  1. Camera2 API is for Android. iOS camera API does not yet allow sharpness/noise reduction control in either photo or video mode.
  2. Can the background colour be a dark neutral gray instead of navy blue? It's still blue light and may be too much of a visual stimuli, defeating the purpose of a dark theme which is often used at night. Also can the forum width be a bit wider? I find 80% still leaves too much blank space.
  3. Based on an industrial sensor https://www.gpixel.com/products/area-scan-en/gmax3265-3-2-μm-65-mp-global-shutter-image-sensor/ Image quality is shit.
  4. Sony Semicon imposes strict licensing restrictions, one of these restrictions is that certain sensors can only be put in specific products (eg. mobile phone only). This is why drone cameras from Autel/DJI have only recently started using the more than 3 years old IMX586 sensor.
  5. 23.6MP sensor (IMX677), 5K 30P Video (5120 x 2880), 20MP photos, 1.4in front screen for preview/status, 2.27in main screen, 479 Euro.
  6. Leaked image of Canon engineer working on R5 firmware update:
  7. The guy who did the teardown uploaded new FLIR images showing the temperature after the "overheating" shutdown. Highest spot was 64C. http://c.tieba.baidu.com/p/6848700307?pn=5
  8. Yeah, a simple qualifier and a small amount of blur got rid of the moire: It must have happened by coincidence - the texture of the t-shirt and the sharpness/focusing of the lens produced just the right amount of high frequency detail that the sensor could not resolve. Maybe next time you can ask the subject to be shirtless, moire-free guaranteed and you'd get more views
  9. It's not 5%, it's been updated to 0.2%. I downloaded it, and it's just boring website assets like product promo videos, marketing copy, layout designs and stuff, from years ago.
  10. It's not done "in-sensor". The two readout paths are both derived from 14bit ADCs, they are processed and merged by a 16bit ISP. Roll-off as well as other ARRI colour science processing happen when doing this 28bit > 16bit conversion.
  11. There's absolutely highlight roll-off on a digital sensor with dual/multiple gain readout. The roll-off is applied when merging the high gain and low gain readout path, which is how ARRI does it.
  12. It has good cinematography, but it doesn't show a lot of DR, especially in highlights (F5/F55 don't have much highlight DR either, around 6EV). Pay close attention to the way the sun and the surrounding clouds were blown out,
  13. Graded and matched to Alexa using the above footage, with CineMatch plugin:
  14. Off topic but relevant here, R5 rolling shutter official test results have been published: https://www.slashcam.de/artikel/Kurztest/Die-Rolling-Shutter-Werte-der-Canon-EOS-R5.html 8K30/4K HQ: 16ms (indicating a 8K 60fps readout) 4K normal 24-60fps: 10ms 4K 120fps: 8ms
  15. He shot 15min 8K All-I (no overheating warning showed up). Turned off for 10min, then kept going non-stop till the 512GB card was full. But, when he shot 20min 8K until the camera auto shut off, then cooled the camera to ice cold with an AC, he could only shoot additional 5min of 8K. FLIR camera showed the CMOS at 44C and CPU/main board at 69C when the camera auto shut off.
  16. This thread details the teardown process, modifications made and some important findings: http://c.tieba.baidu.com/p/6848700307?pn=1 He replaced the two thermal pads that did not fully cover the CPU with a dollop of thermal paste and noticed significantly better and more even heat dissipation. Most important finding: despite the temperature drop and improved heat dissipation, 8K/4K HQ still cut off at 20min mark, suggesting a firmware limit is also in place.
  17. A7S III colour science is certainly improved and offers a much better starting point for colour grading. Here are some samples matched to ARRI Alexa with minor adjustments, using "CineMatch" sensor matching algorithm, the A7S III sensor profile is still at beta stage.
  18. This really demonstrates how much NR is going on internally:
  19. Mostly a marketing tool so people perceive it as on par with those CineAlta cameras.
  20. You can download a sample, shot at 0EV and see for yourself.
  21. 4K 24-60P and 4K 120P have almost the same level of sharpness and detail. And 1080P is not supersampled, but pixel-binned from 24-60P and line-skipped from 100-240P.
  22. Someone dissembled R5 and found barely any heatsink and shockingly there was no TIM (thermal paste).
