Lab tests

We use Imatest and DxO Analyzer hardware and software to test cameras for their colour accuracy (colour error) signal to noise ratio (the amount of noise in the images) and dynamic range (their ability to capture detail in very bright and dark areas). We also pick three rival cameras to test them against. 

Colour error


Signal to noise ratio

The EOS 800D produces slightly less noise than the EOS 750D and a lot less than the Nikon D5600. But Fujifilm’s X-T20 produces a much better result across the ISO range.

Dynamic range

The EOS 800D does especially well here. Its JPEG files might be prone to highlight clipping, but we test the raw files (converted to TIFFs), which reveal its true capabilities.
