Zoom lenses are often described by the ratio of their longest to shortest focal lengths. For example, a zoom lens with focal lengths ranging from 100 mm to 400 mm may be described as a 4:1 or "4×" zoom. Typical zoom lenses cover a 3.5× range, for example 24–90 mm (standard zoom) or 60–200 mm (telephoto zoom).
70 mm film (or 65 mm film) is a wide high-resolution film gauge for motion picture photography, with a negative area nearly 3.5 times as large as the standard 35 mm motion picture film format. [1] As used in cameras, the film is 65 mm (2.6 in) wide. For projection, the original 65 mm film is printed on 70 mm (2.8 in) film.
The development of this camera started in 1983. The goal was to design a 65 mm movie camera, which was quiet enough to fit sync sound productions and had a similar ergonomy to 35 mm cameras, to answer the growing demand for 65 mm cameras. Other 65 mm cameras had noise production of up to 50 dBA, which made sound recording impossible. [1] The ...
The camera aperture needed to be set at f/6.3 for this lens to work as intended,(Filter diameter: 30.5 mm) 70 mm f/2.8 telephoto lens (equiv. 140 mm),(Filter diameter: 49 mm) 20–40 mm f/2.8 zoom lens (equiv. 40–80 mm). This lens extended for wider focal lengths and shortened towards the telephoto end, (Filter diameter: 49 mm)
The camera's features were fairly impressive at launch including a 10x optical zoom, a 5.1-megapixel CCD imaging sensor as well as a host of manual settings. The manual settings which the s5200 featured allow much control over the image, such settings like TTL metering, ISO, flash, Macro, White Balance and Red Eye Reduction could be manipulated.
The Fuji GX680 has quite large physical dimensions for a medium-format camera, but compared to the typical monorail/studio large-format camera, the Fuji GX680 is more compact. Although the Fuji GX680 was designed for studio work due to its size and weight, a neck-strap was offered for mobile work.
In everyday digital cameras, the crop factor can range from around 1 (professional digital SLRs), to 1.6 (mid-market SLRs), to around 3 to 6 for compact cameras. So a standard 50 mm lens for 35 mm photography acts like a 50 mm standard "film" lens even on a professional digital SLR, but would act closer to a 75 mm (1.5×50 mm Nikon) or 80 mm ...
Cameras which have been modified from the original standard 16mm (double-perforartion) to accept Super 16 (single-perforation) film may experience vignetting at the widest zoom setting with stock Meteor lenses. The camera has a single pulldown claw and no registration pin. At 24 frame/s, the Krasnogorsk-3 will run for about 25 seconds on a full ...
