The Voigtlander APO-Lanthar 65mm f2
Fully mechanical, and it could cover a bigger image circle (definitely at close range, maybe less so at infinity). Also, it was designed with the thicker sensor stack in mind in the first place, so it might not smear if it actually covers it. Reasonably priced for its sharpness, and the focal length could become more standard. Somewhat big for an E-mount prime lens, but much more normal in the GFX world.

So I wonder if the mount can be exchanged to a GFX one, it's definitely a custom job...does anybody want to try that?

I guess

Unfortunately I think any e mount lens is a no go. Flange distance of e mount lens is 17 mm while GFX flange distance is 26.7 mm so any lens specifically design for E mount should not work regardless of adapter.

The back element is quite recessed, so it might just be possible, but there are way too many question marks.

Update: I see what you mean, the housing that sticks out after the mount part won't fit inside the GFX mount

Here are some shots from High Park in Toronto. Some with the Hassy HC 100 f/2.2 and others with the Hassy HCD 24 f/4.8. Both of these lenses perform wonderfully on the GFX.

Here are some more shots with the Hassy HC 100 f/2.2 and the HCD 24 f/4.8. These are from Asilomar beach in Pacific Grove, CA (near Monterrey). I think these do a nice job of demonstrating the DR of GFX. I don't think I could have got the surfing shots even with my Sony A7rII.

I purchased the adapter exclusively for use with the tilt-shift lens, but I'd be lying if I said I wasn't curious to see what coverage is like with the rest of my Canon glass.


Hi have you made any progress on testing these lenses with the Kipon adapter?

FWIW, info gleaned from discussions about adapting some Canon EF glass to shift adapters such as the Hartblei HCAM Master TS, indicated you can improve image coverage for some of the zoom lenses, such as the 16-35/4 by removing the rear plastic baffle inside the lens mount. Image circle coverage, IIRC, increases towards the longer end, though this is also the weaker end of the lens.

See page 5 of this thread, I made a post on Aug 18th with a brief summary of the results and my thoughts for each lens when adapted to the GFX, and a separate post on Aug 19th with a sample image or two shot with the Sigma 50mm f/1.4 Art. For additional images shot with the GFX and Canon EF mount lenses, I have several Colorado/Wyoming landscapes on flickr shot with the 17mm TS-E and at least one photo shot with the Sigma 50mm f/1.4 . I've already sold the 24mm f/1.4 II and 35mm f/1.4 II, but I have a few test images shot with those lenses somewhere on my computer. The 35mm f/1.4 II was actually pretty decent for the most part (it's an awesome lens on 35mm), but it had more vignetting than the Sigma 50mm and bokeh in the corners had a heavy cats' eye look. The 24L II also suffered from heavy vignetting. The 100-400mm combined with the GFX has proven convenient to have in a pinch for shooting telephoto landscapes, but cropping is required due to the heavy vignetting past 135mm (I decided to keep that lens and a 7DII so I have something better suited to shooting wildlife than the GFX). The other zooms (16-35 f/4, 24-70 f/2.8 II, 70-200 f/2.8 IS II) were all pretty bad with respect to vignetting, the 70-200mm had quite a bit of pin cushion distortion past 180mm. I think that just leaves the 100mm f/2.8L IS Macro, that lens is pretty solid on the GFX, some vignetting at longer focus distances wide open, but it cleans up reasonably well on stopping down and has very little vignetting at macro focus distances. Resolution is very high as well - some full res links (about 20MB each) - this is the lens stopped down to f/14 https://c1.staticflickr.com/5/4397/37001854672_f4df68a729_o.jpg Another at f/11 (I believe this was at 1:1) - https://c1.staticflickr.com/5/4349/37025672202_4ffb45cfee_o.jpg

A few comments on the TS-E 17mm - I'm still trying to get a feel for this lens on the GFX. It doesn't seem to play very well when using tilt, does a bit better with shift, but you really need to stop the lens down to get decent corners (f/13 through f/16 seem to be the sweet spot). I think there might be some field curvature going on, or (more likely) my filter setup is killing resolution at the edges. I need to shoot more with the lens without a CPL or ND mounted.

