Zebra patterning, or zebra stripes, is a feature found on some prosumer and most professional video cameras to aid in correct exposure. When enabled, areas of the image over a certain threshold are filled with a striped or cross-hatch pattern to dramatically highlight areas where too much light is falling on the image sensor. [1] [2]
Manual focus is generally in release priority – AF is neither detected nor set. Note that these "priority" modes should not be confused with the same word in exposure modes. Focus priority can also be used for the trap focus trick: to take a picture only when a subject hits a focus point, by using AF to detect focus but not set it.
The AF point was set to the eye of the toy; the camera has been able to produce a good exposure, by not being fooled by the strong back lighting of the out of focus areas. This mode is also called matrix , evaluative , honeycomb , segment metering , or esp (electro selective pattern) metering on some cameras.

The reciprocal of exposure time in seconds is often used for engraving shutter settings. For example, a marking of "250" denotes 1/250". This does not cause confusion in practice. The exposure time and the effective aperture of the lens must together be such as to allow the right amount of light to reach the film or sensor. Additionally, the ...

The first true zoom lens, which retained near-sharp focus while the effective focal length of the lens assembly was changed, was patented in 1902 by Clile C. Allen (U.S. patent 696,788). [ 7 ] : 155 An early use of the zoom lens in cinema can be seen in the opening shot of the movie "It" starring Clara Bow, from 1927.
