  1. 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.
  2. EOS R rolling shutter test from Weibo: 30.45ms in 4K 30P
  3. 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!
  4. 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+).
  5. 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.
  6. 120P on X-T3 seems to be pixel-binned instead of line-skipped, it's a bit soft but aliasing artifact free.
  7. The source on Weibo was suggesting a supersampling algorithm similar to how C300 derives 2K 444 from 4K sensor - 4K 444 from 8K readout.
  8. 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.
  9. Thanks! Fuji website says 16ms rolling shutter for 4K 60P, cinema5D says 9ms for 4K 25P. Do these numbers align with your own observation?
  10. Some love for the almost forgotten A7S III: https://www.cinema5d.com/where-is-the-sony-a7s-iii-video-interview/ Leaks from Weibo: Exmor RS sensor 4K 120P with crop 8bit/10bit X-OCN with grip
  11. 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.
  12. 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.
  13. 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.
  14. Did you try face detection & tracking?
  15. The newer f/2 primes and f/2.8 zooms are quad-linear motor so AF-C performance is much improved. On X-T3 older gen lenses got a bump in performance but still cannot compete with the newer ones.
  16. Regarding noise, it depends on how you look at the pixel count. On a 1:1 level, the 100MP sensor has identical noise performance as X-T3, it's the same 3.76um photosite architecture, the 100MP one is like four X-T3 sensor stitched together. If you normalise the images to standard 8MP (DxO "print" test method), the 100MP will have at least 3EV more DR in theory.
  17. It's about FOV and perspective distortion. A 50mm lens on MF will have 50mm perspective distortion but equivalent of 35mm FOV, making things look "grand". Of course it's easier to achieve shallow DOF with MF, but it's not the only thing.
  18. DR400 in Eterna would definitely make a difference, since they both share the same base ISO of 640. I'd think of it as Eterna LUT applied internally.
  19. What do you mean? Some of the shots have harsh highlight clipping, I think if you used DR400 with Eterna you would have better highlight roll-off. On X-T2 the DR mode isn't available in video mode.
  20. Thanks for the test, did you use DR400 with Eterna? You get about 12 stops of DR.
  21. Again from the senior semicon enginner on Weibo: X-T3 uses a Sony sensor, same 3.76um photosite architecture seen on medium format sensor IMX411/IMX461, with BSI, copper interconnect and 16bit ADC. Think of it as a crop from the medium format sensors. According to this engineer, Samsung does have a APS-C sensor but it's only recently taped out, 50MP ISOCELL+HD which is equivalent to Sony's Exmor RS, but without the DRAM.
  22. Looks like 100P/120P on X-T3 went from line-skipping (X-T2/X-H1) to pixel-binning, sharp horizonal lines like the fence are clean unlike X-Trans III. Reasonable amount of detail but definitely not supersampled from the entire 1.29x sensor area.
  23. Yep, TowerJazz FF global shutter, according to a senior semicon engineer:
