Size and design compared...
Olympus XZ-1 and Canon PowerShot S100
 |
| Compared to the conventional compact-style enthusiast cameras, the RX100 fits in pretty well, despite having a sensor two-and-two-thirds times larger. |
 |
| From the top it is clear that the RX100 is a good deal less bulky than the Olympus XZ-1 and not too much thicker than the Canon PowerShot S100, easily fitting inside a shirt pocket. Impressive given that it features a much larger sensor than either of these cameras. |
Fujifilm X10 and Canon PowerShot G1 X
 |
| The RX100's 1"-type sensor is a good deal larger than that used in the Fujifilm X10 (left) but smaller than the near-APS-C sensor that Canon uses in the PowerShot G1 X. Despite falling in the middle of this trio in terms of sensor size, though, the RX100 is comfortably the smallest of the three. |
 |
| As you can see from the top view, the Sony has achieved such a small body in part by omitting both a hotshoe and optical viewfinder. The RX100's fixed LCD screen and lack of a hand grip has also kept keep the body nice and slim. |
