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.
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 Konica Auto-Reflex of 1965 was the first focal-plane-shutter auto exposure 35mm SLR; hence the name. [10]: 12 This model and its rarer, meterless companion the Konica Auto-Reflex P are the only models where "Auto-Reflex" is hyphenated. These are also the only two SLRs that ever offered a choice of full- or half-frame exposures, switched by ...
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 ...
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 ...
In 1964 Leitz introduced its first single-lens reflex camera, the Leicaflex also known as the Leicaflex Standard. This was a response, albeit reluctantly, to the rising popularity of the SLR format. Ludwig Leitz, head of the company was urged to begin development by photographer Walther Benser back in 1955. This was due to Benser's opinion that ...
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 ...
