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
9 December 2012
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.
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.
Summary: If you own a micro 4/3 camera, you need to own the Panasonic 20mm f1.7 lens, stat. I could end my review here, because, well, nothing more needs to be said. If you need convincing, let me expound. There is no other more versatile lens in the m4/3rds ecosystem which provides anywhere near the cost/performance value. Chromatic aberration is almost non-existent, even at full aperture (f1.7). If there's any vignetting, I haven't seen it.
Summary: This lens will convert any good micro 4/3 (like my Panasonic GH2) in a camera very capable to compete with the cool Fujifilm X100. Of course the latter has a bigger sensor (APS-C) that allows a better performance in low light, but is very limited because of its fixed lens (and no, your legs are not always the substitute of a zoom; try to use them to photograph a distant plane or bird, or to get a far away mountain closer in a close-up).
Summary: I recently purchased a Panasonic Lumix DMC-GH2 16.05 MP Live MOS Interchangeable Lens Camera with 3-Inch Free-Angle Touch Screen LCD (Black Body Only) . The purchase was largely inspired by a desire for a smaller interchangeable lens camera for travel purposes. Since size was a major consideration I knew I wanted a fast, "pancake" prime to go with it. I'm so glad I decided on this lens.
