I've completed tests for LoCA and focus shift on axis.

There is very little -- actually, unbelievably little -- LoCA.

There is a fair amount of focus shift. You'll want to focus at the taking aperture at f/2, f/2.8, and f/4. After that, you can focus at f/5.6.

The lens is unbelievably sharp.


I did some visual comparisons vs the Otus 85/a7RII combination this morning. I'll get them up sometime today, and I'll reply to this thread with a link.

Thanks Jim for taking the time to put together this awesome content for all us people on the internet!

Just checking... if you use AF, when you half-press the shutter (or AF on another custom button) the GFX will AF at the taking aperture - to eliminate focus shift, i.e. the lens momentarily & automatically stops-down to the taking aperture when auto-focusing.

Focus shift might only an issue if focus is set to manual focus?

- as I say I'm just checking! - as I'm not sure; but I think the above is correct about AF.

That is my understanding as well. However, with the systematic AF errors with some lenses at some apertures, you need to resort to MF more often than you might think.

I have completed a series of quantitative AF tests on the 110, and the computer is crunching the data as I write this. I threw something else into the mix in addition to my one-position AF mode: the zone mode. We'll see if there are any differences.

When I did the comparison with the Otus 85, I did an aperture series with the GFX/110 using AF, just to see how it would come out. In no case were the AF captures as sharp as the MF ones. You wouldn't call the AF ones soft if you had nothing to compare them with; they just weren't up to what the lens can really do when focused properly.

I finished the 110/2 AF test:


  • Performance is the best of the four lenses I've tested so far.
  • Using zone mode removes the unstable region at f/2.8
  • I'm probably going to have to go back and retest the other three lenses -- 23, 63, 120 -- in zone mode to see if that fixes their af problems.

Have you read about Lloyd Chambers's continuing nightmare with this lens? (I think it is the 3rd sample a dud)

https://diglloyd.com/blog/2017/20170702_2202-FujifilmGFX-110f2-aseries-FaceInBoulder.html
Sounds like bad luck in the extreme. I have four GFX lenses: the 23, 63, 110, and 120. They are all very well assembled.
One would expect FujiFilm to make sure the lens was good, especially when shipping it to a respected reviewer who has been previously disappointed. This doesn't give potential new buyers confidence. I'm glad you haven't experienced problems.
Lloyd's lens could have been damaged in shipment. I think that the 110/2 is more fragile than most. When you roll the lens end to end, you can feel something heavy shift inside. That is probably the lens elements that are moved to focus the lens. I suspect that the lens uses a VCA for focusing and does not park the elements when the camera is turned off. If my guesses are right, this lens will need to be handled with care.

In his prior experience with two other GFX 50 bodies, and also with the 63mm and 120mm lenses, he reported "erratic and highly variable auto focus," noisy focusing motors, and the need to magnify to ensure accurate focus. If this equipment is so fragile and prone to focus problems, it hardly qualifies as professional level in my view. I had been considering it as a serious upgrade candidate, but not any more. Again, I'm glad your components have worked out well for you.
I assume Lloyd Chambers (diglloyd.com link above) didn't buy his GFX and set of lenses - they were a loan from B&H.

B&H wouldn't loan anyone a brand new camera + lenses, they'd either be shop demonstration units, returned units, or perhaps open box. I suspect the GFX body he received had been returned to B&H after it had taken a tumble (maybe from a great height in bag). The returner didn't admit this, they just said the camera wasn't to their satisfaction. B&H checked it over, looked ok, so put it back on the conveyor belt of OB items (there are other scenarios, a fall from a 6m high B&H central warehouse shelf, from top of the delivery truck etc).

Then the B&H packer gets a note on his computer to send another GFX to Lloyd, they send the only returned/OB unit on the shelf - the same unit goes back to Lloyd.

The GF110mm was probably in the same scenario that took the fall. The GFX body + GF110mm 'fault' seems more likely to have occurred after it left the Fuji factory in Japan.

Ok so now Lloyd has been loaned a third GFX (probably actually the second if the above is true), this is the kind of GFX that all other GFX owners have - one that hasn't been involved in an accident. BTW this GFX is working fine for Lloyd.

He's also reviewed the GF23mm, this is what he says:

"The GF 23mm f/4 turns out to be rewarding, with a superlative performance. I have no hesitation in giving my highest recommendation to the GF 23mm f/4 —this is the lens that anchors the system in my view."

