Great and comprehensive review. Ironically, my EF40/2.8 has had more use on my GFX camera than it ever did on my full frame body.

Same here! It is my go-to walk around lens for the GFX, never used it in full frame days.

I have this exact combination for my GFX-100. I've got lots of Canon stuff and the 40mm STM was in my kit. I bought the Fringer EF-GFX Adapter and a GF-45mm at the same time. After using the Fringer EF-GFX Adapter and the Canon 40mm STM, I returned the GF 45mm as I didn't need it for $1800 after using the STM 40mm.

looking good thanks

Good job,I got same setup

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!

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?

There were 2 copies at MPB before I grabbed one. Loving it on my New 5D mark II, it makes my camera more portable and the lens is Sharp, great for street photography

Hah, enjoy, and thanks for watching! :)

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 .

Thanks for watching! I never planned to use it for video (I do all my video on the X-S20 and X-T3), so have never actually tried! Would be interested to hear how it goes. It is a bit old, but the STM AF motor was designed specifically for Canon's earlier live view cameras and keep up with the video feed, so it's very possible. Good luck!

I use this little beauty on an R5 and it is incredible.

Great lens (and camera)!! Thanks for watching. :)

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.

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

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

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.

I guess so . I have canon 85mm 1.2 L and on Fringer adapter if you switch AF to off mode on the lens , there is no AF. Should be same on 40mm 2.8 And Fringer adapter is the best for gfx. You should pick that. Don’t take Techart , it’s so bad. I’ve had and Fringer is lightning fast compared to Techart

I will say this much, if you’re interested in this combination I would strongly advise saving a bit extra for the native 50mm 3.5! It’s an absolute gem of a lens and it’s not bank breaking.

Agreed! I think the GF 45mm 2.8 is even better, but obviously a different size/weight class. Thanks for the comment and for taking the time to watch! :)

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

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

@@HealingMushroom It works great with the Viltrox adapter, with the newest update even the vibration control works fine. Image quality wide open is exelent, exept the far corners, there ist a little drop down in resolution. The longitudinal CAs are lower pronounced, than with fullframe. The only downside is, that the Tamron doesn't look so good on the Gfx, if this is important.

Could you please do one on the Pentax 645 45, looking into this but worried that it might be 13cm long with the adapter and lens combo?

It's on the list, and I actually have it here. Would you just like me to measure it for you for now? You just looking for total length with adapter + lens?

@ytshank

@@HeritageFocus yes please, the total length and if you could check the total weight as well. That would be amazing. BTW does putting a 645 lens on a GFX which has a smaller sensor than the 645 film, change the crop factor. I read somewhere that you need to multiple the Focal length by 1.2. So the Pentax 45 mm would be a 54mm on the GFX. Similar to how a 50mm lens for Full frame on a APSC turns into a 80mm due to the 1.6 crop factor.

@@HeritageFocus Thx for the info, now its a choice between the Pentax 45mm or the Mamiya 45mm. I really wish there were MF lenses with a shorter flange distance to reduce the overall length of the setup.

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..

for light weight EF40 always on my camera but it 1000 steps away from GF50 for image or AF quality.ef40 just lighter and a bit faster for use only in gfx sensor centre....so dont fool here...

No one is comparing 40mm EF to GF50 . Different beasts … one is for full frame the other is for medium format capable of resolving 102Mp. . (60+lines/mm)

So the lens is sub 100 dollars and the adapter is 500? What a buy!!

how do they adapt to the GFX sensor? is there any extreme vignetting or loss of sharpness around the corners etc?
