Re: 20mm age

I bought my first V20/3.8 in 1972 and all my resources (see one in a post below) also indicate 1970 as start of production for that lens.

Hi Alex,

I think the Vivitar 20/3.8 and 19/3.8 are different lenses. (This is confused by Cosina apparently having sold the Vivitar 19/3.8 as a Cosina 20/3.8.)

The Vivitar 20/3.8 is listed as having 9 elements in 7 groups, weighing about 370 g, having an 82 mm filter thread and a correspondingly large front element, 6 aperture blades, and has serial numbers that start with 22 (Kino).

The Vivitar 19/3.8 is listed as having having 8 elements in 8 groups, weighing about 180 g, having a 62 mm filter thread and a correspondingly smaller front element, 5 aperture blades, and has serial numbers that start with 9 (Cosina).

Regards,

Alan