Sometimes one has to absorb things that are wrong and sort them out directly with the party involved. If someone bad mouths me (maybe unintentionally), I don't then announce that to everyone (and so magnify the situation and make it public), I have a private word with that someone [i.e. B&H or even Fuji, but more likely B&H). It's fine if LLoyd wants to report experiences immediately on his blog, but we the reader should read between the lines, not overreact, or at least wait until Lloyd has balanced his views.

The only 'negative' which I agree with him about it that the 63mm is more noisy to focus than most would like; for me this is 1 negative among 100 positives. There are many rumoured lenses to be added to the GF roadmap, the majority I expect will have quiet internal focusing linear-drive motors that users of the 23mm and 32-64mm are currently enjoying.

It's sad that Lloyd's hyperbole puts people off buying perfectly good camera systems.

He's a drama queen - and that's a deliberate ploy to drive his site subscriptions. In other words, he always has an agenda, and that's not good for the rest of us.

You should instead look at Jim's scientific testing, and his real world analysis - you'd be in a much better position to make an informed decision.

Why would a mirrorless camera, even if dropped, have serious AF problems? AFAIK there are no mechanical parts involved. Seems to me, it would have to be extreme damage to the electronics, not just from a 6' fall of a boxed product from a shelf.
Fine, if you have a MILC drop away,
but there is genius, care and delicacy in there - these units pack a lot of tech in,
I'd rather not drop it...

or the GF110mm lens...

That's a strong positive, given the fact that it's the only UWA lens in that range currently available for any MF digital camera AFAIK (notwithstanding discontinued Pentax 25mm). I have no doubt of FujiFilm's optical design prowess. I had a Fujinon SW lens for 4x5 that was nearly as good as (in some ways equal to) my Schneider and Rodenstock optics. However, the mechanical integrity and durability of the focus mechanism of these large, complex lenses may be fragile and unreliable.
Fuji were making AF MF lenses for Hasselblad for many years, rock solid, better than their previous Zeiss.

Lloyd had lots of trouble with GFX camera bodies and lenses,
you mean the one he had on loan from B&H - that probably had been returned by someone else? Try that yourself, ask for a loan camera from a camera seller; then wonder why there might be something wrong with it.
so I think his "drama" is warranted. This is probably an issue that needs to be sorted out by the manufacturer, not by reviewers or retailers IMO. IOW "not ready for prime time," or at least one can expect to need frequent servicing as with a Lamborghini automobile.
Maybe you should play devil's advocate with yourself, buy a Fuji, maybe yes the GFX, I reckon you'll do a 180 on your views and those of Lloyd. Maybe it's just a money issue with you? - I don't know, but the GFX and it's lenses are remarkably good.

Please listen also to us - the other photographers who use the GFX, it's the 90% best camera I've ever used, and the lenses 100% the best I've ever used. I say '90% the best camera' as there are a few niggles with it, but still on balance I wouldn't swap it for anything else, not an A9, not a D810, not a Phase1 with Schneider Glass, not anything; it overstands everything.

All I can say is just try a GFX with GF23 or GF32-64mm, or any GF lens, not just in a shop, but over a few days out and about, then report back.

My experience with the GFX does not mirror what Lloyd has written in his blog. This is not a difficult camera to use providing you are methodical in your approach. Unfortunately people can end up with bad samples, for whatever reason, but he's the only person I'm aware of that has had such a torrid time with this system. Read into that what you will ....

I hate to bring up the mundane but Fuji does theirs for $1700 less.

I have great admiration for FujiFilm's engineering expertise, although evidently there have been a few missteps.

Lens capability is central to my selection of what may well be my last system upgrade. My expectation for, and the implied promise of the GFX, being one of the earliest mirrorless MF cameras introduced, was that it would have advantages that other MILCs have (such as Sony A7x) -- particularly the use of adapted lenses. Another one of Lloyd's revelations has been that this is unlikely to work satisfactorily, citing ray angle difficulties caused by the thickness of the sensor cover glass, even with lenses that have a sufficiently large image circle such as T-S / PC lenses from Canon, Nikon, and Hartblei.

That is a huge blow, and I don't see much chance of FujiFilm building compatible T-S lenses for the GFX due to the extremely limited market. The autofocus debacle and the high price on top of that kills it for me. For architectural shooting, Nikon's new PC Nikkor 19mm lens now tips the scale toward Nikon D810<, in addition to their superior Sony sensor which the Canon cameras thus far cannot match.
