Olympus OM-2 - Zuiko Interchangeable Lens Group

ZUIKO INTERCHANGEABLE LENS GROUP
45
One of many advantages of the single lens reflex type of
camera is the large variety of interchangeable lenses available.
The Zuiko Interchangeable Lens Group (designed and manu-
factured by Olympus) comprises 33 lenses including those
now in the course of development . Zuiko lenses have always
enjoyed a high reputation in photographic circles - new
design
technology has made possible a new series of inno-
vative, high performance lenses. These lenses have a host of
special features including a new const r uction that compen-
sates
for close focus aberrations, increased aperture ratio in
the wide angle lenses, and reduction in telephoto lens size
and
weight . The OM System adopts 49mm filters for most
lenses from 21 mm to 200mm. As part of the OM System
design all
the lenses now offer higher performance in small
configurations. Olympus has produced lenses for micro-
scopes for many years and the new Zuiko lenses benefit
from this scientific experience . See the "OM System Zuiko
I nterchangeable Lenses" instructions for further informa-
tion.
