Crop in 4K60 is 1.18x, the 1.25x crop is the sports finder mode for 30fps stills shooting. Also just FYI, the 120p mode is 1.28x crop. Quite different. X-T2 has no crop in all 1080p mode including 120p. 1.18x crop in all 4K framerates. X-T3 has no crop in 1080p up to 60fps, then 1.28x crop in 100/120p. (very likely to be supersampled from the crop area, the images are aliasing free). No crop in 4K up to 30fps, then 1.18x in 50/60p.

F55 is the only global shutter cinema camera.

From Weibo:

As discussed before, HEVC smoothing filters SAO and SIS contributed to that waxiness.

Only the cover is removable. There are third party services that replace the stock lens assembly with a higher quality, near-zero distortion one.

It IS remarkably good, and I hope it can be remarkably better!

TBH the exFAT file larger than 4GB should be available at launch. I hope AF especially AF-C/Face detection are being worked on as well.

Ha I'm not that daft prick, are you? https://www.fujirumors.com/fujifilm-x-t3-new-firmware-will-add-exfat-file-system-support-eliminating-4gb-file-size-limit/ The Weibo lady is a well respected figure in the Japanese semiconductor industry.

SAO and SIS are essentially smoothing filters and are bitrate independent. UHD BD authoring tools have these turned off. http://iphome.hhi.de/wiegand/assets/pdfs/2012_12_IEEE-HEVC-Performance.pdf

Yes, these two filters are designed to preserve overall image quality at low bitrate, at 200/400Mbps bitrate Fuji implemented, they really should disable those filters to allow more fine detail to come through.

X-T3 10bit encoding anaylsis from Weibo: https://www.weibo.com/KazuoHiraiSONY?is_hot=1#1538181717102 X-T3 10bit HEVC encoder has SAO (Sample Adaptive Offset) and SIS (Strong Intra Smoothing) filters enabled, which unfortunately reduces high frequency detail.

EOS R rolling shutter test from Weibo: 30.45ms in 4K 30P

Fujirumor did an interview with Fujifilm manager and he said GFX100MP will use full sensor readout for 4K, no line-skipping or pixel binning. That's a whopping 11664 x 6561 readout from the 4:3 sensor! With over 3x supersampling the images would be clean af!

Fuji Kaizen update news: 1. X-H1 to receive firmware update to offer dual IS (IBIS + lens OIS), which adds 1.5-2 stops of additional stablisation. 2. X-T3 (and very likely X-H1/X-T2) to receive firmware update to enable file size larger than 4GB when using SD cards formatted as exFAT (64GB+).

Great pictures! You're right about #1, it's a completely new generation of sensor, 3.76um photosite architecture that's also used in the 100MP sensor in GFX100.

120P on X-T3 seems to be pixel-binned instead of line-skipped, it's a bit soft but aliasing artifact free.

The source on Weibo was suggesting a supersampling algorithm similar to how C300 derives 2K 444 from 4K sensor - 4K 444 from 8K readout.

Yeah I understand, just curious about the higher rolling shutter in 50/60P compared to 25P, 16ms/9ms almost 2x. Did you notice that? I though higher framerate usually result in lower rolling shutter. Whici DR mode did you use for the comprison? DR mode is now available in video mode like X-H1, Fuji quotes 12 stops DR with DR400 and Eterna.

Thanks! Fuji website says 16ms rolling shutter for 4K 60P, cinema5D says 9ms for 4K 25P. Do these numbers align with your own observation?

Some love for the almost forgotten A7S III: https://***URL not allowed***/where-is-the-sony-a7s-iii-video-interview/ Leaks from Weibo: Exmor RS sensor 4K 120P with crop 8bit/10bit X-OCN with grip

Latest leak from Weibo: S1/S1R use Sony global shutter sensors. S1R has 150MP pixel shift mode for photos. 4K60p supersampled from 8192x4320 sensor area.

https://www.atomos.com/drives You don't have to use the Angelbird mini SSD, full size drives work too but they will protrude to the left side a bit.

Thanks! I'd love to see a low light ISO test with noise reduction all the way down to -4. Judging from the JPEG performance, X-T3 could potentially retain excellent detail up to 6400.
