Panasonic announces 12-35mm (24-70mm) f/2.8 for Lumix Micro Four Third cameras
Panasonic has announced a new addition to their micro four thirds lens range in the form a new 14-35mm f/2.8 (formally called the LUMIX G X VARIO 12-35mm / F2.8 ASPH. / POWER O.I.S. (H-HS12035)). The lens has an equivalent angle of view to that of 24-70mm f/2.8 on a 35mm camera. The new zoom lens is weather-sealed and boast both ED glass, IF (internal focusing) and the company's Power-OIS system (optical image stabilizer). Although aimed at enthusiasts the lens is compact and portable. Panasonic has reduced the weight to a low 305g and just 73.8mm in length thanks to the use of four aspheres in the optical construction. There is no word yet on price or availability.
This lens promises very high imaging performance (and resolving power), note that Panasonic has measured at 20 and 40 lp/mm, as opposed to the more usual 20 and 30 lp/mm. The topmost (blue) lines at 20 lp/mm most closely correlate to lens contrast, whereas the lower (green) lines at 40 lp/mm are indicative of the resolving power of the lens. It will be an interesting lens to test; the edges appear to drop away slightly at the longer end, however the MTF only shows maximum aperture.
