made a bigger lenshood with a 55-67mm step up ring and a simple metal lens hood. And the vignetting is just super minimal. Near non existing at closer distance and really only showing at infinity - which you rarely use this lens at.

The filter size is 77mm.

A wonderful video, some cracking pictures and super cool delivery.

It's better to understand any lens before running a rant on that.

It looks like a Medium Format look.

Several wrong information given.

"autofocus is useable" yeah try that on a C645 body

Hi! Thanks for the content! Trying to make my GFX camera into X100 version but 28mm FF focal length. Its for everyday carry so I dont mind it being manual or auto focus. Do you have any recommendations that is a compact, covers the 44x33 very well that is 28mm FF equivalent? I wished voigtlander 35mm f2 to be one but can't find much information on it. Thanks a bunch!

Looking for a method for scanning negatives with my GFX 50R I purchased a PK adapter to use with my Pentax smc A 100mm f4 macro lens. Amazing! no need to use crop mode, hardly any fall off in the corners and no smeering, sharp corner to corner at f11which I use for negative scanning (with extension tubes). So tried my 50mm f1.7, some poor corners at f1.7 but all good by f4, an amazing lens. So my last remaining Pentax lens smc A 70-210mm f4 again very good, probably may replace my P 645 80-160mm due to weight difference. I have long suspected that my copy of that zoom lens was better IQ than average hence why I still have is when not using Pentax now.

I have been using a Pentax 645 80-160mm and have been impressed once stopped down half a stop or more. Heavy thought stuck out on the end of the adapter! At least my adapter has a tripod shoe which makes a ballanced handle. With the exception of the 90mm APO, my Voightlander VM lenes are disapointing even in 35mm crop mode when wide open.

Good job,I got same setup

Would’ve been nice to include moving into the AF test. Otherwise it’s impossible to see how good the tracking in AF is.

Good video but please... once it's established you are talking about a "lens", you don't need to say it every sentence... it hurts my ear holes.

It will be great if this adapter come with 0.8x speed boosts things

Maybe next time include some 100% sized views of the images. Seeing images zoomed out to full screen says or shows very little of the actual sharpness of a lens. Especially if you also leave out the specific F-stop used in every image. There is little to play with here. Is the lens sharp wide open at F2.8? Does it get much sharper at F8? How does it perform at 50MP? Only questions, no answers.

A good test to see whether a lens can outresolve the GFX sensor is to put the aperature at f/5.6, take a photo, then do a pixel-shift multishot under the same conditions. If the pixel shift image has more detail than the regular photo then you know the lens is capable of outresolving the GFX sensor. The aperature is important here because beyond F/7.1 you will be diffraction limited and pixel shift does not help. Then if the lens is too wide open you will have to deal with abberation induced blur which could cause blur limited performance. Again, pixel shift will not help. F/5.6 seems like the general sweet spot where many lenses are sharpest. You also know the performance will not be diffraction limited, because that limit is f/7.1.

And zero information or opinion regarding ease of assessing critical focus with this lens.

the price of 80mm f/2, what do you think?😮

Woof so pricey but such a great lens.

I was wondering if you tested the much talked about Tamron 35mm 1.8 on the GFX?

Nice. Have you seen Nikon 85mm 1.4/G lens mod to GFX mount? It also supports AF and other electronic communications.

This lens is an absolute bargain..!! I had it on my 6d for years was almost never left the camera. It is almost the perfect lens. It is sharp. It is bright. It is stupidly cheap. It is small and make the whole setup look much less professional when do street photography. Extreme light, like there is no new in the camera. I have made some of my best shots with it..

Great video! I was looking exactly at this combo for my gfx 100 II. Are there any other 'faster' lenses that are comparable to this one, that you can recommend?

All my minolta and m42 lenses are cheaper, faster,have aperture ring and character plus the adapters are $35.00

Thanks for all of this, I've got alot of medium format lenses and going to get a gfx body soon.

What about the Tamron 45mm 1.8? It has a very wide open aperture and the image circle covers the sensor very well.

I lucked out and picked up one of these as my first vintage lens. I use it on my 60 mp full frame sigma FPL, and I love it. I think an APSC sensor under utilizes it, and the medium format is asking it to do more than it was designed for. I assume the GFX has a crop mode which makes it act like a full frame? The optical vignetting causing the very busy bokeh around the edges of the medium format sensor are not an issue with the full frame sensor.

You've probably already reviewed it but I love my OG version one Canon 25-105 f/4 on the GFX.

