Hello, Since purchasing a new EOS-1ds MarkIII, I have noticed that my images are quite blurry when shooting handheld, at speeds that all other cameras have had no problem with- 1/60th and 1/80th. In fact, the only time I have gotten tack sharp images is when using strobes. Otherwise, they are at least a little bit soft. So I am wondering what the slowest shutter speed is for shooting handheld with this camera, and if this is normal, or if there may be some problem with the camera. Thanks!
