I have had the Leica Q since Monday - a few observations
- the sensor is fantastic, great latitude, very low noise at base ISO compared to the Leica 240, fantastic colour and easy to post process, very easy to convert to B&W, can\'t wait for it to be used in future Leica cameras
- the lens is very sharp and the issue with corners is exaggerated. Fantastic performance closeup and at infinity even wide open. Distortion can be an issue though particularly for architecture even after the automatic distortion corrections have been applied in the DNG file. I am not sure if Lightroom will eventually have a dedicated profile but I have found that any residual distortion can be corrected if you apply the Leica Elmarit ASPH profile and dial down distortion correction to 80%. I compared infinity performance against my Leica M240 with an Elmarit 28/2.8 ASPH with both lenses set to f5.6 and performance is identical. The Leica M240 seems to have a tiny bit more micro-contrast however it does result in false colour which the Leica Q is handling a lot better (this is not moire)
ergonomics - the camera is perfect for street shooting either using manual or autofocus - the viefinder and LCD are bright and clear, it does need the grip though which is wonderful if used with a wrist strap
