When the mirror reaches the horizontal position it fires a focal plane shutter just in front of the film to make an exposure. Then, the light makes its way to a light-sensitive surface. zebra stripes, focus peaking); see note below. Its disadvantages could be reduced to one: price. They shoot as soon a. Can superimpose more complex data over the image (e.g. No, "single lens" means a single lens attached to the camera.

Why is there "single" in the term DSLR (Digital Single Lens Reflex)? Potentially smaller and lighter camera bodies and lenses (particularly wide angle lenses), Can zoom in to verify precise focus and depth of field, Can see (almost) exactly what the camera sees, even in low light. This was a big innovation, because previously, the photographer would focus, and then carefully replace the viewfinder's ground-glass screen with the recording media (glass plate or film-holder or whatever). These cameras offer the same advantages as a DSLR, that is, interchangeable optics and large sensors with which to obtain high-quality images, but without that mirror system of the SLR.
