With
an angle of view of 47 degrees, this lens is equivalent to a 50mm lens
in 35mm format. This is the standard lens for the format, with a field
of view approximating natural human sight. It is the most
general-purpose lens in the series, and works well in various
applications for close or distant subjects. Packing high performance
into a compact, lightweight configuration, it is well corrected for
distortion, producing a natural, well-balanced image.
