Both mirror and aperture mechanisms working correctly (no canon cough).
Lens
focus
is smooth, focuses correctly,
aperture blades are clean and fully close, some dust and light coating wear on the elements (highlighted with strong lighting), nothing that would affect picture quality.
Light body wear (check pictures), some particles in the
viewfinder glass and focus screen (highlighted
with strong lighting), nothing noticeable in use or that would affect picture quality.
Requires 1x 4LR44 battery.
I have other canon fd lenses available, send me a message if you're interested.
