To reduce the size of cameras, the VHS-C mechanism uses a two-thirds size head drum (41.3 mm diameter instead of the original VHS drum size of 62 mm). The wrap angle is 270 degrees instead of VHS's 180 degrees.
To determine the size of the electrical drives, it is necessary to calculate the values of the intermediate tension or tensions. [19] The maximum tension difference ΔT across a single bridle roll is determined by the wrap angle α (in radians) of the strip around that roll, and the roll-to-strip sliding friction μ, i.e. [18]
One foot of standard 35mm film contains 16 frames, and a standard recording speed is 24 frames per second, or 1.5 feet per second; a 90-minute feature film shot in this way on conventional film stock is therefore equivalent to more than a mile and a half of footage.

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 ...
If the goal is to keep the shuttle during its orbits in a constant attitude with respect to the sky, e.g. in order to perform certain astronomical observations, the preferred reference is the inertial frame, and the RPY angle vector (0|0|0) describes an attitude then, where the shuttle's wings are kept permanently parallel to the Earth's ...

On a crop camera with APS-C/H size sensors, it only yields a cropped circular and full-frame image. A zoom lock is included which avoids leaving the focal length range of full coverage on crop sensor cameras. Nikon AF-S Fisheye Nikkor 8–15 mm f /3.5–4.5 E ED – designed for full-frame and FX cameras, this lens behaves identically to the Canon.
