p.1 #1 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


I received my GFX50S last week, and have begun doing some initial tests with my lenses and a Techart adapter.

The Canon 24/3.5 ii tilt-shift looks very good, and easily covers the full image with room to spare. On the other hand, I've read many glowing reviews (and no complaints, IIRC) for the native 23mm. I've not had a chance to compare the latter. Has anyone here done a direct comparison, and if so, have you found the 23mm superior? Since I already have the Canon and it works well, right now I'm not seeing a reason to go after the 23mm unless it's decidedly better. TIA.

p.1 #2 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


Hello Danny,

I do not have an adapter to test the 24mm TSE with the GFX but I do have the 23mm and it is a great optic. I haven't had any issues with any of the GF line of lenses. Some focus faster than others but optically I don't think there is a bad one in the bunch. Since you are a long time 4x5 film shooter and now digital with the Sony, Canon and GFX, I'd love to hear your thoughts on your current process.

Welcome to the Fuji GFX line. I hope it is a winner for you.

Patrick

p.1 #3 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


Hi Patrick,

Thanks for your note. It seems that all of the GFX lenses have great reputations; so far I've only done a few tests with the 32-64, although I also ordered the 110 this morning and I hope to give both of them a better workout on Friday.

I'm sure the 23 is great - I don't think I've seen anything negative about it. The problem (if it's a problem) for me is that the Canon 24 also looks excellent on the tests I've done, and it has the benefits of (moderate) movements and proper manual focus, and the question is whether the excellent 23 is more excellent than the 24!

I have a few friends who have the 23 (but haven't used the 24)...it may be a situation where I need to get in the same place at the same time as one of them so I can do an actual one-for-one comparison.

Thanks for the good wishes...I haven't had much chance to use it yet, but I think I'm already seeing that it's going to be the best camera I've ever used.

EDIT - just reread your post. Did you mean that you're looking for thoughts re: my conversion from 4x5 to digital? I'd be glad to post some impressions if so.

Yes, as an old 30 year film guy myself I'd love to hear your general thoughts on how the migration from 4x5 film/scanning to digital capture has worked out. I still shoot some 6x6 occasional for B&W. Just curious to hear your take now and the fact that you are dipping your toe into the MF Fuji GFX system is of interest to me.

p.1 #5 · GFX 23mm lens vs adapted Canon 24/3.5 ii tilt-shift


OK, I'll condense as much as possible to avoid writing a book! It was a somewhat difficult transition, as you might expect. I shot primarily 4x5 (Ebony) and 617 (Linhof and Fuji), but also medium format, mostly a Fuji GX680iii. I did have a DSLR (original Canon 1Ds), but I couldn't bring myself to take it seriously and only used it for casual shooting. I didn't expect to quit film, but closure of my local lab combined with ongoing back problems (not helped by all the equipment weight, no doubt) led me to look into a Canon 5DSR in 2015. After doing comparison testing for a couple of weeks, I decided to make the switch, sold all the film equipment, and bought a 5DSR plus a load of Zeiss lenses with the hope of getting as close to drum scanned 4x5 quality as I could.

After a few months, the Sony A7RII came out, and I decided to get one as a backup to the Canon; I thought that a backup that could do different things was a good idea, and since it could use my Canon mount lenses, why not? Well, I immediately discovered that I preferred mirrorless by a huge margin, and the Canon went into the closet as the backup until I finally sold it early this year. Later I added an A7R and had it converted to b&w infrared, and early this year, I got an A7RIII as the primary camera and made the A7RII into the backup when I sold the Canon. As of last week, I now have the GFX50S as primary camera; I'll use the A7RIII for those lenses and occasions that don't work well with the Fuji, and the A7RII is up for sale.

Probably like many large format shooters, I have a huge dislike of 3:2 aspect ratio; the Sony's lack of varied ratios has been a major thorn in my side, even though I like it otherwise. That's the main reason for getting the Fuji, although overall I'm loving it already. It's brilliantly designed and great in use, and needless to say I love the built-in aspect ratios, especially panoramic (I do miss my 617 cameras) and the native 4:3 ratio.

Hmm, what else?... Moving to a tiny viewfinder from a large ground glass has been difficult for composition, although I'm fairly well used to it now. Another negative is the lack of movements, although that's been less problematic than I expected. Positives include a whole new way of seeing many things, especially the largely out-of-focus and wild-bokeh flowers that I never did with film. And instant feedback, no film cost, no need to drum scan film, and other things are nice too. Not to mention the astounding dynamic range that one has nowadays, compared to 4-5 stops with transparency film and 8-10 with neg! Overall I'm happy I made the switch to digital; I think the only thing I've really missed has been the ease of single-frame panoramic composition and shooting, and now the Fuji solves that problem.

Thanks! Exactly what I was looking for. I wonder why it didn't show up when I searched?

Very good to know. I did a bit of testing indoors (still no decent weather to go out) and the 24 does look excellent. The 17 is good, but less so than the 24, with slightly softer corners. Both are optimum at f/11; at f/16, edge sharpness was slightly better (probably due to DOF), but overall sharpness slightly less from diffraction. I didn't try intermediate apertures, which may be worth a look next time.

It’s incredible how sharp the GF 23 is at f/4, and I see little difference stopping down save for a little less vignetting at 5.6. Quite a bit in focus using 5.6 as well.

I think the forum search engine is down. I had to use Google with the “fredmiranda.com: term here” thing. I knew the post was here having read it a while back.

There are always weaker and stronger lenses though.

Yes, there are always weaker and stronger lenses to buy but just making a point that I don’t think there is a bad optical design in the GF line up.

Yupp.

My point is just if I spend this much money I still prefer to pick first the ones that are amazing over those that are "merely" very, very good.

Fortunately, in this case, that would be the lenses I'd prefered to pick anyway (45/2.8, 250/4 OIS, 23/4).

I have both the 23mm and 24 TS-E but have never done a real side by side comparison! I only got the 24 TS-E for architectural work, and never take them both on assignment. But they both seem super sharp on the GFX.

Maybe it's okay to contribute a GF23 image?

Anyone know how much of the tilt//shift action with the 24 II is available on the GFX before you run out of the image circle?

Apart from sharpness, did you ever notice any difference in color rendition and contrast? In a way, the 24TS-E can fill 2 slots in a system: wide angle and architecture... kind of cheap if you look at it that way. It is also wide angle where I would miss AF the least...

The lens has an image circle of 67.2mm. So if you're using the GFX-sized sensor in 4:3 aspect ratio, and you're shooting in landscape, you can shift 6.6mm to either side, and you can rise/fall 8.5mm. In 3:2 orientation, shooting landscape, you get the same shift (side-to-side) but a bit more rise/fall (10.2mm). These numbers describe the point at which the corner of your sensor area hits the edge of the image circle.

Caveat: real-world performance at the far shifted edges tends to suffer a little or a lot with shift lenses. I don't use this particular one so can't comment on it. Anyone who uses this lens on full frame could comment on how image quality does at the far shifted edges with the maximum shift (12mm on full frame).

Never really did a comparison as I process my architectural shots differently than my landscape. I will try and post a comparison, but I am in Europe at the moment and only have the 23 with me.

I believe I try to keep under 8 when shifting.

I was testing lenses a few days ago; I didn't run out of image circle using 10mm rise (horizontal format). I'll get some samples posted soon.

I read somewhere that the Fuji 23 is less prone to "stretched" corners than most wide lenses. Seems to be true judging from samples I've been looking at. Anyone agree/disagree? Stretching is definitely present with the 24 tilt-shift.
