when was the twin lens reflex camera invented?
1947
the tlr camera was thus an evolution. using a reflex mirror to allow viewing from above also enabled the camera to be held much more steadily than if it were to be held in the hand. the same principle of course applied to slr cameras, but early slr cameras caused delays and inconvenience through the need to move the mirror out of the focal plane to allow light to pass to the plate behind it. when this process was automated, the movement of the mirror could cause shake in the camera and blur the image. the london stereoscopic co's "carlton" model is claimed to have been the first off-the-shelf tlr camera, dating from 1885.
