Has anyone printed big yet? How does it compare to the next group down (GFX 50, X1D, 50 MP CMOS backs, D850, Z7, A7r II,III (probably IV), S1r)? It should be a big enough difference to stand out in prints above a certain size - but what size? Is it noticeable in a 24x36" print, which the next group down are already very good at, or are we in only 44" printers need apply territory?

I've used 100mp Phase for many jobs, and would say yes we are in 44" territory.
For me the huge difference came when you enter 60" territory. That holds up very well with 100mp, as shot, un-interpolated.

You do of course get a lot of cropping latitude, but most people try to get the image right from the get-go, not heavily crop it later.

- is the histogram visible on the small OLED screens at the back based on the JPG conversion of the photo and from the RAW file ?

User selectable - you can choose to have that sub-screen showing the histogram.
Many users do that (including me)

what confuses me is I am set to RAW only, so what it is basing the histogram on in that setting, is unclear.
(maybe on some theoretical jpeg histogram, if you had selected that?!)

Edit: In RAW only, it does make that histogram on a jpeg, and then discard it. As the linked article suggests, you may wish to make both RAW + jpeg set to 'fine' for a better 100% screen preview/ focus check. I may switch to that myself.

...
What I liked
- The image quality is very close to what I have been getting from by H6D-100c
- The lenses are great
....
Cheers,
Bernard

The lenses would be my main interest. If i can use them on a Nikon-Z that would make some great TS-lenses.
The DOF of 100MP is an area within the DOF 50MP area and that is already small...
35mm now goes to 60MP and is so much faster, smaller and lighter + so much more lens choice from cheap to expensive...
DOF is not a problem of course with infinity landscape shots... so that is the most preferred use i guess.

One thing to be aware of is that C1 Pro applies as default profile on import the film simulation profile that was selected in camera.

Another additional impression, I am not impressed by the OS of the 100-200 when shooting from a moving platform such as a boat. The Nikons work way better.

Bernard

The 100-200 also has issues at the long end when compared with the Nikon 70-200/2.8E.

The Nikon 70-200 f2.8 E is IMHO the best zoom lens ever designed. Itís probably better at f2.8 than the Fuji at f5.6.

This is off topic, but I am counting days until the availability of the Z mount version that can only be better still.

Cheers,
Bernard

To current owners of GFX100: Is anyone seeing a difference between 14bit and 16bit output?

The Nikon 70-200 f2.8 E is IMHO the best zoom lens ever designed.

I consider the 180-400 mm f/4 to be truly amazing, whereas the 70-200E is just another step in a long march to improved IQ.

I agree that the 70-200E is excellent, but the 180-400 got me to sell my 400/2.8 and 500/4.

Interesting, thanks for the input.

I may have lucky with my copy of the 70-200 f2.8 E. It gives me an Otus like rendering of details at f2.8.

This being said my opinion on the Fuji 100-200 is improving. Iíll reserve my final judgement for a more thorough analysis in a few weeks.

Cheers,
Bernard

Hi,

Data this far indicates that 16 bit output will not yield advantage over 14 bit output. But, I wouldn't rule out it may change with later firmware.

Anyway, if there is an advantage, it would only be visible in rare cases, where you push the shadows to extreme extent.

An interesting note:

It may be that the Phase One IQ 150 may be able to make use of 15-bit coded data. But, it was recently detected that with the latest firmware it switched to compressed 14 bit mode. It seems the issue was missed by Phase One developers and dealers, until a really observant user discovered that files were of the wrong size.

https://www.getdpi.com/forum/medium-format-systems-and-digital-backs/66550-iq4-recording-wrong-image-format-14-bit-instead-16-bit-ex.html

Best regards
Erik

Has somebody else noticed that auto ISO uses ISO200 even when ISO100 is set as base value and there is enough light for the minimum shutter speed?

It makes auto ISO incompatible with the quest of maximum image quality the camera was designed for...

I hope Fuji will address this quickly.

Bernard

I read on Diglloyds blog:

Play-Delete resets lens focus.  ... is that correct? Hope not.

Bernard,

Mine does not do this.  Make sure you have the DR setting at 100.  If it is 200, 400 or Auto the camera will default to the ISO required for that function.  See page 110 in your manual.

I shoot raw + Super Fine jpeg for exactly this reason.   And... the jpegs make terrific targets for comparison when processing.  Often, the jpeg w/ some VERY MINOR adjustment is equal to or better than what I can achieve.  Fujiís jpegs are famous for a reason, Iíve found.

Has anyone used continuos autofocus and tracking and the GFX100? How were your results and what were your settings? Comparison to say a NIKON D850?

I havenít used a modern mirror less in a while, however, I would say the gfx 100 is quite good and one should not forget that we are talking about mf. Phase One and Hasselblad canít even dream of these AF capabilities.

Bernard,

Happy to hear that was it, rather than some bug or other in the software!

Bernard:
"The image quality is very close to what I have been getting from by H6D-100c"

Can you quantify that is some detail?

Congrats to Jim Kasson (often contributes here) who finally has his GFX-100, hurrah.

His blog provides many technically details insights here

Including:
the dual gain bump is at 500iso, not 640 or 800.
the sensor is GBRG array rather than the classic RGGB
the Phase Detect AF pixels are positioned 18 pixels apart over Red positions.
very little LoCA shift, at least with the 110mm/f2 lens.

Some of his posts are of detailed technical interest, others, like recognising the 500asa gain bump, are relevant to regular use of the camera. Maybe Jim himself can emphasize any essential details, but my thanks for his research.
