Question for people knowledgeable about the GFX system, and the GFX100 in particular.
I am in the process of reading the manual, where I am sure these information can be found, but I would appreciate if those in the know could speed me up on the bit on the following aspects:
- is there a way to jump straight to 100% zoom when shooting?
- is there a way to jump straight to 100% zoom when reviewing image?
- is there a way to display a compas in the viewfinder information about how level the camera is?
Thank you.
Cheers,
Bernard

On the GFX 50s, you can double tap the LCD, like on a P1 back, this brings you to 100% view (on the 50s I always felt it was an overzoom past 100%),
You can expand/shrink the LCD like on the iPhone (assume the 100s allows this)
If on the EVF you could push one of the dials, I believe the rear one to zoom to 100%, I don't use the EVF at 100% very often due to same issue overzooming.

Thanks Paul.

Pushing the rear dial should zoom in. How far depends on the last setting. (You can change the zoom rate by turning the wheel after you pushed it)
Same should go with image review. (As Paul said double tapping works as well when enabled.)
If you mean a digital spirit level, than yes you can. You can map it to any button or lcd swipe gesture. It should show up on the LCD or EVF when enabled.

One more thing. You can zoom in to 100% in LV, but only to 50% on image review. You can go to 100% as well but for that you would need to shoot raw+JPG

Thanks Christopher!

I receive my camera today but from what I have read so far it looks like Fuji is using the same zoom features as found on my 50s. I shoot raw plus large jpeg so that I could have a really clear image for checking in the field. The initial zoom for the jpeg file is way beyond 100% and I found that 8 clicks of the wheel for minus zooming brought the image to a perfect 100% and extremely clear ln both the LCD and the EVF. I would expect this EVF to be even better when using the power option for higher resolution.

I knew there was a reason I left the GFX on raw plus jpg. It’s for the image review issue. Never figured out why Fuji could not either understand what was going on or understand why a precise 100 percent review was needed.
Victor’s technique is the same process I use for review. 2x tap to get the view at like 150 percent then I used the pinch the screen like an iPhone to shrink the view back down. I really had hoped the GFX100 has a different design for this. I mainly used AF when using the EVF since on the GFX it worked quite well except very low light situations. Manual focus with peaking was another problem as Fuji’s peaking is unlike a Sony camera or Nikon’s. Hard for me to dial in tack focus. But the AF when it got a hit was 100% reliable.
Hope to hear more feedback from folks with the 100 on these issues.

Thanks a lot.
I was hoping a one click jump to 100%, but I guess that’s not possible.

Does anyone know of a good L-bracket for the GFX-100?
-
My first slight concern is that the camera has a rattling sound on slight impact. I'm assuming this is the IBIS system but has anyone else noticed this?

I called Fuji and the slight rattling that I hear is from the IBIS and is normal. Considering all the bouncing around that FedEX gave it I was a little concerned but the camera is operating properly. IBIS is a dream for a camera this large....... works extremely well - way beyond my expectations. All zoom views (taking and playback) are better than the 50s.
Victor
-
That’s good news indeed.
Paul C

Live view is certainly so much better. I really like the camera. I am really looking forward to test all lenses again and get ready for some serious work. One thing or rally don’t get us who designed that vertical grip..... it’s not as bad as I feared, however, compared to a 1D it feels like crap. It works for shooting, but I wouldn’t want to carry the camera like that.
-
RRS claims their new L bracket will help give the vertical add a bit to the mass of the grip and give you a bit more to hold.

I believe that my Fuji X-H1 rattles as well (the only other Fuji camera with IBIS). Fuji does not seem to lock the IBIS as Nikon does when the camera is off.

So far with all lenses that I own that can be shot with the Fuji 100 nothing comes into critical focus. I have done all of my testing with the camera on a tripod with both IBIS on and off. I've shot with technical lenses and the Fuji lenses but it's just crap. 100% view shows all images to be soft..... so soft that nothing could ever sharpen them to my expectations. Same images shot with my 3100 and same tech lenses used on both cameras is night and day. Mine is going back.......

What raw converter are you using ? Adobe has not yet finalized their support for GFX100.

Victor, that sucks. Sorry to hear it. Hope they can get a replacement to you soon.
What happens when you use the camera AF? Does it lock and give a sharp image on the LCD or EVF.
Only thing I can think of is the firmware for the lenses. But I am sure you did that. And it would not explain the manual tech glass. Wonder what happens when you turn off IBIS.

