Sony Cyber-shot RX100 Digital Camera Review$649.99
The RX100's dynamic range maxes out at 6.55 stops at ISO 80, which is great for a point-and-shoot but poor compared to some SLRs. We're not sure whether to be impressed by the score versus other compacts, or amazed that a comparison to SLRs is even relevant. But either way, 6 and a half stops is the best you're going to get.
By ISO 400 performance drops off to 4.41 stops, but then jumps up again at ISO 800. This is because our test is based on signal-to-noise ratio and, remember, the RX100's noise reduction becomes far more aggressive at this sensitivity. Dynamic range bottoms out at 3.33 stops at ISO 6400. More on how we test dynamic range.
