I am selling a Canon 28mm F3.5 for Leica thread mount cameras. The condition is very good. The glass is clean, clear, fungus-free, scratch-free, and separation free. The focus and iris actions are smooth. There is either a bit of oil or minor scoring on the front iris blades, as is common on these lenses, but this minor has zero impact on use.
The 28/3.5 was Canon's sharpest rangefinder lens in this focal length and performs very well even by modern standards. Sold with what I believe to be the original rear cap.
Price: $325 plus insured shipping
I prefer payment by checks or money orders, although I accept PayPal.
