This thread over at Getdpi may answer some questions, that 23 mm Fuji renders very well with little distortion

I think the 23 or the upcoming Laowa 17mm will be my first Fuji GFX lens that isnt adapted

Given my resolve to adapt 3 trusted TSEs to my 50s, I really should not have read Danny's post ...

p.3 #5 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


For anyone who needs GF quality tilt-shift lenses with the full-blown Zeiss look, I'm trading / selling these rare set of Hartblei Zeiss exotic lenses (based on the latest iterations of Hasselblad Zeiss glass, with updated digital coatings and made in Germany tilt-shift sexy metal Superrotator barrels)

https://www.fredmiranda.com/forum/topic/1620421

I've used them back to back with the 23, 63 and 110 GF glass, on my GFX 100 and that Zeiss glass still kicks ass (stopped down a bit). But my work is taking a different direction, and I can't afford to keep everything.

Ok, later edit from me. The Zeiss tilt-shift glass is not going anywhere, it is still irreplaceable - at least in my workflow (correcting verticals on the 23 messes up the resolution and framing, completely) . I must save some more for additional GF glass. I'm so glad I shot my lenses today in London

p.3 #8 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


Need to do some side to side shots with my 23mm f4. Here is a quick one with 24mm TSE-II using techArt adapter. I didn't press any magic buttons on TechArt. To me it seems better than what I see poster here but I could be wrong. Taken at F8. I don't know who much shift I used. I had just gotten the lens when I took this and my first forays into manual focus too.

Here is a quick test comparing my 24mm TSE-II with the 23mm f4. MF was harder with the 24mm TSE-II. For 23mm I used smallest focus point and AF. Kitchen paint work was put on hold due to covid.

p.3 #10 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


Good video showing GFX adapted to Canon TS lens. Does not speak to the 23mm but the 23 does not shift so its not much use to me.




shift lens should adapt well to GFX because it has a large image circle.Same guy video that show laowa 15 4.5 shift being better iq than TS17 with limit of 8mm shift.
Slightly better edge sharpness with less contrast and more flare - but I am not sure that it would be the same at infinity.





[The GFX100s got me interested. I am mostly about landscape.With some bears, wolves, and moose. I am interested after the GFX 100s because I have been waiting for Canon no aa, 90mpx R5SR - if it ever comes. Maybe I should stop waiting if the GFX is able to use my shift lens. Close trees and big mountains need UWA shift. But I like 16x9 format so I am not sure about 4:3]

The GFX and 4:3 is great for trying different aspect ratios, the 100S has 77mp in 16:9 mode.

Probably you would not even see that part on 35 mm full frame camera. So no surprise that Canon is weaker at the edges (lens is designed for 36mms wide sensor and not for 44mm).


Just intuitively, a ts24 is likely to have more field curvature when viewed at medium format vs full frame because the cropped version (ff) will not extend as far and avoiding some of the field curvature in the picture. However the distortion is quite low on the ts24v2 so this is not likely to be dramatic. Thus using more of the image circle (medium format) will reveal more field curvature if it exists.

The other thing to keep in mind is that the ts lens are very sensitive to off centre tilt. Eg even if its set to no tilt it can be slightly tilted and this results in poor corners. And sometimes the itlt is on when marked at no tilt.

But the most important thing to consider is that the field curvature of a lens can be concave or convex or flat - or even worse because you can work with convex or concave by choosing your focus spot - moustache shaped. What looks flat close in (focussed well edges and centre) really implies convex field curvature because what works for close will tend to be convex (eg the lens to edge is further than the lens to centre) . And what works well for infinity will tend to be flatter (edge to side is similar to edge to centre depending on the scene). Thus a good close in lens is not necessarily a good infinity lens.

A good article that gives a possible explanation why a very good lens TS24 might not do as well depending on whether close focussed or far focussed.
https://petapixel.com/2016/12/21/field-curvature-tricky-problem-photography/
https://www.lensrentals.com/blog/2020/01/practical-use-of-field-curvature-wide-and-telephoto-primes/

I note that further someone has posted TS24 at a further distance and it looks much better on edges.

So the posted samples may not be definitive - maybe the ts24 works better than 23 at infinity or maybe ts24 copy was not set well or maybe the 23 was just better.

Because the ts24 certainly tests well on the canon https://www.opticallimits.com/canon_eos_ff/603-canon24f35tse2?start=2

This is a critical factor for me in being interested in fuji 100s because I shoot mountains at infinity with nearby trees and the 23mm will result in bent trees - no acceptable.

[GF 23 has mild moustache field curvature per the posting on https://www.dpreview.com/forums/thread/4470565#forum-post-63731429] eg at a close in distance (not infinity) the centre has similar focus to the edges but the middle does not]

One of the most requested lenses for the GFX has been a tilt shift wide angle lens (along with wide angle zoom and longer telephoto zoom) so they may end up providing a native solution. Fujifilm had Fujirumors do a poll like a year ago and the two most requested tilt shift lenses were 21mm and 30mm. Someone posted a link the other day on another forum.

Fujifilm has stated in the past that they would make the whatever lenses their customers want so I think it would be reasonable to think that a native tilt shift could end up on the roadmap the next time they update it. It's currently empty.

The link.

Thanks

Obviously a shift/tilt fuji 23mm with much wider glass theoretically should be better (larger image circle) than the ts24

but it is still not clear to me that it does not already exist in the ts24 or ts17 or ts45 - the sample may have just been focussed on the wrong place for a close in shot - eg should have focussed off centre a bit or middle.

Or maybe the ts24 only works well for infinity shooting and the GF23 may be works better for close in.

You're welcome. I'm interested in but don't do much with camera movements but I do know that the desire for options for camera movements has been pretty constant since the GFX came out; some use adapted FF lenses, some pine for native solutions and others even mount their GFX like a digital back on view cameras like the Cambo Actus or Toya setups. I wouldn't be surprised if they make a tilt shift lens. But I know that Fujiflm managers were stung after they made the 200mm f/2 prime for the X series and it didn't sell well despite the fact that people said they would buy it. I wouldn't be surprised that after going through the film implosion if they are sensitive to introducing even a single lens that is a flop. And a tilt shift lens seems like a specialty lens.

I have looked over your samples at high resolution on Flickr that you linked to and its hard to choose which is better fuji 23 or canon ts24. They are very close.

Thank you for posting.

Thanks Scott. I am still hoping that Fuji comes up with a native TS option that would be great. It will be expensive but not like what some other think. I think it will be $3000 at most.