16-35mm f/4L IS - a fair amount of mechanical vignetting in the corners at 16mm until about 20mm, I guess it's usable past 20mm if you don't mind the traditional vignetting. Given that I own the 17mm tilt-shift and am planning to purchase the Fuji 23mm f/4 (mostly so I'll have access to a weather-sealed ultra-wide), I doubt I'll hang on to this lens much longer.


I just read back through the thread and noticed your post before coming back to this page and seeing that you posted again. As I noted above, it's possible to remove the 16-35/4's rear plastic baffle to eliminate some of the mechanical vignetting, though not sure how much improvement it will make with the GFX's sensor.

Re: TS-E 17 - back in ~2009 when it was released, it was pretty impressive, but I think it's starting to show weaknesses on the current ~40-50MP sensors, particularly when shifted. Seems Nikon's new 19 might be a better performer.

Anyone tried the Canon 200 f/1.8L? It would be insanely interesting to me if that lens covered this sensor, even if it required stopping down a stop or so (an effective 150 f/1.2 doesn't seem that useful to me anyway).


I realize this is an old post, but wondering how you would focus an old Canon fly-by-wire USM lens, such as the 200/1.8? Are there any adapters that provide power for aperture and drive focusing motors?

Sharpness is just one factor, rendering style is another important factor of lenses and just like a lot of us in this forum enjoy shooting older less sharp, lenses with character on our FF cameras, why can't people enjoy shooting older glass or non native lenses on miniMF? Seems like normal alt forum behavior to me.


Do you have a GFX Wayne?

...and tilted. Even 1 or 2 degrees degrades the corners substantially even at small apertures. It's the only TS-E that imo needs a refresh.

Even on my 22MP 5DIII I could see the weaknesses of the 17mm TS-E when using a full 12mm of shift. On the GFX, I've mostly shot with with the lens as a prime (i.e., no shift/tilt). The wider field of view the lens offers on the GFX has been entertaining to experiment with, and I love working with such flexible files (there is a night and day difference between the raws coming out of my old 5DIII and the raws produced by the GFX).

Yes, now that the 45 has been replaced by the new 50/2.8. Obviously the reason for the 17 is its shift (and to a lesser degree, tilt) capability, otherwise the recent UWA zooms, like the 16-35s and 11-24, 12-24 from Sony, etc., are extremely impressive performers on FF. Not sure how any of those, at least from Canon, hold up on mini-MF

Did anyone try the TS-E 24? I just saw a Clyde Butcher FB video where he had the GFX with either a TS-E 24 or 17 mounted on it.
Probably the 24 after what you are saying about the 17.
Wonder how that compares with native GF 23?

In reply to Wayne - I've been impressed by the performance of Fuji's native glass so far. I suspect the GF 23mm is a better performer wide open on the GFX than the 24mm TS-E II @ f/3.5 without movements - but I also suspect we might be splitting hairs. And hey, if you need movements, you need movements. I could make a case for owning both.

The 17mm TS-E is a different beast, it was a very ambitious design, and makes more compromises (which I suppose are acceptable given the unique characteristics of the lens). Some negatives: color could be better (the images I shoot with the 17mm are less saturated and have less contrast compared to most of the other glass in my bag), the front element is very exposed and is susceptible to flaring/further loss of contrast (which is a big part of why I'm a fan of the fotodiox wonderpana hood, despite the almost comical appearance when mounted), I don't find the sunstars produced by the 8 bladed aperture very attractive, there is a very noticeable drop off in resolution towards the edges of the image circle, particularly at wide apertures, and I agree with Fred's comment regarding performance drop when using tilt (at least when the lens is mounted to the GFX). It can also produce images that few other lenses could - after you've become familiar with the performance characteristics of the lens, it can be a very fun lens to work with.
