Minox B Spy Camera Complan Lens Original Leather Case & Measuring Chain
The Minox cameras project an image of 8×11 mm onto the negative. The film is in strips 9.2 mm wide, or less than one-quarter the size of.
Film, and unlike 35 mm film, it has no. This film strip is rolled up in the supply side chamber of a small twin chamber cartridge, with the film leader taped to a take-up spool in the take up chamber. The film strips can be up to 50 frames in length in Minox B cameras.
Early Minox B cameras were equipped with a four-element, three-group. Designed by ex-Leica lens designer. The Complan lens has a curved film plane, hence in these cameras the negative must be held in an arc to improve the edge-to-edge sharpness of the image.The Minox enlarger also holds the negative in this same curve. The late model Minox B, using the 15 mm f/3.5 four-element, three-group flat-field Minox lens, holds the negative flat. The advance was attributed by Rolf Kasemeier (Small MINOX Big Pictures 1971 edition) to new rare-earth element, high-index, low-dispersion, optical glasses becoming available (probably from Schott Glass, of Jena). Note that lens performance between old and new complan/minox lenses was rated by MINOX themselves as identical. Minox B cameras were equipped with a mechanical shutter.
When closed, the viewfinder and lens windows are protected. Complan lens are unit focusing lens, focusing from 8 inches (20 cm) to infinity through precision gear linked to a focusing dial on top of the camera. All Minox cameras, except the EC and MX, have a parallax correction viewfinder: when the focusing dial moves, the viewfinder moves in tandem to correct for parallax. The Minox B film counter counts up to 50. For mechanical Minox 8x11 cameras, a separate shutter speed dial sets the shutter speed from 1/2 to 1/1000 second, plus B and T. Above the viewfinder is a filter bar used to slide a yellow, green or an orange filter in front of the lens. Later Minox B cameras featured a honeycomb. For Minox B, the film advances each time the camera is closed, regardless of whether a picture is taken or not. Opening the camera causes the pressure plate to press the film into a concave or flat (depending on the model) surface to stiffen thin emulsions for better clarity. When the camera is closed, the pressure plate moves back from the film plane, thus allowing the film strip to move freely to advance to the next frame.