To get the level, go to Set Up menu group, then over to Screen Set Up, then go to the second screen of options, select Disp. Custom Settings. There are a bunch of options. Select Electronic Level. It shows one dimension. It does not show forward pitch. In other words, you can be level horizontally, but looking upward or downward.
-
Those are all really good questions, Paul. AF makes no difference. Sure, there is a sharp image in the finder as I'm used to but that sure isn't the resulting image. I don't think firmware for lenses makes any difference. I used my tech lenses with the same results. IBIS off or on makes no difference. Something is really awry.
Victor

Can you post a sample? Especially compared to the IQ3100.

Are you experienced with, and know how to achieve critical focus with the GFX 50x? If not, try this before you return your camera.

What happens when you use AF and a native lens?

to jump to 100% view you can set "focus check" on. any time you manually adjust the focus it will jump to 100% until you let go. The screen/evf has to be in one of the full screen modes (not the one with a frame and secondary focus window) for this to happen.

I need to modify this. On further examination of the instruction manual, there is a three-dimensional level. It is discussed on pages 223, 256, and 259. I was able to use it once I assigned the level to a function button. It is assigned by default to the touch screen menu.

Hi,
I checked out the preliminary DPReview images and I found the GFX performed pretty much like GFX 50R, that was tested with the same lens, at least regarding MTF.
After that Rishi Sanyal, who is science editor at DPR, confirmed there was an issue with focus on the test image, although they made a lot of effort to improve the test methodology.
They are going to reshoot, but not before final firmware is available.
I am a bit concerned about focus by wire, especially on lenses using voice coil as means of focusing. Early samples of the GFX 50S had issues with unforced focus shifts, I am pretty sure that has been worked out.
Hopefully, DPR gets an optimal test image on next try, that would be a good reference point.
Best regards
Erik

I am using the Arca Swiss Universal L Bracket on my GFX100. The L Section removes completely for easy access to the long battery tray.& B & H is currently is running a special for around $225.

Team,
Quick one, how is it possible to change the live view/EVF magnification zoom level when shooting MF?
Thank you.

Is this useful?
-
Thanks Jim.
Yes. In fact I now understand that the level of zooming can apparently not be adjusted when you using the left/right display split btwn zoomed view and full view but only when in full screen zoom vuew.
Is your understanding the same as mine?
Also, I guess there is no possibility to always jump directly to a preferred level of zooming? It’s very inefficient for landscape work to have to always zoom manually.
If correct this would be a really pity because that view is super efficient.
Thank you.

I don't have my GFX 100 yet, so I can't speak from personal experience at this point. I never found the thumbwheel magnification on the GFX 50S to be a problem, but this is different. We now have three different Fuji 33x44 mm cameras with three different user interfaces. Yikes!

The GF lenses as delivered do not have the 1.10 firmware update installed. The 1.10 Firmware update has the Phase Detection Autofocus code. Without this update the lenses do no focus properly. Its easy to download and install. While your at it make sure your camera firmware is up to date. Here is the link for the GF lenses Firmware. As you can see in the description column the 1.10 is updating each lens for Phase Detection Auto Focus.....Good Luck!

Just to add to what's been said. you can put all of the FW updates for all of your lenses on a single card. Then just put the card in the camera and attach each lens and start-up the FW update. The system knows which one to use for the lens that's attached. There is no need to put the FW on the card one lens at a time.

Thanks for that. I didn't have the nerve to try it.

Jim,
We all appreciate all the testing you have done and results provided! Have you done any Continuous Auto Focus testing/Low or High Speed Burst as it relates to optimal settings for tracking a moving subject?
Such as:
Which AF Mode works best; Zone or Wide Tracking
Which AF-C Custom Settings Work Best:Tracking Sensitivity, Speed Tracking, Zone Area Switching or custom 1-6 settings?
Is it better to use "Shutter button focus and release" or "Back Button Focus and Shutter release" only?
I have been playing around with all these modes but, have yet to find optimal settings with a consistent hit rate of critical focus.
Any Thoughts?

I don't have any way if doing quantitative, repeatable testing of AF dynamics. So I'm just throwing darts in the dark like everybody else.
Sorry.
