The Sony
Cyber-shot DSC-R1 is a
bridge digital camera
A bridge camera is a type of camera that fills the niche market, niche between relatively simple point-and-shoot cameras and interchangeable-lens cameras such as mirrorless cameras and single-lens reflex cameras (SLRs). They are often compar ...

sensor (21.5 × 14.4 mm), a size typically used in
DSLRs and rarely used in bridge cameras (which were using at that time 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.

In photography, angle of view (AOV) 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''.
It is important to distinguish the angle of view from the ...
equivalent to 24–120 mm on a full frame camera.
Advantages
Compared to a standard DSLR the Sony DSC-R1 had 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. The back focal length
The focal length of an Optics, optical system is a measure of how strongly the system converges or diverges light; it is the Multiplicative inverse, inverse of the system's optical power. A positive focal length indicates that a system Converge ...
of the DSC-R1 in wide-angle mode is 2.1 millimeters, which is much smaller than the wide angle back focal length found typically in DSLRs (up to 30 millimeters and more)[Sony DSC-R1 review by ''Luminous Landscape'']

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 rate
Frame rate, most commonly expressed in frame/s, or FPS, is typically the frequency (rate) at which consecutive images (Film frame, frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and moti ...
