For what it is – a very small, sharp, fast lens for an affordable price – it's great. The build-quality is also note-worthy. It's the perfect complement to a G series or Pen camera when you're going for portability.

Aberration; Fringing

Gary Wolstenholme reviews the Panasonic 14mm f/2.5 Lumix G, a lens with a pancake body costing around £290.

Miniature size; Excellent sharpness; Fast AF; Low CA; Good value price

Can be quite prone to flare with a bright light in the frame

Bought this to use with Black Magic POCKET Cinema Camera as a stealth/guerilla/walk around lens. No one even looks twice at me with this, everyone thinks I'm just taking photos.

Nice little lens but CA is an issue. In fairness, I think Lumix cameras can correct for this but I shoot Olympus. The lens is sharp and very compact. Focus is silent. Good enough for the money.

Panasonic's Lumix G 14mm f/2.5II ASPH lens has a lot in its favour, even though the sample we tested was a bit below par, resolution-wise. Small enough to slip into a shirt pocket and fast enough for shooting in dim lighting, it is also inconspicuous and, therefore, ideal for street photography.

At 14mm the lens has a diagonal angle of view of 75°, equivalent to that of a 28mm lens in a 35mm system.

It's a tiny and incredibly lightweight lens but performance is really excellent when it comes to image quality.

Consistently sharp across the frame; Very small and light; Metal mount

Narrow manual focus ring; Pancake design restricts maximum aperture to f/2.5

Mount: Micro Four Thirds | Construction: 6 elements in 5 groups, 7 diaphragm blades | Closest focus distance: 18cm | Filter thread: 46mm | Autofocus: stepping motor | Dimensions: 56 x 21mm, 55g | Tested on: Panasonic GX7 So-called pancake lenses have been around for more than a century and, while...

It's a prime lens, and I love my Panasonic 20mm f 1.7, but this is nothing similar. Focusing is somehow worse (although it's fast and quiet it's shockingly inaccurate) but even worse this lens is incredibly soft. Don't bother.

I bought this to be the main lens attached to my GX7 all the time, in lieu of a front camera cap. I figured it would also serve well as the "just grab it and shoot" kind of lens, where I see a shot and need a camera (with a lens already attached) quickly as possible.
