  1. Canon has a FF 10.1MP Global Shutter sensor in the works, could be used in a video-centric mirrorless model.
  2. They are OEM for Ikan, very good quality and customer service.
  3. I personally find that floaty ultra smooth movement kind of offputting. GoPro Hero 7 Black essentially has a "SteadXP" like device built-in.
  4. Would wireless follow focus work well on fly-by-wire lenses such as Fujinon XF ones?
  5. DR400/F-log mode has plenty of fine grain with NR -4, even at base ISO, no need to add in post
  6. The 4K interframe NR is a handy feature for special occasions, when enabled the images are clean and completely usable up to ISO12800, with a small amount of detail loss.
  7. At 5.5um its native DR is only 60dB, while A7R III offers 80dB at 4um... I can't imagine the further DR penalty if they increase the pixel density.
  8. Looks like a CMOSIS CMV series sensor: 5.5um pixel size, global shutter and 12bit ADC match several CMOSIS SKUs And the funny thing is the 60-90dB dynamic range swing is exactly the trick from CMOSIS, native DR is 60dB, extended DR is 90dB with Full Well Capacity Temporal Limiting. I doubt CMOSIS would custom produce a FF version for Pixii, so the most likely SKU Pixii is going to use is CMV12000, an APS-C sized sensor that matches all announced specs.
  9. X-T3 has many power management optimisations. One of the key aspect is the IMX571 sensor has significantly reduced power consumption, compared to the 24MP IMX271.
  10. Scientific tests from Fujifilm website:
  11. Really? I thought all lenses, including medium format and 65MM/IMAX lenses are marked with 35mm focal length?
  12. What do you mean no need to multiply by 1.5? I thought all lenses are marked by 35mm focal length. So 18-55 would have FF equivalent FOV of 28-85?
  13. The 4GB file splitting will be fixed in a firmware update in November.
  14. Well X-T3 can do 200Mbps for 1080p at all framerates.
  15. How do you monitor in 2.39:1 or other aspect ratios? There's no framing guidelines in DJI Go app.
  16. It's a teardown, the Sony SKU is clearly marked on the sensor assembly ? Just putting this out there - Nikon does not have the capacity to design image sensors from scratch, like many big companies such as Apple, Fuji, Phase One, Hasselblad, they buy off-the-shelf products from Sony Semicon, the key difference here is Nikon secured exclusive supply from Sony, the IMX309 in D850 is an example, and possibly Z7 as well.
  17. https://nikonrumors.com/2018/06/15/new-reports-indicate-that-the-nikon-d850-sensor-imx309aqj-is-made-by-sony.aspx/
  18. Fuji designs the CFA on top of the Sony sensor. While Nikon just use the Sony sensors as is.
  19. Atomos has a normal priced one too: http://amzn.eu/d/dPjvpYa
  20. Alexa's rolling shutter is about 4.5ms, the minimum required to reach 200fps full readout. How would a camera correct rolling shutter when a train flies through the frame while the camera is static?
  21. Yeah I wonder how the 1080p is derived from 6K, the image is sharp but has heavy aliasing. Looks like a combo of pixelbinning and lineskipping.
  22. Come on Andrew, the NDA lift was yesterday. Fuji staff has confirmed X-T3 uses IMX571 on Weibo. Sony sold the sensor to Fuji and made the CFA on top of the sensor to Fuji's specification. The difference in readout speed is simply caused by bitdepth. The quoted 19fps resolution is at full 14bit. The sensor can also operate at 12bit and 10bit.
  23. All the 1.4 primes work ok and actually improved with X-T3. But they're highly unpredictable. You could wait for the new 16-80 f/4 zoom with OIS.
  24. All of the new f/2 primes and f/2.8 zooms.
