Sony NEX-7 High ISO Noise Reduction

The Sony NEX-7 offers three high ISO noise reduction settings: Low, Normal and High, with Normal being the default. The NEX-7 user manual does not say at what ISO noise reduction kicks in, so we've included crops starting from the base ISO of 100.

See for yourself how the three levels of noise reduction works under daylight-balanced lighting. Click on any of the crops below to see the corresponding full-sized image.

It's a little difficult to tell from these crops, but it appears that the NEX-7 already applies "High ISO Noise Reduction" at the base ISO, as there are subtle differences in fine detail between the settings already at ISO 100. It starts to become more obvious at ISO 800 and above.
