Though it all depend on indivdual holding skill but by sing 35mm Camera minimum shutter speed rule of thumb, the minnimum speed should not be slower than the reciprocal of the focal length. May I know how does this apply to Digital Photography? For example a lens @ 100mm focal length in 35mm film camera is actually 150mm on a DSLR (taking into consideration of 1.5x factor). Hence, should the minimum shutter speed be 1/125 or 1/250 for the DSLR? :dunno:
