Sadly Fujifilm continues to ingore our request for an Instax Wide Printer, which is incomprehensible for me. It can’t cost them massive R&D to develop one.
The Fujifilm GFX100 is about to ship, and what we have for you is one last glorious Fujifilm GFX100 roundup, before it starts falling into hands of mere mortals (with pockets a bit bigger than mere mortals ;) ).
The Slanted Lens tested the Fujifilm GFX100. Problem? They didn’t use the latest firmware that adds support for phase detection AF on GF lenses, and Lightroom still officially marks the GFX100 as preliminary supported. Sadly this makes every review so far incomplete.
With that said, here is what they think about the GFX100 (video below).
details are amazing
in medium format at f/2 you have so just very little DOF
dynamic range test
at -5 EV he is still able to recover the hightlights with no problem
he thinks it could have been underexposed for at least two more stops, and he’d be able to recover that
at +1EV he is able to hold the highlights, with just a little bit pink color shift
at +2EV the highlights are gone, with yellow color shift
at +3EV the details are gone, skin tones are yellow
at +4EV it’s basically blown out. No way to recover that image
if you work in very contrasty situations, this camera will work extremely well, because of amazing shadow recovery
pretty amazing dynamic range
ISO test
ISO 100 very clean
ISO 200 there is a little bit of grain
ISO 400 also a little bit of grain
ISO 800 grain builds up more
ISO 3200 grain starts to become very pronounced
ISO 6400 major grain. He thinks it’s unusable for stills
ISO 12,800 becomes pixelized
ISO 256,000 grain is extremely strong
He’d not go over ISO 400 for clean images in stills and in general up to 1600. For video up to 3200
even at higher ISO, the colors remain consistent, no shift
Autofocus
in stills he is not as impressed as he hoped for [I noticed when the subject was far away, the tracking was not so reliable, but more close, super sharp. I personally wonder about his AF settings. Also, pre-production, you know :)]
in video holds the focus well on the subject, and AF is as good as anything else on the market
IBIS
Impressive. Might be a great camera to put on a drone
The vast majority of people, who are going to get a Fujifilm GFX100, will get it for its photographic virtues.
However, the Fuji GFX100 is also the first medium format mirrorless camera that can fight an honorable battle with full frame and APS-C in the video department.
4K@30p, 4:2:0, 10 bit internal… not bad at all!
This is why I decided to highlight this review by Muse Storytelling, which focuses on the Fujifilm GFX100 for filmmakers. He says:
the whole demo video you see has been shot handheld with Fujifilm GFX100
10 bit gives you lots more colors over 8 bit and allows for more post processing
understanding Fujifilm film simulation allows you to create amazing images in camera
Velvia is great for scenes that look bright, happy and energetic
Classic Chrome more subtle and subdude look is great for interviews and moments with a serious or sad tone
external recorder for 4:2:2 10 bit image allows for simultaneous F-Log and film simulation recording
using film simulation you got to get it right in camera, less flexibility in post compared to F-Log
when using the LCD screen in bright daylight and shooting F-Log, it becomes a bit difficult to evaluate exposure and focus on the LCD screen, but it’s totally fine if you use film simulation
very customizable
changing settings takes a bit longer than on dedicated film cameras like the RED camera they use, but you can set custom buttons to speed up your workflow
they say in most cases, for film you better use manual focus. But the AF system on Fujifilm GFX100 is great, and for interviews with people moving back and forth, the eye AF worked better than they could have done by manually focussing
sweet spot for exposure seems to be 1 stop over: gets all the shadows properly exposed and away from the toe of the curve
when using F-log or Eterna, the GFX100 holds highlights very well
he is impressed with image quality, handling and features for such a compact camera with such a massive sensor
they will use the GFX100 a lot more in future for their video work
Thomas Fitzgerald tested it and has written about it on his blog here. His conclusion:
The changes are very, very subtle to the naked eye.
The update fixes some issues that can occur when there is very fine repetitive detail such as tree branches, leaves, foliage and things like that.
It’s as if they have improved the anti-aliasing algorithms ever so slightly.
It’s something most people probably won’t notice, and they didn’t have to do this, but it pretty much eliminates most rendering artefacts from X-Trans files.
For years, mirrorless cameras lagged behing DSLRs in terms of autofocus speed.
In order to catch up, companies started to incorporate phase detection pixels on their sensors, and modern cameras have phase detection pixels spread all over the sensors, very much to the delight of photographers, who enjoy fast autofoucs, eye autofocus all over the frame and reliable subject tracking.
But no technology is perfect, and so also phase detection has its downside.
When pushed to the extreme (meaning extreme shadow recovery for example), sensors with phase detection pixels can show some banding.
This has been documented with Nikon, Sony and so forth, and of course Fujifilm is no exception. They all use the same Sony sensor at the end of the day :).
It looks like also the Fujifilm GFX100 is (unsurprisingly) showing the same banding issue, when its RAW files are pushed to the extreme.
In fact, the Fujifilm GFX100 sensor has
a total of 3.78 million phase detection pixels
7,776 PDAF pixels every 18 lines
The more phase detection pixels a sensor has, the more you can use phase detection also in lower light.
Bill Claff from Photons to Photos has published a Fujifilm GFX100 sensor heatmap (via dpreview), showing a short black line every 18 rows (see image above).
Should we panic?
I guess not. Or we could just throw any modern mirrorless camera into the garbage that uses phase detection pixels (unless it’s X-Trans ;) ).
It’s, as always, a tradeoff.
Do you want faster autofocus? Or do you want RAW files that even when pushed to its limits and beyond don’t show banding?
The Solution
First off: Fujifilm is fine tuning the firmware for the Fujifilm GFX100, and of course they are aware of banding. They are working to optimize sensor readout and the final firmware will show, how much banding the camera will really have.
But in any case, there is partially a solution to that, even without optimized and final firmware.
As I told you already months ago, Fujifilm is working to bring pixel shift multishot into the Fujifilm GFX100.
The original goal was to have it ready for GFX100 launch, but it needs a bit more time of development.
But pixel shift mulitshot will come, and as we have seen from other phase detection mirrorless cameras offering this feature, pixel shift reduces or even eliminates banding completely.
So, as long as you are shooting static subjects on a tripod and use pixel shift multishot, you won’t have any issues with banding.
