A leaked data sheet for a new Sony IMX435 sensor, one of the two 8K Sony sensors mentioned a few days ago has come out. It appears to be the 36-megapixel one, potentially offering 8K video at 60fps and a strange super ultra wide 4K (3840×1080) at up to 480 frames per second. It’s suspected that this might be the sensor that will reside in the much anticipated Sony A7SIII.
The full leaked data sheet, which comes via the EOSHD forums, is below, but it’s a little odd. It shows 8K (well, 7680 x 4320) capable of shooting up to 60fps at 12-bit depth, and that strange 32:9 aspect ratio 3840 x 1080 resolution getting a pretty crazy 480fps at 10-bit depth. So, it’s 4K UHD width, but not height.
4K UHD at 3840×2160 resolution could theoretically sit at around 240fps. Whether or not it’ll be 10 or 12-bit is unclear, but I think it’s more likely to to be 10-bit if this speed actually offered. I can’t see Sony jumping into CinemaDNG territory, or bringing out their own raw video format to their mirrorless cameras when they actually have a full line of dedicated video cameras.
As this is a leak, it’s to be treated like any other rumour for now until Sony announces something officially. Although Andy at EOSHD does say the source of the leak has proven correct in the past. But even if it is legit, I would imagine this sheet is still subject to change as it doesn’t list any real 4K UHD (3840×2160) frame rates yet.
It has been suggested that Sony are open to licensing these sensors out, too. So, we may see them in upcoming cameras from the other big names, too, in the near future.

Sounds more like a new fs7 . The specs wont be in a <5000€ or even <10.000€ camera
8k is overkill for me but fuck yeah 480fps for 4K
Sounds like overheating for me.
Yea, but can it make a decent cup of coffee. Kidding, I still love my A7RII and will waiting for the A7rIII update before I move on.
Nothing to do with the sensor size its the processor that has to be upgraded to handle the bandwidth.
Ummn can we at least see a new camera sometime in this next year?
My fs5 is getting elderly and I’m getting ready to jump ship from Sony
and look elsewhere for a new workhorse…
this would be really useless…. and I don’t think that sony will change their beloved SD card format for sth faster to handle 8k.
People want 10bit, 4k, AF-C, 60fps, 120fps and log….
if this is happening at the sort of prices of other A7 cameras, it’ll absolutely obliterate the pro video market….
8K 60fps is impossible with any SD card. Must be fastest SSD to handle this and for A7 body – there is nowhere to fit it. Maybe NVMe type of SSD. Data rate should be over 1 gigabit per second.
Good call. Your on to something here.
It would only need about 12.5MB/s write speed for compressed video. Youtube is currently using 21.2 Mbps (2.65MB/s) for their 8K video. https://www.tutorialguidacomefare.com/test-video-quality-720p-1080p-1440p-2160p-max-bitrate-which-compresses-youtube/ For raw, it would take 2GB/s which only a nvme could handle as you stated.
1 gigabit per second = 125MB/s
There’s sd cards recording at 250+MB/s
