Cosmorex SE Manual De Propietario

•When shooting with a telephoto lens, use the fastest

possible shutter speed. Remember that telephotos
magnify the image - and magnify any movement of
the camera (or subject) proportionately. As a
general guide try to use a minimum shutter speed
roughly equivalent to the focal length of your lens -
for example, 1/125th second for a 135mm lens.

W

hen using "long" telephotos (200mm or greater

focal length), you may notice that the top edge of
the viewfinder appears to darken. This phenomenon
is caused by the fact that, with ultra-telephoto
lenses, some of the light rays pass under your
camera's reflex mirror, and thus are not reflected
into the viewfinder.

However, your film image is not affected as all
light rays reach the film plane when the picture
is taken.

*For telephoto shots in general, try to find ways

of "bracing" yourself to hold your camera extra-
steady during exposure. If you're shooting over a
fence, you might rest both elbows on the top
post. Or, you could brace your body against a
wall during the exposure. Wherever you are, try
to find the position that gives your camera and
lens the best support. This slight additional
effort will pay off in sharper, clearer telephoto
pictures.
