Updated: April 6, 2001
Note on tests: Mirror and diaphragm prefire indicates that the mirror was raised and the lens stopped down well prior to exposure, thus controlling two of the three major vibration sources in an SLR.
For comparisons to Olympus
OM System lenses, manual focus-able point and shoot cameras with adjustable
exposure controls and other competing SLR camera manufacturer lenses (esp.
Nikon and Minolta), see:

Note: incorporates

green tinge to the pictures. Best use as an exceptional quality lens for
black and white photography, since it doesn't match the color of other
Canon FD lenses and will color cast color slides. Very high contrast at
all but f/5.6 and f/8 where it is extremely high. Optimum aperture f/5.6.
