Dioptric Adjustment Lenses
Attaching a Dioptric Adjustment Lens E to the
viewfinder
eyepiece

fo
cusing
easier
without
glasses
for
near-

far-sighted
users.

built-in
viewfinder

eyesight

adjustment from +3 to -4 diopters. Choose the
one which is closest to your eyeglass pres

necessary

attachment
to
this camera.
