Subject: re: Vivitar 135 1.5
I recently came across the Aug/Sept 1967 edition of Camera 35, which
includes a brief review and test of the Vivitar 135 f/1.5 T-mount on page
57.
The following info may by useful:
Reported resolution:
Center Edges
f/1.5 24 17
/2.0 28 24
/2.8 28 24
/4.0 34 28
/5.6 40 34
/8.0 48 40
/11.0 56 48
/16.0 68 48 * Max Res
/22.0 56 40
I don't know if the rated resolution is lines per mm, or inch, but it is
interesting that the lens apparently doesn't reach maximum resolution until
f/16
Dimensions: 5" long, 4" wide, 4lb,8oz
(Vivitar ad in the same magazine says: 5.5" by 4", 4lb, 3 oz
7 elements, 6 groups, min focus 6 feet
Lastly, the article claims the lens was originally made for NASA, and that
it lists for less than $600.00
keep up the amazing work, hope this helps.
