Panasonic G 42.5 mm f/1.7 ASPH. POWER O.I.S.

6. Distortion

The Olympus M.Zuiko Digital 45 mm f/1.8 had pincushion distortion on a level of 0.7% no matter whether you used JPEG or RAW files in your measurements. In the case of the Panasonic Leica DG Nocticron 42.5 mm f/1.2 Asph. P.O.I.S. we got results ranging from −0.05% to −0.09% so that aberration was practically zero.

What’s interesting, the Panasonic 1.7/42.5 compares not so badly here. When it comes to RAW files, developed by independent software you get barrel distortion of −1.09%. The software of the camera considers that level to be so high that it switches the correction on and for JPEG files the aberration decreases to −0.25%.

As you see there are no reasons to complain seriously but still you can be a tad fussy. A lens with an angle of view of 20-30 degrees shouldn’t have any distortion whatsoever. An absolute value of geometric deformations higher than 1% is already visible on photos and the Panasonic, unfortunately, exceeds that value while its direct rivals don’t.
