Well, a step towards the right direction would probably be to design the camera so that portability (compactness and lightness) are overriding priorities.
I believe -- without having anything concrete to go on but assumptions -- that it should be possible to achieve better cooling of the sensor by sacrificing some weight and size.
Sadly, one reads too little about the intrinsic downsides of mirrorless cameras and the solutions they often imply (e.g., OSPDAF).
One could forgive some of the press to gloss over some of the more technical downsides, if they didn't make a fuzz about issues that probably have a smaller visual effect.
Originally posted by Not a Number I wonder if the video mode sensor temperatures is part of the reason why Ricoh is reluctant to re-implement mechanical SR for video.
Non-stabilised video operation should heat up the sensor just as much.
If Ricoh were concerned with image noise, they'd have to exclude or limit the use of video as such (including extended use of LiveView).
I suspect the real reason is that their sensor-based image stabilisation is optimised for still photography. For the latter scenario it is not important to achieve smooth transitions between corrective movements, on the contrary, jerky movements can help to increase the effectiveness of the mechanism. I think it is likely that if Ricoh wanted to support proper video stabilisation, they'd have to come up with a different stabilisation algorithm that yields good results during continuous operation.
I've read that Sony's video stabilisation doesn't (always?) yield pleasing results, so perhaps it is this kind of performance that Ricoh does not seem good enough for video stabilisation?
