I'll use this thread for posting some example shots from my testing.

Just remember, not everything I photograph is to test critical sharpness etc.

This shot was taken hand held [ISO 3200 1/50 ~F6.7 IS set for 17mm on the GFX100S]

Processed in DxO PureRAW then ACR in PS

Some smaller ones to give a feel for coverage with mostly full vertical shift

Hope that gives a good feel for 17mm with shift on the GFX...

Keith,

thanks for posting. How do you think it does against the Canon 17mm TSE shifted? It seems to me the corners are not as smeared on the TTA.

Not properly tested in daylight, but my feeling is that these images are better in the corners - but 'only' 8mm shift - I may well find that the alignment of my TS-E17 has gone a bit after 18 years use ;-)

If we get a clear night I'll see how it does with stars...
 
Thanks for the samples Keith. This is a remarkable performance, especially considering the modest asking price.

A PureRaw processed one, but the top shifted corners definitely feel better than I'm used to getting with an adapted TS-E17 [TBC!]

Well, I went ahead and ordered one. Will be comparing it to my 17mm TSE. In the end will keep the one with the better IQ. Hopefully it ships soon as I have a trip to Costa Rica in a month and the 17mm tse is my most used landscape lens.

Good on you. Taking one for the team! ;)

I'm looking forward to your report. Keith's samples look very promising.

his samples pushed me over the edge to buy it.
 
Nice one Keith. ☕️

Tell you what would be neat, Fuji could implement firmware Gfx update a more sophisticated implementation of Olympus Keystone in camarea vertical horizontal alightment with any lens, to mimic a proper TS in Gfx camera, as well as applying this to Gfx RAW.

At the moment Olympus Keystone in camera is basic just vertical horizontal, with any lens, also only applies Keystone to only jpeg.

Here on 2014 Oly E-m10 mkii Keystone with any lens, in camera vertical alightment. https://thedigitalstory.com/2016/09/keystone-compensation-on-em10-mark2.html

Here on 2015 Oly E-m5mkii Keystone with any lens, in camera vertical alightment. https://pixelcraft.photo.blog/2019/11/01/in-camera-keystone-compensation-olympus-i/

Photography after all is interplay of light alongside perspective.

It would be nice to see direct comparison test images shifted the same amount with both lenses. Even if the TTArtisan is sharper in the corners it would be interesting to see if you miss the extra 3mm of coverage by the TS-E.

John,

One of the things that pushed me to try the TTA is that on the Canon I rarely shift past 8mm due to vignette and very soft corners. The Canon looks good up to about 8mm.
 
This may have been covered in a thread I missed, but just to confirm: using the vintage view-camera terminology, in the GF mount this lens has rise/fall and swing, but not tilt or shift? Ha ha, funny for a T/S lens. In the other mounts the rotation is at the back of the lens like (some?) Nikon T/S lenses? Meaning no rise/fall combined with tilt.

I must have missed the email that TTA sent me asking if I wanted swing/tilt on a 17mm lens. I don't, particularly. I hope TTA reads this and modifies the GF mount to eliminate tilt/swing and enable horizontal shift.

Whinging out of the way, the shifted corners sure do look better than the Canon TS-E 24mm red-ring. Thank you, Keith, I think.

Nope - it would take a wholesale redesign of the lens. The G mount version is just shorter because of the longer flange distance.

The lens on GFX [in landscape orientation] has up/down shift only

The tilt is limited to left/right tilt

The two axes are fixed relative to each other

The G mount version of the lens does not have a rotating mount

The rotating mount is available on E/Z/RF/L mount versions of the lens, this means the shift can be in any direction, but the tilt drectionis still at 90º to that.

So, this is much like the movements on the old TS-E24 / 45 / 90, although they could be modified to shift the tilt axis by 90º - something I did with my TS-E 90 but not TS-E24 [mk 1]. The newer TS-E 17/24(ii)/50/90/135 all have tilt and shift axes which can be moved relative to each other.

Having swing only would be weird.

If I ever wanted to use a 17mm lens on my technical cameras, I'd get one of these, remove as much of the rear as I could and still have the aperture ring work properly, bolt it to a board and be on my way. I did that with the Samyang/Rokinon/Bower 25/4.5 tilt-shift (which sadly is only OK).
 
If I were looking for this lens on GFX, I'd buy the EF version, which can rotate, and use an adapter so I could shift it up/down or left/right. I would prefer stitching for 33mm x 60mm. I could also use it on both systems.

Unless I am missing something.

That would be the TTA 50/1.4 tilt lens

Tested it a while ago - it is ;-)

A fair bit can be removed, see the view at

Ah too funny. Too much jumping around here. Probably thinking about the Laowa 200/2 that they oddly had to release in EF.

I do see what you mean by it's mechanical shortfallings. For architecture on GFX I would sure want to use the camera vertically and likely shift up.
