Nikkorex F |

35 mm camera, 135 mm objective, The Nikkorex F Camera had its own coupled meter, and a couple of
lenses made by Mamiya. This is a Nikkorex F, with the (Mamiya) Nikkorex-Sekor
35mm f/2.8, and with the Nikkorex coupled meter attached. The Nikkorex-Sekor
lens is not meter coupled in any way (and is semi-automatic), having a lever
for "cocking" the aperture which must be activated to reopen the
lens after each exposure. The meter can be used with such a lens, in which
case it is set to the film speed in use, is coupled to the shutter speed dial
only, and the needle's readout is an aperture to be manually set by the
photographer for that particular shutter speed. When used with a
"pronged" lens the lens is mounted with the f-stop set at f/5.6, in
which case it engages the "prong" of the lens with its own pin.
This couples the lens's aperture to the meter. The maximum aperture of the
lens is then set on a dial on the meter at a point which is just opposite the
film speed in use. This indexes the maximum aperture of the lens to the meter
and allows direct setting of the exposure with movement of either the shutter
speed dial or the aperture ring, or both, to match the meter's needle, in a
manner that the meter reflects both the shutter speed and aperture in use. |
