Re: Panasonic GH3 review

Flash sync speed (if the curtain could move over the sensor reliably at 1/200 of a sec they would have specified that not 1/160) and the number of rows.

On the CPU side it's a pain getting a processor to address stuff (row resets) and do reliable and consistent timing at those speeds (although I know no details of the working of the Venus engine). Interrupts can be a tricky and dedicating a CPU to nothing else is unlikely to be an option when something exciting like taking a photo is happening (especially in an existing design). You ideally want it done on-sensor or at least having a dedicated timer in the CPU connected up to some circuitry on the sensor to make it easier. IMHO of course.
