Then you must be using it in high speed 12 bit mode. I have two 100s's and the new body and I don't see a whit of difference between the two models. If the new one focuses faster, the improvement is so small that it has not been noticeable to date. And I'm not really sure how you can judge readout speed simply by taking photos, and again, if you're shooting in single shot 16 bit mode, there IS no difference.

The main effect is the AF Speed which is relying on the times the sensor can be read is now up to the challenge of action photography. Did a gymnastics German major league event yesterday ans while of course it is not as fast as my Sony a1, my test shots showed, it is now absolutely useable for that. And as Jim points out in the video, most of the shots are of course with ISO 3200 and over - so the information quantity doesn’t really matter anyway.

But that is ONLY happening in high speed mode and has nothing to to with ISO anyway, so if you're shooting in that mode then maybe you see a very slight difference, but not in the type of shooting that the vast majority of do, for instance, when I'm shooting people in the studio at base ISO and in single shot mode.

Well, what he wrote and even Jim is trying to let people understand is that when shooting fast, iso will be high making the difference between 12, 14 and 16 but zero. The is no purpose to use this shooting mode in a studio except when you are having action and even then high iso cannot be avoided.

If that's what he meant, it's certainly not what he wrote, and I can certainly imagine scenarios where you might be shooting fast at base ISO. Again, it's back to the misleading marketing from Fuji where they'd have you believe that the "improved" dynamic range applied to more than just one ISO setting, well two if you count 40, and that the faster readout applied across the board, which is most clearly does not. It's fine to cherry pick your specs if it makes you feel better but it doesn't change the facts on the ground.

DId you actually watch the video?

And could you point us to a document where Fuji has indicated what you accuse them of?

I could not care less of what Fuji wrote, I'd do not even read it. I tested all gfx so far and the 100ii is the only one with useable AF for my case.
If you want and need tru best for fast action, MF is probably not the way ti go anyhow. I pick my z9 for that. Others a Sony or canon.

What Fuji writes does matter, and it matters because a LOT of people out there, maybe not you, but a lot, actually believe what they say, and, while, it's technically true, it's only true for a very narrow subset of users, so if you want to get the most out of your gear, you need to know what the data really is and how it applies, or, y'know, you can keep your blinders on in ignorant bliss.

Look again at what they wrote - I believe it's more a matter of what you wanted them to have announced / your interpretation plus what some influencers in their ever sensational way interpreted it. At least I can't find any document or material where they indicated high speed readout at ISO 80 or anything similar.

I have to agree that the AF of the GFX-100II is significantly better than that of the 100s, i own both and the difference is very obvious.

The II is still very far from my Z8/Z9 but the range of situations in which it can focus on moving subjets has been expanded considerably.

Overall, the II is a much more responsive camera that is better rounded in most aspects.

In the mean time, here are a couple of images captured with the GFX-100II.





Cheers,
Bernard

The 100II is noticeably faster than the 100S in AF. Maybe the new processor?

Fuji loves their place in the mini medium format world.

When will they get ISO 25 and lower with the attendant sharpness gains we had with films like Kodachrome and Tech Pan?(even if TechPan was basically a high contrast film - it was great in very low light/long exposure conditions)

Instead we keep getting stratospheric ISO's. Great for some things but few use them so it is mainly a marketing tool.

Get us some ultimate image quality Low ISO settings, please.
