Canon FD 35-70mm f/3.5~4.5 bayonet mount
Canon AE-1 with self timer only
@ 35mm setting
Vignetting = C+ @ f/3.5, B @ f/5, A thereafter
Distortion = pronounced barrel
Aperture Center Corner
f/3.5 B C
f/5 A- B-
f/7 A B+
f/10 A- A-
f/14.5 B+ B+
f/20 B B
Notes: moderately high contrast at f/3.5 and f/5; high contrast at f/7 anf f/20; very high contrast at f/10 and f/14.5. Markedly lower performance in the corners at all three focal lengths tested, although a generally contrasty lens - but at the expense of resolution. Distortion typical of short, standard zooms with few elements.
This is a mild wide angle to short telephoto lens, considered to be usefull for most normal photographs.
