Eliminating camera shake #photography

We have all had pictures where a slight blur totally spoils the image. Camera shake is always a problem and can be caused by the slightest vibration. I advised someone this week who was using a 300mm lens full frame lens on a crop sensor camera. It wouldn’t auto-focus and so she had to focus manually. I thought the problem was not just focusing but camera shake. It would have an equivalent focal length of 450 mm on a crop sensor camera, so camera shake would be amplified when she zoomed in. Generally speaking, a shutter speed of the inverse of the focal length is the minimum for eliminating camera shake. Vibration from a nearby heavy vehicle can cause a lot of camera shake and cause blur at 300mm.
