avenon-21mm-f2.8
YOSHIRO SHINKAWA JIPANG
The 21/2.8 Kobalux has 8 elements in 6 groups, f/stops from 2.8 to 22, 58mm filter size, 6 aperture blades, 7 1/2 oz, 66mm overall diameter x 48mm overall length (35mm mounted on camera), weight 7.5oz. Pictured on the CL is the 2nd version of the lens. A 3rd version was introduced in 2001 with half click stops and slightly closer focusing .The finder is bright and overly large to the point of being embarrassing, with a 39mm diameter. It has a projected brightline and parallax correction marks in the finder. The corners may not be visible wearing glasses. A better finder choice is probably the much smaller Cosina Voigtlander 21 brightline.
It's a well made lens, conveniently needing only 1/4 turn to go from infinity to the closest focusing distance of one meter. The barrel has Depth of Field scales for 2.8, 4, 5.6, and 8 as well as an IR mark. At F8, DOF extends from infinity to 1 meter!
