Photo Eyepieces F K
The new photo eyepieces F K are specially designed for photo-
micrography with the Olympus Photomicrographic System Camera Model
PM-10 (optional). The eyepiece powers available are 2.5x, 3.3x, 5x
and 6.7x. Each magnification is computed to focus an image at a projec-
tion length of 125mm - the same plane as the 35mm film plane, thus
compensating spherical aberration. The respective magnifications
are engraved on the
F
K eyepieces: Total magnification of a picture
when the F K eyepiece is used. is formulated as follows:
Total magnification with 35mm film = Objective power x FK eye-
piece power.
The formula below, however. will be applied in case the camp.ra
adapter with relay lens, model PM-D L, is used for larger format
camera backs:
Total magnification of.large format picture
=
Objective power x FK
eyepiece power x3.
