Turns out single-lens reflex (SLR) cameras have a flaw in their design that leads to more camera shake. Camera shake is of course bad for photography, because even the tiniest movement occurring while acquiring an image leads to lower-quality pictures. Ever been frustrated with blurry pics caused by hands that can’t keep still? That’s camera shake in action.
Anyways, the classic design of an SLR causes camera shake—even if said camera is perched securely on a tripod. That’s because in an SLR, the mirror which allows the user to see the image literally through the lens flips up when the shutter is pressed, allowing the camera’s sensor or film to save the picture. Unfortunately, that action also creates vibrations that cause camera shake and lead to lower-quality pictures, no matter how small these vibrations are. Read more
