carefully to make sure that you have the sharpest possible focus. To
achieve a very sharp focus, consider using a focusing magnifier. These
devices are readily available from your local camera store.
If you can not get a sharp focus, check to see if your subject is closer
than the near focus distance indicated in the 'Technical Specifications"
section.
NOTE; Due to the fast f/ratio of this lens, slow films should be used
when shooting under normal, daylight conditions.
Storing Your SS80 Spotting Scope
To minimize the need to clean your spotting scope, replace all lens
covers after use. Your spotting scope can be left on a tripod for
display purposes or returned to its canying case. Since the rear cell is
not se^ed, the eyepiece or plastic cover should always be placed over
the opening in the rear cell when not in use. This will prevent con¬
taminants from entering the optical system.
