Introduction | Panasonic LUMIX G X Vario 12-35mm f2.8 ASPH. Power O.I.S lens performance | Panasonic LUMIX G X Vario 12-35mm f2.8 ASPH. Power O.I.S versus competition | Conclusion

01

The first thing to say about the Panasonic Lumix G X Vario 12-35mm f2.8 ASPH Power O.I.S is that it is the highest scoring Micro 4:3 zoom lens that DxOMark has tested. With an overall score of 17 it beats any other zoom lens by a wide margin and scores reasonably against some very good fixed lenses too.

02

The scores for Micro 4:3 are not very high, the best score for any lens being 23 (compared to scores of up to 40 for full frame 35mm). Taking a closer look at the individual scores does raise some concerns: Chromatic Aberration at 11µm is not very good; there are many lenses better than this, though these are fixed focal lengths. Distortion is also problematic, not taken as a whole but specifically when looking at the wide-angle setting where it is very noticeable. Vignetting is quite well controlled and sharpness at 9 P-Mpix is higher than most in this sector, however it does fall off as the aperture is stopped down (see Comparison).

Raw measurement shows a high level of distortion for shorter focal lengths

On the plus side the score for Vignetting is pretty good
