[QUOTE="Don Kuykendall_RIP, post: 508518, member: 6277"] The reciprocal rule is based on the fact that at slower shutter speeds any slight camera movement will cause some motion blur in your photo.Fortunately the opposite is also true, in that the faster the shutter speed is the sharper your images are likely to be. the effective focal length of your lens is 100mm then your shutter speed should not be any lower than 1/100 of a second. So the basic formula looks like this: Shutter Speed = 1/focal length.
