Olympus M.Zuiko Digital ED 12-50mm EZ LensOlympus M.Zuiko Digital ED 12-50mm 1:3.5-6.3 EZ

A brand new splash and dust proof, equivalent 24-100mm power zoom lens from Olympus for the Micro 4/3s system. Targeted at both the videographer and photographers, the light (211g) ED 12-50mm features a fresh variable-speed, ultra-smooth, stealth silent electromagnetic zoom device and delivers "super fast" auto focusing.

The optical layout is comprised of 10 elements formulated in 9 groups, one of which is an extra-low dispersion (ED) lens, 1high refractive index (HR) lens, 1 dual super aspherical (DSA) lens plus a pair of aspherical lens elements. It delivers as much as 0.36x magnification allowing users to fill their frames with subject that measure as little as 48mmx36mm, the 12-50 EZ also pinch hits like a quasi-macro. The lens will sell alone with a $499.99 price tag, and also with the latest PEN cameras: which are the E-PM1, the E-PL3, plus the PEN E-P3 flagship in a kit .

It provide multi-speed zooming power plus the option of a manual zoom. It also features an button for AF hold (labeled L-Fn) that puts AF on hold to circumvent re-focusing on an incorrect object. It is also the first Micro 4/3s lens to encompass the same sealing level as the high-end SHG DSLR lenses

A lens that appears lost. So-so-Macro, internal power-zoom which is weather sealed, although slow. Seems to be another  daytime at the beach lens.

I'd like to see them stay with this 12-50 focal length, although trade off the other attributes for a constant f/2.8 aperture. Olympus already builds a 12-60 and it seems to be one of the better zoom lenses available for the 4/3. So why don't they just port it over to a micro 4/3 mount? But instead they've made a brand new 12-60mm lens that attempts to be all things, but will probably end up doing nothing very well. Dec 16, 2011 ✓
