Sony Cyber-shot DSC-RX1R lens review: Sharp, but not without some compromise...By Kevin Carter - Tuesday August 27 2013 Lens Review
Comparing the two models side-by-side we can see that removing the OLPF has improved the DxOMark scores somewhat. Bear in mind this is single score is simply a bench-marking exercise and to see how well the lens performs we have published the results here.
Comparing the Sharpness scores directly we can see there’s an increase of 2P-MPix over the RX1, or an increase in acutance of 5% at the maximum aperture. As you might expect, there’s no improvement in the uniformity across the field, but the increase in rendering of fine details is at its most apparent when wide-open. At other aperture settings the acutance varies between 0-5%:
As for the other lens metrics the results are within the error of margin for testing but still likely an accurate reflection of the effects of removing the OLPF.
