  1. Ha, I've explained many times, current commercial CMOS sensors behave linearly, and linear 12bit = 12EV = 12 stops of DR. Yes you can store unlimited DR in 8bit, that's called logarithmic encoding.
  2. 15 stops DR? With current Sony sensors, 12bit ADC readout maxes out at 12 stops of DR. With the Dual Gain HDR, it's a Digital Overlap Drive with double rolling shutter and half the framerates. Not very practical for cinematic work. But Fujifilm has already kind of implemented this DOL drive in X-T3/30 and GFX100, with the shutter speed slower than frame rate feature.
  3. If you visit this link: https://www.sony.com/electronics/interchangeable-lens-cameras/ilce-7sm2 and change the last bit of the URL "ilce-7sm2" to "ilce-7sm3", it redirects to a specific page. But it you change it to anything else, including "ilce-7sm4", it just displays a generic 404 page. Suggesting that "ilce-7sm3" URL is already reserved.
  4. New firmware announcement around IBC as well ?
  5. Expect a relevant announcement at IBC later this month. Readout speed is believed to be ultra fast at < 12ms.
  6. 4K pixel to pixel has a bit more noise than supersampled 4K from 6K. A bit softer as well with some moire/aliasing. S1H is even more soft but with reduced moire/aliasing due to the addition of an OLPF.
  7. 4K pixel to pixel/S35 goes up to 60P and has a bit less rolling shutter (16ms vs 21ms).
  8. On S1 and S1H, 4K pixel to pixel readout is the same as S35 mode, it's a 1.5x crop.
  9. There are quite a few large format anamorphic lenses for Alexa 65 that fit GFX. It’s a new cam because it’s a GFX with X-Trans IV CFA.
  10. Would be great to implement a 3 x 3 colour aware binning on X-T3 for 2080 x 1386 RGB, but I think it’s unlikely because colour aware ADC is introduced in 3.76um gen 2 sensors (IMX461XTK)
  11. It’s an anamorphic mode. And due to a 3x3 colour aware binning, it’s completely free of moire/aliasing, also with drastically increased sensitivity. Kinda similar to those 48mp > 12mp smartphone sensors but much much more advanced.
  12. As you may be aware, Fujifilm has registered three new cameras: FF190001 FF190002 – X-Pro3 FF190003 One of them is a 44 x 33 large format video centric camera with 4K x 3K RGB output.
  13. Sony Professional Video division negotiated with Sony Alpha to reserve IMX571 for its future pro camcorder products.
  14. Yes the upcoming new firmware addresses the AF issue.
  15. There will be a new firmware announcement around the same time as a new product announcement.
  16. a6100: IMX210 a6600: IMX284 Arriving in a few hours.
  17. 4K video on M6 Mark II is derived from pixel-binned 3.5K Bayer output. Disappointing.
  18. It's still the IMX410, full pixel readout can only go up to 40fps @12bit
  19. Rolling shutter performance: 7680x4320/24.7ms 9472x3996/22.2ms 6144x3456/19.9ms(Low Noise)/13.5ms 9472x1332/8.1ms 7680x1080/6.7ms
  20. It's been pointed out multiple times in this thread, that this speedbooster sits completely within the mount as a set of pure optical elements, it does not alter the EF mount in any way therefore does not change the focal flange distance.
