As powerful as they've become, Mirrorless camera systems can't match the versatility of a full-size DSLR. One key component we haven't seen is a constant-aperture lens, offering a consistent large aperture size throughout the zoom range. That changed today. Panasonic's new Lumix G X Vario 12-35mm optic packs one incredible advantage over its compact competitors -- a constant f/2.8 aperture. Because of the Micro Four Thirds system's 2x multiplication factor, this 12-35mm lens covers the same zoom range of 24-70mm glass on a full-frame camera, in a significantly smaller package. The optic consists of 14 elements in nine groups, and includes UED and UHR lenses to increase image quality and minimize distortion, along with built-in image stabilization and Panasonic's Nano Surface Coating to reduce ghosting and lens flare. It's also splash- and dust-resistant, and features a metal mount on the rear. Panasonic has yet to release pricing in the US, but the European price tag has been estimated at €1,100 (about $1,400) -- by comparison, Canon's equivalent optic (from a specification perspective) will run you $1,600. For its part, the 12-35mm MFT lens is expected to hit stores in August. Full PR is just past the break.
