Optical condition: Former hazing of the front element was removed many years ago, this is a very common issue with these collapsible Elmar lenses and while sharpness shouldn't be affected there may be a loss of contrast and slightly more proneness to flare without a hood in extreme lighting situations. Internal and rear elements are very clean with only debris visible inside. Mechanical condition: Very smooth focusing and pleasantly smooth aperture with nice clicks. Be sure to check out the pictures for more details as they can explain things than I ever could and as always feel free to send me a message if you have any questions.
