The Sony DSC-R1 is a bridge digital camera announced by Sony in 2005 (and discontinued in 2006, the year it won a PC World Innovations Award). It features a 10.3 megapixel APS-C CMOS sensor (21.5 × 14.4 mm), a size typically used in DSLRs and almost never used in bridge cameras (which usually use 2/3" (= 6.6 × 8.8mm) or 1/1.8" (= 5.3 × 7.1mm)). This is the first time such a large sensor has been incorporated into a bridge camera. Besides the APS-C sensor, R1 also features an excellent lens for its class, 24-120mm Carl Zeiss® Vario-Sonnar® T*, to produce above average image quality.
Advantages edit
Compared to a standard DSLR the Sony R1 has the following advantages:
- live preview which gives information about the image before the picture is taken
- swiveling LCD display which allows shooting in difficult positions
- 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 (this is one of the Achilles heels of SLRs - wide angle shots on a standard SLRs suffer from lack of sharpness in the corners and vignetting)
- the image in the EVF 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.
- during manual focus the image is magnified in the LCD screen or EVF — few DSLRs can do that.
- 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
- fewer movable parts, therefore more reliability
Disadvantages edit
and the following disadvantages:
- no interchangeable lenses: the supplied lens, while being of good quality, only covers the 24–120mm zoom range. A teleconverter (1.7×) and a wide angle converter (0.8×) exist, but they are very bulky.
- no optical viewfinder: while the EVF is relatively good, it does not have sufficient resolution to allow precise manual focus in most situations. Furthermore there is some small time shift, i.e. the image appears with a small delay.
- the Sony R1 has slightly higher noise levels than a standard DSLR.
