•With wide-angle lenses, you benefit from an
expanded "depth-of-field" range. (This means
that more objects in front of, and in back of,
the subject will appear sharp in the final
photograph.) Since more objects
are in focus at a given distance, focusing may be more
difficult than with standard or telephoto lenses, and
the microprism "spot" in your Cosmorex viewfinder
may not disappear entirely. This does not indicate
any defect in your camera or lens! Focusing with
wideangle lenses is often easier if you first set the
lens to the minimum focusing distance, then raise
the camera to your eye and turn the focusing ring as
quickly as possible until the
image appears sharpest. (if you start with the lens
at or close to the correct focusing distance, or
hold the camera to your eye for a long period, it
will probably be more difficult to distinguish the
point of sharpest focus.)
W
hen using wide-angles, you may note an ap-
parent darkening of the edges of the viewfinder.
This effect takes place due to the different light
path of such lenses and has no effect on your
final print or slide.
