All BionzXR cameras are capped at 8K30FPS, 6K60FPS or 4K120FPS readout/sample rate for video in 12bit mode, no matter how fast the sensor is, I guess that's the upper limit of the processor's video encoder capability. it translates to roughly 1billion pixels per second.How is the BionzXR speed measured? Are there benchmarks out there? I have been wondering about the speed and if it has increased from the A! to the A1 II and if so how much? Any thoughts on how to quantify this? Thanks!The BionzXR is quite inferior compared with its competitors. The AI part is more like a cheap patch to the issue for autofocus but that works really well.I think no in-body focus stacking is the most surprising part taking into account the overwhelming computational power of the thing and now moreover supercharged by AI... Surprising to say the least.
I'm personally torn apart with my mixed feelings about this camera, basically they're selling you a very well designed 2019 camera that should have been A1 OG. For photographers and reporters, it's almost perfect if not already perfect. But yes, the video capability is subpar when compared with competitors. However video isn't what I'm sad about. I'm sad about the subpar processor and software that limits the in cam post-processing.
It's much easier to transfer post processed JPGs to your phones, rather than transfering the RAW to phone and do all the heavy lifting there.
Interestinglly, A1's 14bit 20fps raw also translates to roughly 1billion pixels per second. My speculation might be wrong, but I'm not even surprised when I see that A9iii can only do 6k60fps (downsampled to 4k60fps).
For the Expeed 7 it can handle 8k60fps which is basically twice as fast as the BionzXR. However it doesn't come with the AI chip and I doubt whether it ever would have one in the future (it's not something that's plug and play, rather, it needs extra resources pre-allocated on chip).
The true king of processors right now however I think is the Canon DigicX, it has rocked 8K60fps@12bit already, very impressive.
