The black LUMIX G 20mm f/1.7 II ASPH. Lens from Panasonic is an extremely compact, pancake-style prime lens in the Micro Four Thirds system. It is compatible with Panasonic LUMIX G digital cameras. The lens has a 35mm equivalent focal length of 40mm and a fast f/1.7 maximum aperture that offers great low-light performance. The 7-blade rounded aperture produces pleasing bokeh in the out-of-focus regions of images.

Two aspherical elements minimize both distortion and chromatic aberration. The lens supports the Contrast AF system for high precision auto focusing. Multi-coated elements minimize ghosting and flare to further enhance image quality, and minimum focusing distance is 7.87". The 20mm f/1.7 II features a durable metal mount and body, as well as a 46mm filter diameter.

    I got this lens because I was tired of using my old Canon 50mm 1.8 lens and micro four-thirds adapter for my GH4 and needed a compatible lens that would let me adjust my aperture since I was unable to do so with my adapter for my GH4. I must say though, this lens is definitely more than worth getting! What sold me was the speed having an aperture of 1.7 which is slightly faster than my Canon at 1.8 and what makes me love this lens even more is the auto-focus feature that it has. I normally do video work with my camera but I found myself taking more and more pictures once I purchased this lens. It produces great bokeh wide open all while still remaining pretty sharp. I'd recommend this lens to any videographer/photographer who needs a "go to" lens for all of their projects and even professionals who are looking to add a 20mm to their arsenal of glass.

    This is a great lens for indoor photography. Nice small lens, good field of view, excellent construction and image quality is sharp. Unfortunately this lens focuses very slow. The Olympus Zuiko lenses all have blazing fast and silent focus. Not so with Panasonic. Something about the design, it hunt for focus with every shot. Even if you focus and lock in on the subject. If you refocus again it will bring it out of focus and lock in again. This is not a good lens if there is a lot of action as could occur with many indoor event photography. It is usable, but the 17mm Zuiko is probably a much better lens. I may sell this one to get that.

        Comments about LUMIX G 20mm f/1.7 II ASPH. Lens (Black):

        I bought this lens to use on my GX7 along with the 14-140mm zoom. The two strong advantages over the zoom for me are its weight and light gathering. Between its lighter weight and shorter length, I hardly feel it around my neck or shoulder. It also will slip easily into a coat pocket. At f/1.7 its almost 3 stops faster than the zoom. The difference is being able to shoot at ISO400 instead of 3200. At 400, I can make a beautiful 16x20 print. At 3200 I just can't clean up the noise.

        There are many reviews that talk about the sharpness of this lens and I have found that to be true in low light. But in good bright light, outdoors during the day, I frankly see very little difference in sharpness between it and the zoom. Actually there is very little difference in sharpness between these two lens and the 14-43mm kit lens that came on the GX7. It could be that the GX7 simply can't take advantage of the resolution of the 20mm f/1.7. That said, if you have a GX7 buy it for low light, not for greater resolution.

              The Lumix 20mm f/1.7 is a sharp yet tiny lens that I use as my primary lens with an Olympus OM-D E-M10. The lens support Olympus's S-AF/MF, where turning the lumix's focus ring will override the camera's autofocus. The focusing is smooth and easy on both autofocus and manual focus mode. I chose this primarily because of photozone.de's fantastic review, and the lens certainly lives up to the hype. The E-M10 + Lumix 20mm combo makes for a very compact system good for street or nighttime photography.

                  I was drawn to this lens mainly because of the fast aperture and the small size. I wanted a lens that I could keep on the body while in my messenger bag, so that I could pull it out and take shots quickly. The kit 14-42mm made it too big for my bag.The image quality is great. Good sharpness and color saturation. The only downside is that the AF is noticeably slow. I only have the kit 14-42mm to compare it to.The Olympus 17mm f1.8 was the only other lens I considered, but I went with the Panasonic mainly for it's slightly smaller size.

                    As others have noted, the autofocus is very slow for stills, at least on Olympus bodies. I had on an EM5 but returned for the Olympus 25mm 1.8.

                          Comments about LUMIX G 20mm f/1.7 II ASPH. Lens (Black):

                          I bought this lens as one of my start out lenses for my Panasonic GH4. For the price, I found this lens to be a perfect fast prime lens to start out with until I have the money to buy more expensive lenses. It is unbelievably tiny, very fast, and a solid focal length.

                            Connected to the GX7, this is fantastic street camera, fast and bright. Great in low light. I am new to the 4/3 format and loving the compact size of the pancake lenses.

                              This lens is light and quite bright. However, it is a tiny bit soft in the corners for my taste. Compared with Four-Third lenses 14-54 and 50mm fixed, this lens is somewhat less sharp in the corners. It is quite sharp in the center, even full open. So it is a great lens for portraiture, but not quite for low-light landscape photography.

                                I use the lens for video with GH4, and I would not mind having the option of image stabilization. Since it is functionally 40mm (2x crop on MFT)it is very useful everyday lens. Very light and small, and you can get very nice shallow depth of field at f 1.7

                                      I bought this lens to use on my omd em-5, specifically for travelling/tourism, replacing my 12-50mm kit lens.
                                      This lens is sharp and compresses well. I used mostly primes back with my D-SLRs and am happy to be back at it with this lens/body combo.

                                      not 5 stars due to it's slightly slow auto-focus. I found a few situations where it hunted a bit and is not too quick in it's search.

                                      Optically, this lens is okay, but not really much different than other m43 prime lens with a similar focal length. However, this lens is very small (not that the others are large).

                                      By current standards, the autofocus on this lens is extremely slow, not unlike a macro lens. If you can live with slow AF this lens is okay. This lens is also noisy during operation.

                                      For general use where focus speed matters, the Olympus 17mm f1.8 and 25mm f1.8 lenses (I own both) are much better lenses.
