Re: lowest reliable handheld shutter speed?

Hi Mike: That is a pretty difficult question to answer in a few words. Motion blur is a function of the lens focal length and shutter speed combination and whether the lens has OS and whether the subject was in motion. When I have time I will mine the files I shot with the SD1 and see if I can find a consistent trend. This would be good information for me to have a handle on for future shooting. I know in one instance I took 2 shots back to back and one was tack sharp and the other on had significant motion blur (obviously operator error). In another case it was the OS being confused by the subject moving during the exposure leading to a lot of blur.

As far as other Sigma cameras: I had no or very little problem with motion blur with the SD9; The SD14/15 required me to be more careful to avoid motion blur, although I did not think it was a significant issue (I may have to re-evaluate that issue); Maybe, because I was looking for pixel level sharpness in the SD1, I did notice motion blur in about 30% of my shots. I would say, base on my limited sample, that the SD1 is more sensitive to motion blur then the SD14/15.
