FOREWORD
The
PC-Nikkor
35mm f/2.8
is a retrofocus-type
perspective control (PC) lens with
an optical
construction of 7
elements
in 7
groups.
The
im
age
circle
of th
is
lens
is wider than regular
35mm
wideangle
lenses providing
a coveri ng
angle of
78°
; thus
image quality is insured
even
when
the
lens
is shifted.
The
lens
barrel
can
be
shifted up to 11
mm
off-axis and rotated 360
0
with click-stops every
30
0
for complete
image
control. The
PC-Ni
kkor is ideally suited for
architectural
and
commercial
photography,
enabling the photographer to
properly
frame
the
subject
without tilting or angling the
camera-
and the photographer
has
the added
convenience of thru-the-lens viewing and meter-
ing
for greater ease of operation.
It is
also
possible
to
take
panoramic
shots
.
If used
with a
Nikon
camera having inter-
changeable
focusing
screens, the
Type
E or
E2
with
its
etched
horizontal
and
vertical I ines is
-recommended. All aberrations
have
been well
corrected, especially coma and curvature of
field
,
so that
image
quality is truly outstanding.
