That's very cool. Did the adapter have a tripod mount? I'm looking at the Kipon Hassy V to GFX shift adapter and the photo makes it look like there's a tripod mount, but it's not listed in the specs. If there is one on yours, is it on the lens side of the shift mechanism or the camera side? Finally, did you have to flock yours to cut down reflections? That was my only complaint about the Kipon shift adapters for the e-mount.
Thanks in advance.

Brad, the Kipon Hassy V to GFX has a tripod mount positioned in front of the movement, making it a very good option for panoramas as it avoids any parallax issues.I returned my copy though due to light leaks and poor lens release knob. I've heard others having the same issue but it might be sample variation or fixed by now.

The Kipon Tilt/Shift adapters have issues of build quality and lightleaks ? Thats very bad news. This is so far the only way to get T/S on GFX.

Expensive yes, but there is the option of the Cambo Actus GFX which will offer much possible for T/S as well a selection of many lenses. This includes the option of using Shift lenses from the likes of Leica R, T/S lenses from Canon EF and Nikon, MF lenses from Mamiya, Pentax, Hasselblad, Contax, MF digital lenses in barrel and shutter, LF lenses and digital lenses, and Enlarger lenses. Additionally, Cambo has now offered the add on Tilt kits which will offer additional tilt and shift options for the Cambo Actus cameras.
I use a Kipon Olympus OM to Fuji X tilt-shift adapter. It's far from perfect. I had to flock it to control internal reflections; I've had to flock every adapter I've used, tilt-shift or not, because they're all too shiny inside. I also had to add a thin layer of metal tape into the shift mechanism of the Kipon adapter to tighten things up a bit. This particular adapter also has a design flaw where if you shift past 10mm it actually exposes the opening (but I never shift past 10mm so it's not a problem). Aside from these minor irritants, I have not experienced light leak issues and I often make longer exposures.
The Mirex adapters I used to use -- while built more precisely than the Kipon -- had a similar potential for light leaks simply because of the design. Thibauld Roland (who does long exposure photography) described the problem here: https://briansmith.com/long-exposure-photography-thibault-roland/ He just drops a cloth over the thing when he's making long exposures.

Besides, anyone tried the new Voigtländer Nokton 50mm f1.2 on the GFX and can tell us how well it covers the sensor ? That lens has really dreamy Bokeh and 50mm would be very much a 35mm equiv on the GFX sensor.
Actually, it would be more like a 63mm.
When you are coming from full frame you have to divide not multiply.
However, I, too, would like to know if the cv50mm f1.2 covers the GFX sensor.
As I mentioned earlier in this thread, the cv40mm f1.2 covers fairly well with very little vignetting that can easily be cleaned up in LR and significantly diminishes as you stop down. I'm hoping the cv50 will do better.

No, it would be more like a 35mm f/0.9 on FF 35mm if you crop to 4 X 3 or squarer. For larger sensors lenses work like a shorter focal length with a wider aperture than they do on smaller sensors. Just like a 50mm lens is like a 75mm on APSC, it is like a 35mm on 44 X 33.

I haven't used the CV 50 f/1.2, but I do have and very much like my Canon FD 55 f/1.2 Asph on my GFX. It is quite possible that that CV 50 f/1.2 will cover the sensor, but it might not as well. I would love to see someone try it.

Based on a few posts in the GFX facebook group, the new 50/1.2 covers quite well, better than the 40mm, and is sharper to boot.

Your math is off. You multiply, always.
Also, the CV 40/1.2 has more than "very little" vignette on the GFX ... unless we're somehow talking about different lenses. It's mostly correctable, but at f/1.2 it's a whole lot of vignetting.

Yay !!! Awesome.

I fail to understand what you are trying to say ?
The Fujinon GF 45mm f2.8 is a 35mm equiv on GFX. On a full frame camera it would be a 45mm equiv, because full frame is the reference point, so absolute focal length = equivalent focal length.
The Voigtländer 50mm f1.2 is a 40mm equiv, or still close enough to a 35mm equiv, on GFX. On full frame its a 50mm equiv, again, since full frame is, again, the reference point.
I'm not trying to find an equiv for a 50mm on GFX, which indeed would be around 62mm ... I want to use the 50mm on GFX.
Correct! Mea Culpa.
But, I'll let my post stand as a warning to myself and others to think first then post especially before you go to sleep.
I wish I could say I was drunk, but no such luck.
Anyways, thanks for clearing this up.

Keep in mind when comparing focal lengths of the GFX to FF 35mm aspect ratios matter. FF 35mm is a 3 X 2 aspect ratio; 44 X 33 is a 4 X 3 aspect ratio, so when comparing focal lengths on the two formats you need to decide if you want the photos to look alike or not. Assuming you want the photos to look alike you can either crop to 4 X 3 (or a squarer aspect ratio) or to 3 X 2 (or a skinnier rectangle). 50mm on 44 X 33 if you crop to 4 X 3 or squarer will give you a very similar look to 36.5mm on FF 35mm. If you crop to 3 X 2 or a skinnier rectangle then 50mm on 44 X 33 will give you a very similar look to 41mm on FF 35mm.
SMC Pentax-A 645 35mm f/3.5 lens adapted to the GFX 50S with Kipon Tilt-shift adapter.
Lens is sharp with good micro contrast. When shifted, the corners start to suffer a little, but remain acceptable to me.
The lens has distinct mustache distortion.
Regarding the Kipon tilt shift adapter- can the tilt section and the shift section be rotated with respect to each other, or are they fixed and both rotate together, like the Mirex/Canon adapter? I can't find anything in the specs and haven't seen mention of this detail of operation.

Have you experienced any problems with light leaks? I sent my Kipon Shift adapter back due to leaks and the fact that it would not lock the lens in place. I’ve heard orher people had the same experience with the shift version. Orher than that - great idea.
