Compared to mainstream cameras that typically have non-interchangeable lenses and/or focal plane shutters operated from the camera body, another difference with medium and especially large format lenses is that they are typically interchangeable in a very simple manner, being mounted in a "lens board", and include a shutter just in front behind ...
Many medium-format and most large-format cameras, however, have interchangeable lenses each fitted with a central shutter. A few interchangeable-lens cameras have a behind-the-lens leaf shutter. Large-format press cameras often had a focal-plane shutter. Some had both a focal-plane shutter (for lens interchangeability) and a lens with central ...
Focal-plane shutters can be built into the body of a camera that accepts interchangeable lenses, eliminating the need for each lens to have a central shutter built into it. Their fastest speeds are either 1/4000 second, [ 2 ] 1/8000 second, [ 3 ] [ 4 ] or 1/12000 second; [ 1 ] much higher than the 1/500 second of the typical leaf shutter .
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 ...
Cross-section of a typical retrofocus wide-angle lens. Extreme or ultra-wide-angle lens - a wide-angle lens with an angle of view above 90 degrees. [4] Extreme-wide-angle lenses share the same issues as ordinary wide-angle lenses but the focal length of such lenses may be so short that there is insufficient physical space in front of the film ...
The most common large format is 4×5 inches (10.2x12.7 cm), which was the size used by cameras like the Graflex Speed Graphic and Crown Graphic, among others. Less common formats include quarter-plate (3.25x4.25 inches (8.3x10.8 cm)), 5×7 inches (12.7x17.8 cm), and 8×10 inches (20×25 cm); the size of many old 1920s Kodak cameras (various versions of Kodak 1, 2, and 3 and Master View cameras ...
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch.
These cameras could also be used with "between-the-lens" shutters mounted to the front lens board as more typically seen on large format cameras. [4] The Speed Graphic became even more popular than the Graflex Reflex as a press and sports camera, so much so that to this type of classic press camera features in the masthead of the New York Daily ...
