The A12 50mm GR Lens has a focal length of 50 mm. Part of its appeal is that it gives a natural visual field with an angle of view nearly the same as the human eye. The 50 mm focal length is one of the most basic for candid photography. Compared to a wide-angle lens, a suitable distance is maintained from the subject, and the photographer is able to chat with the subject and elicit natural expressions to capture the person in a candid way without undue attention being paid to the camera. GR LENS A12 50 mm is also a macro lens. The photographer can enjoy close-up photography to a maximum magnification of 1/2x and, from a wide open aperture setting, obtain images with excellent sharpness and high contrast and resolution to the edge.
