Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.
This is a list of Leica cameras.Leica Camera AG is a German optics company which produces Leica cameras.The predecessor of the company, formerly known as Ernst Leitz GmbH, is now three companies: Leica Camera AG, Leica Geosystems AG, and Leica Microsystems AG, producing cameras, geosurvey equipment, and microscopes, respectively.
Lenses offered for the S2 include Summarit-S in normal (70mm), wide-angle (35mm), and macro (120mm) varieties, and Tele-Elmar (180 mm) portrait-length telephotos; these are available in versions that feature integrated multi-leaf blade shutters ("Central Shutter", or CS), in addition to the focal-plane shutter in the camera body, to enable ...
The Leica CL has a vertical-running focal plane shutter, with cloth curtains, giving ½ to 1/1000 speeds. There is a through-the-lens CdS exposure meter mounted on a pivoting arm just in front of the shutter, like the Leica M5. The exposure is manual and the shutter is mechanical. The shutter speeds are visible in the finder.
The Leica copies originate from the Leica camera that was launched by Ernst Leitz, Wetzlar in 1925, using the Leica 39mm screw mount of 26 threads per inch (25.4 mm), and the standard 35mm film. The design was carried out by Oskar Barnack , beginning in 1913 by building a camera for 24×36 mm negatives that by now is called the Ur-Leica, or ...
The Leica R3 was a 35mm SLR camera by Leica and the first model of their R series.. Leica launched the Leica R3 in 1976. It was the successor of the Leicaflex SL2, and was developed in cooperation with Minolta, together with the Minolta XE bodies.
Earlier aerial cameras, from the World War I era, included the Kodak K1, with focal plane shutter, the Fairchild K3, K3A, K3B etc., with in-lens shutter to eliminate distortion, K5 etc., some of which used individual glass plates, some individual sheet film, and some roll film.
The focal plane shutter consists of a rubberized flexible curtain with slits of varying widths that cross the film plane at speeds determined by the tension setting of the spring mechanism. There are 4 slits with widths of 1/8 in, 3/8 in, 3/4 in, 1 1/2 in and “T” (T = “time” setting, used when lens diaphragm shutter is used to control ...
