Panasonic LUMIX G X VARIO 12-32mm F3.5-5.6 ASPH Review
Introduction
The Panasonic LUMIX G X VARIO 12-32mm F3.5-5.6 ASPH is a tiny standard zoom lens for the Micro Four Thirds system. Providing a focal range of 24-64mm in 35mm terms, the 12-35mm lens is both compact and lightweight. It combines 8 elements in 7 groups (3 aspherical lenses, 1 ED lens), and has seven blades which give the aperture a rounded shape. The Panasonic LUMIX G X VARIO 12-32mm F3.5-5.6 ASPH lens is available for £329.99 / $349.95 in the UK and the US, respectively.
Ease of Use
The LUMIX G VARIO 12-32mm F3.5-5.6 ASPH is a tiny and incredibly lightweight collapsible standard zoom lens covering a fairly versatile 35mm equivalent focal range of 24-64mm. When it's collapsed it measures just 2.4cm in length. Zoomed out to the 64mm setting, it then measures 5.5cms. Weight is a mere 70g, thanks to the mostly high-grade plastic construction, but commendably there is a metal lens mount.

In terms of features, the LUMIX G VARIO 12-32mm F3.5-5.6 ASPH has little to offer (apart from its small size, of course). There is no distance scale and no focus limiter, and there is no handy image stabilisation switch for the Power O.I.S system either. Instead O.I.S is enabled through the camera's menu system, usefully offering around 3-stops of compensation.

The LUMIX G VARIO 12-32mm F3.5-5.6 ASPH doesn't come with either a lens pouch or a hood. You can fit 37mm filters to this lens and the filter thread doesn't rotate when focusing.

Focal Range
At the 12mm end of the zoom range the lens has a diagonal angle of view of 84°, equivalent to that of a 24mm lens in a 35mm system.

At the 32mm end the angle of view is 37°, which is the same as that of a 64mm lens on a 35mm full-frame camera.

Focusing
The LUMIX G VARIO 12-32mm F3.5-5.6 ASPH lens offers near silent focusing thanks to the inclusion of a stepping motor. In use, we found the system surprisingly quick on the DMC-GM1 that we tested the lens with. The lens also incorporates an inner focus system, good news for filter users, as it means that it doesn't rotate in use. This combination of silent and quick focusing makes the lens well suited to shooting both stills and video.
Manual focusing is simply not possible, as there is no manual focus ring on the lens, one of the neccessary compromises it seems to make the lens so small.
Chromatic Aberrations
Chromatic aberrations, typically seen as purple or blue fringes along contrasty edges, are not too much of a problem with this lens at either end of the focal range.
Light Fall-off
With the lens set to its maximum aperture, you can see some light fall-off in the corners at both 12mm and 32mm, but nothing too excessive. You will likely only notice this when photographing a subject with large homogeneous surfaces. There is some pretty obvious barrel distortion at 12mm though.

Macro
The LUMIX G VARIO 12-32mm F3.5-5.6 ASPH has a closest focusing distance of 0.20m/0.66ft from 12-20mm and 0.30m/0.98ft from 20-32mm, and a maximum 0.13x magnification rating, so it's no macro lens, although that's not surprising for a standard zoom lens.
Close-up performance
Bokeh
Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. In the LUMIX G VARIO 12-32mm F3.5-5.6 ASPH lens, Panasonic have employed an iris diaphragm with seven rounded blades, which has resulted in quite nice bokeh in our view. We do realise, however, that bokeh evaluation is subjective; so we've included several 100% crops for your perusal.
