Beat the shakes

BLURRED shots caused by camera-shake are a common problem. To avoid this in handheld photography, the rule of thumb is that you need a shutter speed that’s at least the reciprocal of the effective focal length. For example, at a zoom setting of 50mm on cameras that have an APS-C sensor, like the 77D and 800D, the 1.6x crop factor gives an effective focal length of 80mm. You’d therefore need a shutter speed of at least 1/80 sec for consistently sharp handheld shots. Lenses with image stabilizers allow slower shutter speeds, but to freeze moving subjects, you’ll need faster shutter speeds. In dull lighting, use the Auto ISO feature or manually select a higher ISO.
