DESCRIPTION

The G-Claron is a lens of symmetrical design with six elements in four groups, optimized for 1:1 reproduction. The normally used range of linear magnifications is 5:1 to 1:5. The G-Claron may also be used for distances up to infinity by stopping down to f/22 or less. For photographic work the G-Claron can be used up to an angle of 64 degrees and is free from mechanical vignetting at f/16 or smaller apertures.
