Everyone is raving about it, but just what makes the Leica Q so good? Richard Sibley puts the premium compact to the test
The Leica Q uses a 24.2-million-pixel full frame sensor, which is most likely a Sony model. Leica has already stated that it’s not the same sensor as that used in the Leica M (which has a bespoke sensor). As can be seen in the tests here, the Leica Q performs just as you would expect it to. It handles noise well until fairly high sensitivities, and the dynamic range is good, without setting any records. As for the resolution, the camera again performs about on par for a sensor of this specification.
Overall, the Leica Q produces good images throughout ISO 100-6,400, which is the working range most photographers will operate in regularly. However, as discussed elsewhere in this test, while the sensor may be seemingly standard, the Leica Q’s real strength lies in its handling, EVF and autofocus.
The Leica Q resolves around 3,600l/ph at ISO 100 in our resolution tests. This level of detail is about what you would expect from a camera with a 24-million-pixel sensor. As can be seen in the resolution chart swatches above, there is some coloured moiré patterning visible that softens detail, but generally the result is good. As the sensitivity rises, the resolution holds up well, still reaching 3,200l/ph at ISO 3,200. Although noise is visible, even ISO 50,000 reaches a respectable 2,600l/ph.
