Do we know anything about weather sealing? 🙂
Same as a7RII
Basically nothing then XD The A( is reported as being a bit better, which is why I wondered 🙂
A7R III offers better image quality for both stills and video.
what about electronic shutter distortion? Does it have any since it’s the same sensor as a7rII or is it no distortion like on a9?
Eye AF with A-Mount lenses… That’s great for me! This camera sound ultra good!
When shooting in 1080p 120 FPS, is there a crop factor like the A7SII does (x2.2) in 120 FPS? Fingers crossed for no… Thank you!
Full width of sensor.
When bracketing (including if use self-timer), does bit depth decrease on the A7r3 and if so, by how much? On the a7r2 reportedly this drops bit-depth from 14 down to 12. To maintain the full 14 bit-depth in th a7r2 you have to actuate the shutter for each individual image in the bracketing.
Any Continuous Shooting Mode drops bit-depth from 14-bit to 12-bit when RAW Compressed is selected.
Continuous Uncompressed or Lossless is 14-bit. Single Shot Mode is 14-bit.
Large improvement in sharpness? You mean in JPEGs, right? How can there be a large improvement in sharpness shooting raw if the resolution is the same as before? Do you have some side-by-side examples you could share?
Nope. RAW too. New Image Processor is a hardware upgrade that reduces noise and improves dynamic range a full stop.
Hi – am semi-amateur filmaker. If you had to purchase either A7Sii or A7Riii for videos and live streaming, which would you choose?
Hi Charles, both are great cameras, but the new features on a7R III would sway me in that direction. https://briansmith.com/top-15-reasons-upgrade-sony-a7r-iii/
