Canon EF 28 mm f/2.8 Manual
The CANON LENS has been acclaimed by many experts as the
finest lens in its class today.
It is a precision instrument as carefully constructed as the CANON
CAMERA itself. Treat it with respect. It has been accurately set
and aligned by hand and final settings arc made with microscopic

alignment instruments. ALL CANON LENSES are rigidly checked
for resolving power sand lens aberration
curvature of field, distortion, chromatic and color definition. Any
lens that does not come up to Canon's very high standards in any
one of these tests is immediately discarded. According to the charac-
teristics of the lenses, they are coated either in purple, magenta, or
amber in order to obtain true color for color photography.
Do not endeavour to open up the lens. If there is anything wrong,
return the lens to your dealer who will forward it to the manu-
facturers for their attention.

spherical, coma, astigmatic,
