"M42 28mm F2.8 Derek Gardner Automatic Lens, and how does it perform? The filter size (62mm) is awfully big for a 28 mm /f.28"
"Just used my new to me M42 Vivitar 28mm f2.8 today, which has a 62mm filter thread. Perhaps it is the brother or cousin of the Derek Gardner lens you mention above. Yes it is big - my equivalent Tokina m42 is 52mm filter size. The Vivitar has a kind of universal mount adaptor on it. Sound familiar? Labelled 'Wide Angle'. No auto/manual aperture switch but a wheel to manually stop down while metering and taking the shot. A bit awkward."
Both are Tokinas, of the first generation of Tokina automatic lenses, @1969-1975 or so.
The "Derek Gardner" is a fixed mount version.
The Vivitar has a T4 interchangable M42 (Pentax screw) mount. The M42 T4 mount has that %$(&% wheel thing. I disabled that wheel on mine, so I have an M42 T4 that is now manual only. Much better on DSLR.
I have the Soligor fixed M42 and T4 versions (both Soligor and Vivitar sold the same Tokinas), and a Sears M42. There are versions with 62mm and 58mm filters.
