The LUMIX G 20mm / F1.7 ASPH., is a compact interchangeable lens based on the Micro Four Thirds System standard. It features a bright maximum aperture of f1.7 allowing a shallow depth of field to separate your subject from the background for even more impressive photographs.
Comprising of 7 elements in 5 groups, the lens system also employs 2 aspherical lenses to minimize both distortion and chromatic aberrations, achieving a high corner to corner resolution.
The versatile focal length of 40mm (35mm camera equivalent) is suitable for a wide variety of occasions from daily snapshots including sceneries like sunsets and dimly lit indoor shots to the deliberately creative shots taking advantage of its beautiful depth of field capability.
When mounted on LUMIX G Micro System Cameras, the LUMIX G 20mm / F1.7 ASPH. allows use of the advanced contrast AF system which includes a Face Recognition function, for more convenient and enjoyable shooting.
Seven blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings. The lens also features a durable metal mount and uses multi-coated lens elements that minimize ghosting and flare to further enhance its optical performance.

I can only comment on the performance of the lens when paired with the Lumix GX1 but it's superb for just about anything at most light levels, indoors or outdoors.
For close up and mid-range 'journalistic' style, point-and-click photography it's a dream (it has no zoom capability as you probably know, so photographs are taken as seen). Really vivid, vibrant, sharp images with lovely bokeh effects are achieved very easily and I take it everywhere whether I'm working or for pleasure. Combined with a good compact system camera it makes a fantastic, professional quality, portable package.
The lens makes a little noise when focusing but nothing off-putting by any means. Build quality seems great for a lens in this price range. If you can get one at a good price, make sure you do (I got mine in the Christmas cashback offer at a steal)
I use it on my Olympus PEN E-P1 and my wife's Panasonic G2; on either camera it transforms the overall size making them both look and feel much smaller. Focus speed is OK, though I must say it seems a bit slower to focus on the G2 than the PEN for some reason - after the last firmware upgrade the PEN has got much snappier in this respect.
In use the 20mm gives a 40mm equivalent on a traditional film SLR (or Full frame DSLR) which isn't quite standard lens length and the extra field of view can lead to distortions if used without care on portrait shots though it's not that wide for landscapes either! Having said that having a prime lens makes you think more about your shots and you'll get picture you just wouldn't with a lazy old zoom.
One of the top benefits of this lens is the super wide (for M43!) 1.7 aperture. This Makes it good for low light photography and in some conditions enables you to get a nice blurry background. This is especially nice on the PEN as it has in camera stabilisation, there is no OIS on the Lumix 20mm. Chromatic aberrations isn't an issue on the PEN and the G2 removes any it finds it automatically, so zoom users that get annoyed with purple fringing will be happy too.
So, this is a compact lens that is pin-sharp and great for low-light pics and makes some M43 cameras almost pocketable. Five stars without question.
However, the Panasonic lens is lovely - simple, fast, small, great quality. Works a treat indoors, I have yet to use my Olympus flash for real. I actually like having the fixed focal length... My preferred lens of the two, even though of course the Olympus kit zoom lens is more versatile with the 14mm-42mm zoom.
I used to have 50mm as my favourite focal length, but I'm really enjoying that extra width of this 40mm lens (talking 35mm camera equivalent here). For portraits, though, it starts to be a bit too wide if you're aiming for close-ups, as they'll look a bit unnatural -but it's ok from head and shoulders portrait length on.
The F1.7 aperture is great for lower light conditions or if wanting to separate the subject from the rest of the image by taking advantage of the so reduced depth of field. The downside is that it might often be too little depth of field, so for example in a portrait which is at a slight angle, you'd get only one eye in focus (not a problem if you're shooting a pirate or commoner wearing an eyepatch or the London 2012 Olympic mascot).
