Summary: This 20mm f1/7 lens is what I reach for more than anything else; I've had more stellar pictures with this lens and it's so fun to use. The thin pancake profile is small enough to fit into a larger pocket (think jacket pocket rather than jean pocket) when paired with a GF1/GX1. The colors are fantastic, the bokeh is good... but where this really shines is the low light performance, the stellar depth of field and sharp images.
Summary: Everyone raves about this lens, and they're all absolutely right. I wasn't totally convinced until I used it in a museum. It was pretty dark, but with the f/1.7 it was easy to get the exposure I needed to take awesome pictures. It's super clear and it's also compact. This is the default lens on my Lumix GX1 because it's compact and probably the best prime lens in the m4/3s market.
Best micro four thirds pancake lens for photography but not videography

Summary: I bought this lens for its compactness and low light performance. This prime lens has fantastic bokeh. There are some things that can be improved. This lens badly needs an upgraded silent and faster focusing motor. When recording video, the motor can be heard when focusing. That is the main reason I upgraded to the Panasonic Leica 25mm f1.4.
Summary: I read every review on this item before I ordered what for me was a pretty expensive camera accessory. I'm talking to folks who bought the Panasonic G3 as a step-up from a point and shoot: Even if you're still shooting often in auto mode (and just learning the intracacies of f-stops, shutter speed and the rest), this is a great addition to your kit.
Summary: I'm using this with the Olympus OM-D E-M5 16MP Live MOS Interchangeable Lens Camera with 3.0-Inch Tilting OLED Touchscreen (Silver) and I love it. I originally bought the OM-D with the Olympus M.Zuiko 17mm f/2.8 Lens but was disappointed with the contrast in the 17mm lens, and I didn't initially know that Panasonic made a similar Micro 4/3 lens that's even better! For just a little more money this one is a no-brainer, because the lens is so much better.
Summary: I'll admit it: I'm a Canon "L" lens snob... I don't settle for less and I normally use a 7D with only "L" lenses... but I've grown weary lugging my gear everywhere and wanted a smaller camera so I could carry one with me at all times. Enter the Oly E-PM1... got it refurbished for a reasonable price so I thought I would try it out. In addition to my little camera, I also bought the Panny 20mm f/1.7.
Summary: I rarely write reviews, and this lens already has plenty, but I just had to add my voice to the chorus: Buy this lens. I know, "it's not about the equipment," but if you're looking to move on from the kit lens that came with your camera, this is the one to get.
I'm not a photography expert, but I really like the lens

Summary: I read the reviews on this lens here and on DP Review. People with knowledge rave about the performance of the lens at this price. I've moved up from a point-and-shoot, so hey, anything's going to look better to me. I am really happy with this lens on my GF3. It focuses quickly and I can take pictures of my house rabbits without a flash under most conditions. The rabbits have the albino coloration with pink eyes.
Summary: I originally purchased this lens to use with my EPL-1 camera and I enjoyed great results with it. I now use it with my Lumix GH2, which is probably the best M4/3 camera currently available. This is a PRIME lens, which means that it has a fixed focal length (i.e. not a zoom lens). The benefits of a prime lens in general are that they tend to be smaller, faster and sharper. The 20mm Lumix lens has a great character, and is able to capture beautiful photographs.
Summary: I have limited experience as a photographer--more like a "camera operator," but I have years of experience in post processing of school portraits. I simply would like echo what a few reviewers have mentioned: the Lumix G 20mm f/1.7 is not ideal for portraiture. That is, anything tighter than a bust crop. Shots taken within 2 feet of the subject could result in facial distortion, which becomes more significant as you get closer.
