A tight shutter angle will constrict motion blur. A wide shutter angle will allow it. A 180° shutter angle is considered normal. So for instance, at 24 fps the frame interval value is 0.04167 second ( = 1 ⁄ 24). Using an exposure time of 1 ⁄ 50 second gives a shutter angle value of 173°, very close to 180° (normal motion blur effect).
35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
The Olympus Pen F, Pen FT and Pen FV are very similar half-frame 35 mm single-lens reflex (SLR) cameras with interchangeable lenses produced by Olympus of Japan between 1963-1966 (Pen F), 1966-1972 (Pen FT) and 1967-1970 (Pen FV). The original Pen F has a double-stroke film advance and a distinctive logo rendered in a gothic font.
A drop shutter-like mechanism with an adjustable slit was used at the focal plane of an apparently one-off William England camera in 1861 and this is considered the first FP shutter of any kind. [35] If the lens on a single curtain FP shutter camera has its lens cap off when the shutter is cocked, the film will be double exposed when the blind ...
Each exposure required the photographer to change the film holder, open the lens shutter, cock the focal plane shutter, remove the dark slide from the inserted film holder, focus the camera, [a] and release the focal plane shutter. Conversely, if the lens shutter were used, the focal plane shutter (on the Speed Graphic and Pacemaker Graphic ...
The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a ...
Some had both a focal-plane shutter (for lens interchangeability) and a lens with central shutter (for flash synchronisation); one shutter would be locked open. Film cameras, but not digital cameras, with a central shutter and interchangeable lenses often have a secondary shutter or darkslide to cover the film and allow changing lens in mid ...
It has a 28mm f/3.5 Zuiko lens. Its shutter settings are 25, 50, 100, 200, B; its aperture range from 3.5 to 22. The back is removed completely for film loading and unloading. The Pen S is almost the same camera, with the following shutter settings: 8, 15, 30, 60, 125, 250, B. It existed in two versions, with a 30mm f/2.8 lens or a 28mm f/3.5 lens.
