Sony Cyber-shot RX100 Digital Camera Review$649.99
The RX100 captures gorgeous, high bit rate videos that are some of the best we've seen from a still camera. Motion is handled particularly well thanks to the 60p frame rate. In fact, other than a little bit of frequency interference, video footage gave us almost nothing to complain about. More on how CamcorderInfo tests motion.
Under studio illumination, the RX100 produces sharp video footage. The sensor is capable of resolving 550 lw/ph of image detail horizontally and 600 lw/ph vertically. More on how CamcorderInfo tests video sharpness.
In low light, video performance is very much the same. However, as you'll soon read, this has more to do with the sensor's excellent sensitivity than its performance under difficult light. Anyway, in our 60 lux test, the sensor achieved 500 lw/ph horizontally and 600 lw/ph vertically.
Low Light Sensitivity
The RX100 has exceptional low light sensitivity. In order to gather 50 IRE of image data, the sensor requires only 3 lux of ambient light. This must be partly the result of the camera's huge aperture, and puts performance on par with the best prosumer camcorders.
This of course explains the strong low light sharpness score 60 lux is barely a challenge for this camera.
