Generally, some of the advantages of the Sony DSC-R1 compared to entry-level DSLR competitors include: it has a CMOS-family sensor (CMOS vs CCD) and has more storage slots (2 vs 1).
However, on average it doesn't record movies (none vs 1080p @ 30fps), has a much smaller screen (2" vs 3"), has a much lower resolution screen (134k dots vs 921k dots), doesn't have image stabilization (none vs sensor shift) and takes much lower resolution photos (10.1 MP vs 20.1 MP).
Generally, some of the advantages of the Sony DSC-R1 compared to mirrorless interchangeable-lens competitors include: it has higher quality type of viewfinder (digital vs none), has more storage slots (2 vs 1) and has a built-in flash.
However, on average it doesn't record movies (none vs 1080p @ 60fps), has a much smaller screen (2" vs 3"), has a much lower resolution screen (134k dots vs 1,040k dots), doesn't have image stabilization (none vs sensor shift) and takes significantly lower resolution photos (10.1 MP vs 24 MP).
Generally, some of the advantages of the Sony DSC-R1 compared to super zoom competitors include: it has a slightly wider wide angle lens (24 mm vs 36 mm), has a CMOS-family sensor (CMOS vs CCD), has a much larger sensor (sigma x3 21.5x14.4mm vs 1/2.3" 6.17x4.55mm), has more storage slots (2 vs 1) and supports an external flash.
However, on average it has a much smaller screen (2" vs 3"), has a much lower resolution screen (134k dots vs 921k dots), is significantly larger (large (139×168×97 mm) vs professional size (125×84×102 mm)), doesn't have image stabilization (none vs lens) and takes slightly lower resolution photos (10.1 MP vs 20 MP).
Generally, some of the advantages of the Sony DSC-R1 compared to pro digicam competitors include: it has a much larger sensor (sigma x3 21.5x14.4mm vs 2/3" 8.8x6.6mm), has a significantly wider wide angle lens (24 mm vs 28 mm), takes slightly higher resolution photos (10.1 MP vs 4.9 MP), has a CMOS-family sensor (CMOS vs CCD) and is newer (september 2005 vs august 2003).
However, on average it has a significantly narrower aperture (f/2.8 vs f/2), is significantly larger (large (139×168×97 mm) vs professional size (135×82×103 mm)), is slightly heavier (995 g vs 724 g) and has a slower max shutter speed (1/2000 of a second vs 1/4000 of a second).
Generally, some of the advantages of the Sony DSC-R1 compared to pro DSLR competitors include: it has more storage slots (2 vs 1).
However, on average it doesn't record movies (none vs 1080p @ 30fps), has a much smaller screen (2" vs 3.2"), has a much lower resolution screen (134k dots vs 1,040k dots), takes much lower resolution photos (10.1 MP vs 24.2 MP) and doesn't shoot as fast continuously (3 fps vs 5.5 fps).
