Panasonic LUMIX G X Vario 12-35mm f2.8 ASPH. Power O.I.S review - Panasonic’s Quality Standard Zoom for Micro 4:3By Ben Boswell - Wednesday March 20 2013 Lens Review
Panasonic Lumix G X Vario 12-35mm f2.8 ASPH Power O.I.S vs. Panasonic G X Vario PZ 14-42mm f3.5-5.6 Asph. Power O.I.S vs. Olympus M.Zuiko Digital ED 12-50 f3.5-6.3
Here are 3 “standard” zoom lenses, each spanning the wide to short telephoto range. Panasonic’s 14-42 goes a little longer but not as wide while the Olympus matches the G X Vario at the wide end and goes even longer. Both of these competitor lenses are much slower and both have variable apertures, but they are also very much cheaper, much less than half the price.
The DxOMark scores for the cheaper lenses are 10 and 10 against the 12-35’s score of 17. The chart would seem to suggest that all of the advantage that the 12-35 has is when it is used wide open, the scores between f5.6 and f22 are much closer together.
The score for Sharpness certainly favors the Lumix G X 12-35, it performs very well wide open at f2.8 where the other lenses cannot compete. At smaller apertures the differences are small.
Panasonic Lumix G X Vario 12-35mm f2.8 ASPH Power O.I.S vs Olympus M Zuiko Digital ED 12mm f2 vs Olympus M Zuiko Digital ED 45mm f1.8
To put things in perspective here are the best scoring 12mm fixed focal length and 45mm, a combination that some people might prefer. The combined price of these two lenses is similar to the Lumix G X 12-35 and their weight together is similar too. The DxO Mark scores are 19 for the 12mm and 20 for the 45 so slightly better.
