Originally posted by amoringello I'm wondering what percentage of people can hold the camera steady enough for the SR to work at a less than 1-pixel resolution for a one second hand held shot.
Even with very high shutter speed, the total process to take four images is nearly four seconds.
I can get sometimes useable images at one second exposure (compared to not using SR), but I'd hardly let someone view them full size... i.e. the sensor is not able to make a perfectly steady image over that time range.
This just seems like snake-oil to me, and I don't see where a heaver or lighter lens isn't going to help much.
I don't think it takes that long to actually shoot the images, although the processing does take a bit of time after the images are a shot, you don't have to hold the camera still during that time period.
I think the point with this hand held pixel shift is that the camera is not still between shots. Rather the camera is going to do some type of auto alignment in camera and fill in details between images from the other three images shot. Pentax says it will be 70 percent as effective as traditional pixel shift, which is still pretty decent. My guess is that it will reduce noise quite a bit, but not improve resolution quite as much.
There are guides to doing this type of super resolution shooting outside of the camera.
