A cable-suspended camera system is a system of cables above or along an area to be filmed or videoed, over or along which an attached camera head travels to achieve required camera angles. There are two broad types cable-suspended camera systems: fixed-cable and moving-cable types.
Canon EOS (Electro-Optical System) is an autofocus single-lens reflex camera (SLR) and mirrorless camera series produced by Canon Inc. Introduced in 1987 with the Canon EOS 650, all EOS cameras used 35 mm film until October 1996 when the EOS IX was released using the new and short-lived APS film.
A fixed position camera removes these components, relying solely on digital translation of the high detail camera image. Fixed-view fisheye cameras have a bowl-shaped 360-degree view. When mounted overhead pointing straight down, part of the viewed space appears sideways or upside-down on the VMS. For these cameras, the digital PTZ may also ...
Fixed focus can be a less expensive alternative to autofocus, which requires electronics, moving parts, and power.Since fixed-focus lenses require no input from the operator, they are suitable for use in cameras designed to be inexpensive, or to operate without electrical power as in disposable cameras, or in low-end 35 mm film point and shoot cameras, or in cameras featuring simple operation.
There is a cost to this however: slightly less light reaches the film, as some is always being directed up to the viewfinder and optical quality loss. By the time of the release of the next generation EOS-1V, considerable technical improvements to the standard camera design meant that Canon no longer offered RS model variants.
The term "fixed pattern noise" usually refers to two parameters. [1] One is the dark signal non-uniformity (DSNU), which is the offset from the average across the imaging array at a particular setting (temperature, integration time) but no external illumination and the photo response non-uniformity (PRNU), which describes the gain or ratio ...
For film cameras, a motor drive to advance the film automatically. For film cameras, different camera backs, e.g. large capacity for bulk film, or data back or datebacks for recording exposure and date information. Add-on correction or magnifying lenses to help focusing or composition through the viewfinder.
With its maximum aperture over its zoom range being F2.8-5.8, and with its sensor smaller than Canon APS-C sensor, the G1 X camera-lens system can be compared to the APS-C DSLRs using the Canon EF-S 18-55 mm f/3.5-5.6 IS II SLR Kit Lens: the G1 X is a little faster (wider aperture) at the wide angle and comparable thereafter, but with a longer ...
