Myth or fact?
In the 70s, a Zeiss designer attempted to "improve" the Planar formula and
result was a bad batch of Rolleiflex 2.8F lenses
This is from a well-known individual making after market components for cameras.
The early 50s bad 2.8 Tessar batch is well documented; First I've heard
anything about 2.8 Planars.
Comments?
