Table 19: Pike F-210 focal length vs. field of view
Note
Lenses
with
focal
lengths
<
35
mm
will
very
likely
show
excessive
shading
in
the
edges
of
the
image
due
to
the
fact
that
the
image
size
of
the
sensor
is
slightly
bigger
than
the
C-mount
itself
and
due
to
microlenses
on
the
sensor's
pixel.
Contact
your
Allied
Vision
distribution
partner
if
you
require
non
C-Mount
lenses.
