The Sony Cyber-shot
DSC-R1 is a bridge digital camera
announced by Sony
in 2005 (and discontinued in 2006). It featured a 10.3 megapixel APS-C
CMOS
sensor (21.5 × 14.4 mm), a size typically used in DSLRs
and rarely used in bridge cameras (which usually use 2/3" (= 6.6 × 8.8 mm) or 1/1.8" (= 5.3 × 7.1 mm)). This was the first time such a large sensor was incorporated into a bridge camera. Besides the APS-C sensor, R1 also featured a 14.3–71.5 mm Carl Zeiss Vario-Sonnar T* lens, providing for an angle of view
equivalent to 24–120 mm on a full frame camera.
Cyber-shot
Cyber-shot is a line of digital cameras made by Sony. The first cyber-shot was made by Sony in 1996. The Cyber-shot range is well known for its proprietary InfoLithium battery pack, the trademark Carl Zeiss lenses, and overall design. Also, all Cyber-shot cameras accept Sony's proprietary Memory...

Bridge digital camera
Bridge cameras are cameras which fill the niche between the single-lens reflex cameras and the Point-and-shoot camera. They are often comparable in size and weight to the smallest Digital SLRs , but almost all digital bridge cameras lack an optical viewfinder system...

Angle of view
In photography, angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view....

Advantages
Compared to a standard DSLR the Sony R1 has the following advantages:- since there is no mirror between the sensor and the lens, the lens can be positioned closer to the sensor, which improves the performance at wide angle

and LCD screen is bright and the light is amplified. An optical viewfinder instead does not amplify the light, so that it becomes difficult to frame and manually focus when there is not sufficient light. - technically no dust problems, since the R1 has a fixed lens, though dust can enter the lens itself while zooming
- silent operation, as there is no swinging mirror or physical shutter system
- as there is no shutter system there is essentially no limit to flash sync; photographs can be taken in broad daylight with fill flash at speeds of 1/1,000th of a second or faster
- fewer movable parts, therefore greater reliability
Disadvantages
and the following disadvantages:- no interchangeable lenses: the supplied lens only covers the 24–120 mm zoom range.
- no optical viewfinder. Furthermore there is some small time shift, i.e. the image appears with a small delay.
- Low frame rateFrame rateFrame rate is the frequency at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems...
