Technology for holding an exposure setting from one scene to another. [4] AF: Autofocus. The lens is focused automatically by means of the camera's hardware and firmware, to obtain optimum sharpness of an image. [4] AF-L or AFL: Autofocus lock. Locks a particular focus setting, preventing refocusing if the scene changes. [4] AoV: Angle of view ...
In most digital cameras, by default autofocus is only activated (AF-on) when the shutter button is pressed halfway down, which helps to preserve battery life. However, some photographers find that having AF-on and the shutter release on the same button makes it harder to establish the correct focus point, or hold it once the desired point is ...
Image sharpness is also enhanced by the lens shift image stabilization system that reduces the effects of camera shake, especially at the longer zoom settings. The 1/2.3-inch 16.2 megapixel CMOS sensor in the S9200 is back-side illuminated to ensure the best possible results right up to the maximum ISO sensitivity of 12,800. The S9200 can start ...
Cinema EOS is a branch-off from the existing EOS line of cameras that dates back to 1987 with the introduction of the analog Canon EOS 650.With many Canon DSLRs adding motion video capabilities, starting with the Canon EOS 5D Mark II in 2008, [2] [3] Canon decided to focus on making cameras specially designed for motion video instead of just producing still video cameras with some motion video ...
The Minolta 7000, released in 1985, was the first SLR with an integrated autofocus system, meaning both the AF sensors and the drive motor were housed in the camera body, as well as an integrated film advance winder — which was to become the standard configuration for SLR cameras from this manufacturer, and also Nikon abandoned their F3AF ...
An entry-level camera, exposure mode was program AE only, with a high-speed program option, no Creative Expansion Card support. An even more basic Maxxum, this camera was basically for the point-and-shoot user that wanted a system SLR camera with interchangeable lenses and more powerful flashes, but did not want the features on, or did not want to pay for the 5000i, 7000i, 8000i cameras.
Because the process is mechanical, however, and relatively brief, shutter lag in film cameras is often only noticeable (and of any concern) to professionals. SLRs have slightly longer shutter lag than rangefinders, because of the need to lift the mirror. Point-and-shoot film cameras often have significant shutter lag.
An Arri 35mm film camera with a follow focus mechanism mounted to a zoom lens. Pulling focus using a follow focus device. A follow focus is a focus control mechanism used in filmmaking with film cameras and in television production with professional video cameras. It helps the camera operator be more efficient and precise.