Best video of the century. I’ve been shooting Fuji for six years and now use the XE4. I constantly think about upgrading to full frame or GFX 50 R. I love the XE4 size and only use the f2 primes. I would keep doing these type of videos. I think they would eventually get popular.

Very interesting test, sir! As a Nikon Z System landscape, wildlife and small product photographer, I am currently evaluating MF systems such as the Fuji GFX 100 ll, and the Fujinon lenses. I would have liked to see a side-by-side image taken with both the Zeiss and the Fujinon GF equivalent lens, but how would you compare the central sharpness between them? Thank you!

I got one from KEH based on this video. Thank you for making this video. You earned a sub from me!! I payed $119 (USD) for Excellent Condition on 2023-01-30.

You got awesome, great quality videos!! Please make more if these and consider patreon! ☝️💥💪❤️

Thank you for the great, and very helpful, review! I already have the Steelsring II adapter, which I purchased some time ago at the same time that I purchased the 120mm ƒ4.0 makro. I have been wanting to get the 80mm for a long time, but it seemed that all the nice ones were over $3,000; too much for me. Your Target Price made me feel much better about the one I purchased today on eBay. I found an 80mm in near mint condition for $2,138, delivered, from a store in Japan. I think it's the same store that I got the 120mm from. But anyway, I know I have purchased from them before. I had the GF110mm for a while, but I found that I rarely used it. It was too heavy to carry around, and it made an annoying noise all the time. I think it had something to do with the AF motor constantly checking on things.

For anyone adapting vintage glass to the GFX there is a list available online of tons of old glass and whether or not it covers the GFX sensor (its community maintained although im not sure if its still being updated). Even on glass that does not cover the whole sensor it can still be used in the GFX 35mm crop mode, although there are some surprising entrees on that list (i picked up a 28mm f2 nikon lens and a 300mm f4.5 minolta that both cover the entire sensor with some vignette wide open). Whether youre looking for something wide or tele, heck i think theres even a couple of zooms that work, the list probably has something youre looking for and has been a great resource for me.

did u not use the 35mm crop mode in the gfx?

I used one of these until I got the GF 50mm f/3.5 for $350. Essentially the same experience.

Dear Heritagefocus team firstly I want to say that finally I found a place where people do real, fast, simply and accurate tests of lenses, great job! I am standing before buying GFX system but also I want to invest in some vintage 645 lenses, cuz also I am going to leave my 67 format and go to 645. I can't decide mamiya .vs pentax. Have you tested, or are you plannig to do some of mamiya ~75, ~55 shoots? Also it's really hard to find pictures made with that KIPON adapter with 0.8 lens inside. Its pretty expensive but maybe is it worth to pay and get that full medium format look/ deph of field/ 100% usage of lens. Thanks for any help! Best from Poland Marek

Why would you get the Canon version with no aperture ring???????🤦‍♂️

Overall not a great lens I think. There are plenty of good alternatives out there which are much much better imo

Had good laugh on the food references, my buddy and I relate costs of lenses to how many McChickens it is!

Dumb question, hope someone can help. I'm looking to purchase the gfx 50r and love it for the 65:24 panorama (closest I'll get to xpan). Does anyone know if i can still shoot 65:24 with Minolta lenses?

This lens looks great, I kinda want it. Just need an adapter first. The only adapted lens I have (that I use) is the Canon FD 135mm 2.8, which I use on my crop sensor fujis. It’s pretty good, even wide open on the new 40mp sensor.

Hello, Thanks for the video. I bought a version of this lens (the A) to use with Fuji GFX 50R for scanning negatives. I have a Fotodiox adapter. The f-stop ring moves, but I am not seeing the diaphragm/aperture change. I moved the switch from A to M and still no movement of the diaphragm. Am I doing something wrong? Or is this lens damaged? I do have the 80mm macro and that seems to work fine on my setup. I thought this would be the same. Thanks.

@1:51 giant fingerprint on rear element

Thank you a lot ! Excellent video. As owner of gfx 50s and gfx 100, I really want get it to pair with my Fringer adapter. It’s a little sad you didn’t tried video mode to see how is the framing , because it’s smaller than shooting mode, and af in video mode. Do you think it has a good enough AF? I’m looking to film some interior interviews, I hope it’s wide enough but I guess something between 20-35mm would be better for interior videos .

On the Fringer and Techart adapters, is the focus ring correctly disabled when the lens's AF switch is set to AF? It remains enabled on the Viltrox adapter, and if you manually focus this way, the lens fails to autofocus correctly from then on until you restart the camera.

Mamiya 150mm f/ 2.8 and 210mm f/4 it is better...
