The German reviewers of Digitalkamera (Click here for the translation) tested the new 12-35mm X lens. They say that they never had such a small f/2.8 zoom in their own hands. The build quality is top of the notch. It has a violet color because Panasonic decided to mark preproduction lenses in that way. The Autofocus is “rasend schnell” which means it’s super fast. They sharpness test shows that center and border resolution are practically always on a high level at any aperture. Vignetting is only slightly visible at f/2.8 aperture and almost negligible distortion. Overall a superb lens!
I am now wondering how Olympus will respond to that lens. Will they offer a faster zoom? That is something Olympus can do and no other company managed to do with the 14-35mm f/2.0 (here on eBay) and the 35-100mm f/2.0 (here on eBay) Zuiko lenses….or at least I don’t know of any other fats zoom like these!
