Hi would like to ask if this is common? some times i get not so sharp pictures even i use low ISO of 200-640 with shutter relatively fast for a 35mm f1.8 prime in broad day (~1/80-1/500), aperture f1.8-f3.2, i know the acceptable shutter for handshake is 1/focal length for full frames?not so sure with cropped sensors though..the occurence is around 1 or 2 in 30 shots..wonder if this has happen to you guys also?
