Fujifilm GFX 100 w/ phase-detect AF & 4K video

Quote:
The GFX 100 features a medium-format (44 x 33mm) BSI-CMOS sensor with 102 million effective pixels. The camera is powered by a quad-core X-Processor 4 and offers a native ISO range of 100-12,800 (which expands to 50-102,400) and support for 16-bit Raw files. In-body 5-axis image stabilization reduces shake by up to 5.5 stops according to Fujifilm, and the entire sensor is mounted on springs to reduce shutter shock.


The GFX 100 has a dual-hinged, 3.2" touchscreen LCD with 2.36 million dots that can tilt in both landscape and portrait orientations, just like on the GFX 50S. The camera comes bundled with a removable, tilting OLED EVF that has a whopping 5.76M dots. There are also a pair of OLED displays - one on the top, another below the LCD - that display various camera settings, battery life and shots remaining.


Fujifilm has put a hybrid autofocus system on the GFX 100, with 3.76 million phase-detect pixels spread across nearly 100% of the frame. The company claims that AF speeds are 210% faster than on the contrast-detect-only GFX 50R, and our early experience suggests that autofocus is indeed vastly improved.





The last of the major features on the GFX 100 is its video capabilities. It can capture DCI and UHD 4K video at bit rates up to 400Mbps, with your choice of H.265 or H.264 codecs. It supports Fujifilm's Eterna Film Simulation mode and can output 10-bit 4:2:2 F-Log video to an external recorder.

And yet for this price, it still won’t do 4K60p.

That is one ugly camera.

Apparently they hired former Volvo designers.

Compared to the competition, it looks pretty nice to me: http://j.mp/2X9RwZL

It looks like I will continue to use my current gear (GH5, a6300, a7r, NX1, P1000 etc.) for another year .

Twin SD card slots
Twin SD card slots operate as you'd expect, and can be set up for overflow storage, backup or separate stills / video storage. The GFX 100 is UHS-II compatible, and with a fast card installed, the camera is remarkably quick in operation.
Whereas it's not uncommon for other medium-format digital cameras to start to moan and wheeze after a few high-resolution Raw exposures, the GFX 100 appears to have power to spare from its quad-core X-Processor 4 engine. To photographers, the benefits of this speediness should go without saying. The downside is that with 100MP to play with, and a processor that can keep up with that many pixels, it's all too easy to 'overshoot' and run out of card space.
That being said, our shooting so far has been in 14-bit Raw mode. It's unlikely that the GFX 100 will be quite so light on its feet when capturing extended 16-bit Raw sequences.

Can't see anywhere in the specs that says it has a full sensor readout for video. A cropped window or pixel binning will negate much of the benefits of greater pixel data and larger photosites and that will have to come down from a sensor whose aspect is clearly not designed for video capture (4:3 not 16:9). This looks to be mainly for still photography otherwise too much overall hardware for too little video finesse it seems.

Yup. I took both the Osmo Pocket and A7iii to the zoo today. In the strong contrast created by the bright sun & deep shade, the OP just fell apart. The tiny sensor just couldn’t handle the dynamics of today’s stark outdoor lighting. The Sony’s much greater DR were far superior for this. Yes, although not surprising, it was still interesting to see such a difference.

Aside from the video quality, the usability between the two was just as different. The OP was very tough to see with its tiny screen. The Sony, with its OLED EVF, was a joy to use.

Of course the stabilization sets the OP apart and the Sony can’t touch it in this respect, but I have to say in the end, I’m finding I don’t enjoy using these tiny cameras. Yes, there’s a time & place for them, but I’m just not finding the fun factor. I’d rather schlep the big Sony and enjoy the shooting experience.

new Panasonic L-mount Cine Lumix camera May 31st !

This looks like it will be a fraction of the price of the GFX 100 and with much better video specs .

But I will wait for the GH6 in 2020 since I already have the lenses.

Thanks for posting that. The wave stills were fantastic but I was not impressed by the dynamic range on the video. Do you know what camera(s) they used for the cinematography?
