The 250mm f/5 lens interlocks with the
rangefinder from 20ft (7m) to infinity. When
photographing at a short distance, focus by
directly observing the ground glass focusing
screen or by setting the lens distance scale
to the actually measured distance (by tape
measure) or the distance measured visually.
Regarding the black type and the chro-
mium type lens, the 100 mm f/3.5 and 150 mm
f/5.6 lenses have different filter sizes and
hood attachment sizes. When purchasing
filters, clearly indicate the filter diameter;
when purchasing hoods, clearly designate
the type of lens and its focal length.
The picture angle marked with an asterisk (
*
) is that when photographing through the
Polaroid film pack format 100 or 660 series.
The black type lens has a black-finished lens barrel scale ring.
The chromium type lens has a chromium-plated shutter speed dial.
