thoughts on architectural with GFX, image circle and lens.

I also have a P645 55mm that I don't love... Mine suffers from flare from above. This example looks very good indeed..

That Canon 50mm TS-E though, looks amazing fully shifted at 12mm :)

Thanks for the test, very helpful....
Same here. I found the P645 55 pretty much unusable for interiors due to flare, but the Hassy 50 to be much better. However, the Canon 50 TS-E is a league apart from them.
 
Ur welcome, Gero.
It's really about 9mm, see graphics attached.
I only own the Mamiya 7 43 and 65 mm lenses which are rather symmetrical designs and provide excellent corner to corner sharpness on 6x7 film. The 65 was ok with FPS and IQ180 54x40mm sensor, the 43 had rather strong smearing towards the corners and color cast. So the 65 should be ok on the GFX, the 43 I must check, also I guess, the 43 back barrel already would interfere with the protection glass. Of course both need mount adaption and only can work because I removed back barrel parts and the electrical leaf shutter.

(I had Contax G 16, 21, 28 lenses but these already did not work well with an APS-C Sony camera, so I gave up on them and sold them, for Leica M I only have 50 and above.)
Hi Chris,
Any idea if these Mamiya 7 lenses would work better with the BSI sensor of the GFX 100? Would movements be possible if it was attached to a bellows type system? Would you be able to use the 43mm or would the rear interfere?

Thanks again for all your input! :)

When I had my X1D I used the Mamiya Sekor 50 Shift. Haven't used it since I have the 907x but it worked really well at a full 15mm shift on the X1D. Not super wide but really useable and not that big either.

Hi,
I search sample of architecture from Fuji GFX 50 with the last Pentax 35 HD with maximum shift and Contax 645 35mm with maximum shift. For the Contax, at f11, is the liveview usable for interirors ? Many Thanks !

I don't shoot interiors, but I do work in some very dimly lit forests where I'm frequently using f/16. The liveview display on the GFX 50R/S cameras starts to slow down and becomes a bit coarser in these conditions, but there's plenty of gain to allow me to compose and focus easily (with magnification).

Unless you're working in near darkness you won't have any trouble with liveview and f/11.

With the Pentax, smaller shifts only before distortion appears. It works quite well shifted vertically in landscape orientation, but laterally (or vertically in portrait orientation) hits complex distortion very quickly. I wouldn't want to focus at f11 with either lens though, that would be tricky for interiors.

Hi,
What do you think about this new Canon EF Lens to Fuji G-mount T Smart Expander 1.26x (GFX)?
I ordered mine direct from Metabones as soon as it was announced. The adapter is great, if a bit flakey - at least, I had to try a few times to get lenses recognized. The problem is quality control on Canon's side. I bought a 16-35/4 to go with the adapter, as that would be a perfect focal length range for me. Alas, the lens was decentered. Slightly, but enough to make the resolution pointless. I'm not going to play the "buy four copies to get one good one" game. For the 135/2 and even 85/1.2, it's an amazing alternative to existing lens options.

So 135mm and 85mm work well with this expander?

I shoot with 50R with Canon 24mm TSE, Pentax H FA 35 and Hasselblad CFE 50mm. As Owen commented, maximum shift in landscape works fine, distortion can be easily corrected in C1 under Contax 35mm lens profile, but portrait orientation shift gives unusable result, especially if you plan to stitch.

I'm much happier with the current focal lengths, saves me any stitching in the post production, plus 4.3 ratio captures just the right amount of ceiling and ground.

Let me know if you need more information on this setup please.
 
Has anybody managed to use the Schneider Kreuznach 35mm LS f/3.5 for Phase One on a GFX or any 44x33mm digital back WITH SHIFT? I would like to see how it performs. That focal length is very important to me - and Fuji has fallen into silence about native shift lenses ;-(

But there seems to be no adapter for the modern Phase One lenses for GFX that fits. Novoflex has an M645 adapter, but they say it does not fit physically with XF 645 bayonet mount. Does anybody know one that fits physically? (I can live with fixed aperture that I preset on a phase one body)

Capture Integration has an article where they mounted this lens on an Alpa camera (https://www.captureintegration.com/phase-one-lenses-on-an-alpa-camera-yes/) and could shift 12mm before they started seeing the edge of the image circle. But they did not test for image quality. Has anybody else?

Would be glad about any information.

I wish! I'd own one already if it were possible on my GFX 50R + VX23D outfit.

The flange distance for this lens in a Schneider Electronic shutter is 39.4mm, so it will be about that in a Copal 0 shutter. The rear barrel is 43mm and it projects 17.4mm past the mounting surface. GFX cameras have a flange distance of 26.7mm. That puts the rear of the lens inside the cavity of the GFX 50R at infinity. If you could mount it (I can't on my outfit), you'd have very little shift room. Worse, I've read (but not seen for myself) that it has horrendous lens cast on this kind of sensor.
 
Hi redeloe,
I am not sure we're talking about the same lens. The one I mean is made for the Phase One XF camera system, not for view cameras.

Have you had any further experience with using the Metabones? I am thinking of getting one to try and was wondering if it would work with the Canon 24mm TS-E II? I would take a slight resolution loss if it gave me that equivalent focal length (and the 17mm with full shift). Does this adapter effectively enlarge the image circle so that you would be able to do an "effective" rise of 12mm (in 35mm full frame terms). So 16.5mm of front rise in GFX terms?

If the adapter essentially gave you the same resolution as using the GFX with the Canon 24mm TS-E II and then having to crop (only using the amount where "sharp" rise was able to be recorded) then it would be worth it to me, just in terms of capturing what you see at the time...

Any information would be much appreciated! Would be using the lens stopped down only, around f11 or so.

Alas, I no longer have the Fuji GFX. I did not make frequent use of the adapter, as the native Fuji optics were so good. And I have very poor luck with adapter connections.
