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 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.
Though the prototypes received mixed reception, Ernst Leitz decided in 1924 to produce the camera. It was an immediate success when introduced at the 1925 Leipzig Spring Fair as the Leica I (for Leitz camera). The focal plane shutter has a range from 1/20 to 1/500 second, in addition to a Z for Zeit (time) position.
Focal-plane shutters expose using two curtains that cross the sensor. The first one opens and the second curtain follows it after a delay equal to the nominal shutter speed. A typical modern focal-plane shutter on a full-frame or smaller sensor camera takes about 1 ⁄ 400 s to 1 ⁄ 300 s to cross the sensor, so at exposure times shorter than ...
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 ...
Focusing can be manual, by twisting the focus on the lens; or automatic, activated by pressing half-way on the shutter release or a dedicated auto-focus (AF) button. To take an image, the mirror swings upwards in the direction of the arrow, the focal-plane shutter opens, and the image is projected and captured on the image sensor. After these ...
This camera had a leaf shutter, but two years later came the Shinkoflex, a 6×6 camera made by Yamashita ShÅkai, with a focal-plane shutter and interchangeable lenses. [13] However, Japanese camera makers concentrated on rangefinder and twin-lens reflex cameras (as well as simpler viewfinder cameras), similar to those of the Western makers.
