In May this year Panasonic announced the first premium, constant maximum aperture zoom for a mirrorless system, the Lumix G X Vario 12-35mm ASPH Power OIS. Now, after months of teasing and showing of prototype models at trade shows and press events, it's come out with a telephoto companion, the Lumix G X Vario 35-100mm F2.8 OIS. Clearly both lenses are designed to complement the company's new flagship camera, the Lumix DMC-GH3, and feature a matching dust- and splash-proof design.

The 35-100mm is impressively compact in size, and significantly lighter and more compact than notionally-similar 50-150mm F2.8 lenses for APS-C SLRs, let alone 70-200mm F2.8s for full frame. However this comes with a trade-off in terms of its ability to isolate subjects by blurring the background - in this respect it'll give similar results to an F3.5 lens on APS-C, or an F5.6 lens on full frame.

Naturally the lens is designed with movie shooting in mind, with a linear stepper motor for near-silent autofocus, and Panasonic's video-optimised 'Power OIS' stabilization system. The complex 18 element / 13 group optical system features elements crafted from Ultra Extra-Low Dispersion (UED) and Extra-Low Dispersion (ED) glass, and uses Panasonic's Nano Surface Coating to minimize internal reflections and flare. The diaphragm uses 7 rounded blades to give a circular aperture for attractive rendition of out-of-focus backgrounds. On paper this all adds up to a tempting specification.

Being a Micro Four Thirds lens, the 35-100mm will work on Olympus cameras just as well as Panasonic's Lumix G models, and it looks like particularly interesting match to the Olympus OM-D E-M5 - one of our favourite cameras of the past year. Of course it's also likely to appeal to users of Panasonic's enthusiast bodies, such as the DMC-G5 and GX1.
