Sony Cyber-shot DSC-RX1R lens review: Sharp, but not without some compromise...By Kevin Carter - Tuesday August 27 2013 Lens Review
With an DxOMark Lens score of 37 points the new special edition Sony RX1R scores very highly, and ranks in 7th place overall in our database, achieving a similar score to the Sigma 35mm f/1.4 DG HSM A when mounted on the 24P-Mpix Nikon D600.
As for the all-important Sharpness score it achieves a 20P-Mpix rating, which is one of the highest in our database (given the sensor’s pixel count). It is perhaps not quite as high as it could have been, though it’s likely due to sensor efficiency than the resolving power of the lens. As for other imaging characteristics the Zeiss performs very well although it’s not quite at the same level of the retro-focus Sigma. Chromatic aberration is in double figures but it’s still relatively low, while distortion, on the other hand is a little higher than expected (and noticeable in certain images).
