Thanks smf, this is the screen name I usually use on forums when a real name isnt required.
The 200mm was a real find! I got it in a "grab bag" filled with old kodak mailers, wratten filters, a roll of Kodachrome

, etc. The owner would only sell the whole bag which also included an 80-250mm Asanuma zoom.
Both lenses are in excellent condition, but are M42 Pentax screw mount. My research indicates I
can adapt these to my EOS, but just because it fits doesn't mean it will focus properly. I've read some lenses have problems focusing to infinity and such.
Fortunately, adapters seem comparatively cheap and its not a big loss if it doesn't work. I won't know until later this week.
