Great lens. The extras make it really worthwhile. Very sharp. AF is a little slow/loud, don't let that stop you.

Fringes in harsh light otherwise worth it for the price and size.

Micro four thirds is the best! My favorite lense so far, a must have in the Panasonic system

Feels good AF could be quieter, sounds like an older motor. Optics are good

Great low light lens. Needed a lens to shoot family gatherings indoors and this one is wide enough and great in low light.

This Panasonic lens is perhaps the best performance you can get for the price. There are better primes for m4/3 that does better in low light, but they cost about double as much. Being a pancake lens, this prime is very thin and can make a camera pocketable--depending on the camera model of course. The auto focus motor in this lens is pretty loud. Much more so than the 14-42mm kit lens. The motor noise won't matter when taking pictures, but it becomes annoying when taking video. The motor noise is clearly audible especially during periods of low environmental sounds.

This lens is small, fast and sharp with a nice angle of view. It looks great on the camera and functions perfectly. A very good value. Love it.

I have this lens mounted on an Olympus OMD EM5 MK II. I really like the rendering of this lens in addition to it's small size. I also had the Olympus 25mm but ended up selling it after I got the Panasonic 20mm because for me, the images just had something different compared to the Oly and 20mm is more compact. The lens does make a little weird noise when it focuses but I have gotten used to it.

I have used this lens now about 2 months and it is a very sharp lens. The build quality is good. However, if you are just starting out, and you can afford the olympus 12-40mm lens, I would recommend that one over this lens. Buy the 20mm you will not regret it.

As a landscape painter and photographer I find this lens perfect! Tack sharp, and very compact, and fast for low light!

Bought this for low light (which it does well) and the compact design, I now use it as my main lens for most everything. Good clarity and saturation... makes it hard to use anything else.

This lens has compact format, good sharpness and very good low light performance. The reviews are usually good. This lens was recommended by friends too. I am very happy i bought it.

Couldn't be happier with this purchase. Adorama had a used (but previously loved!) copy of this 20mm f/1.7 for sale on their website. I was about to buy it online, but gave them a call anyway. The sales person I talked to on the phone had another used one available and offered even a better price. He promptly helped me put an order together, and the lens was shipped to me with all the proper packaging so it doesn't get damaged. Great service and price! As for the lens, I couldn't be happier with it. It's compact, bright, fast, and gives decent bokeh too. It's my go-to lens for when I want to take a nice shot in low light situations with my Lumix G5. The one only thing that bugs me a little is the way it focuses sometimes - it does make a fuss with the noise and slightly slow movements. But at least the manual focus offers accurate "focus-by-wire" operations. I would recommend this lens. Just be prepared to pay a decent amount for it though - it seems the price for a new one has actually gone up a bit in the past couple of weeks.

This is an amazing lens, the focus is a bit slower on non native systems like my om-d but its still faster than most Dslr's. Its a beautiful lens, its my go to for street photography. I highly recommend.

This is a great addition to my GH2-14/140 lens package. I seem to end up wanting to take a lot of pictures in low light situations, handheld, so this lens fill the gap. And, the images are really sharp. Really enjoy having it.

This is an amazing glass. It is quite sharp wide open. Great for street photography, portrait and night photography. It is my go to lens for video.

The 20mm f1.7 on the OMD EM5 makes for a nice compact combo. Good quality results and excellent in low light.

Just buy it, you'll love it! Great on my Panasonic GX1, I'm sure it would also be a killer combo on the Olympus OMD as well.

This is the lens people say you HAVE to get and you should question that typically -- but this lens is really too good to pass up. It's sharp wide open, reliable, small and well built with a metal mount. The only downside I can think of is that it is an older design that moves everything to focus and this slows it down over the latest offerings -- but really, it is scarcely an issue in all but the most fast moving circumstances. It's not stabilized in-lens, but on an Olympus body it is stabilized by the IBIS. I have used this lens primarily for street and personal photography and it is something I ALWAYS carry for use with my E-P3 or OM-D E-M5. I think it truly is a "must have" for a slightly wide angle prime or as your traditional 50mm equivalent "normal" lens.

I wanted a fast lens that beats the zooms I have and the 20mm is a good length for me. It is not a fast focus (on the GH1) but I mostly use manual focus anyway. The focus ring is nice and precise, build quality is good. I find the 20mm a really good option for Panasonic primes under 400 at a good focal range (40mm).

This is a must have lens for any m43 kit. Perfect for street, portrait , landscape, and any other use for a somewhat normal focal length lens (at 40mm). Focus is reasonable on my OMD, and image resolution is great wide open, even better stopped down to f4–5.6 or so. A perfect walk around lens, that works quite well in low light. Night shots hand held are possible with this lens - a great prime lens for a m43 kit.

The LUMIX G 20mm/F1.7 ASPH, a compact and lightweight "pancake" lens with outstanding brightness
The LUMIX G 20mm/F1.7 ASPH lens is dramatically compact and lightweight, featuring an outstanding F1.7 brightness which allows consumers to create stunning photos with beautiful, soft focus. Comprised of seven lenses arranged in five groups, the LUMIX G 20mm lens actually uses two aspherical lenses to effectively minimize distortion and achieve super high resolution.
The versatile 20mm focal length (equivalent to 40mm on a 35mm film camera) is suitable for allapplications - from scenery shots to dimly-lit indoor environments. When mounted on LUMIX G Micro System Cameras, the LUMIX G 20mm/F1.7 ASPH lens allows for use of the advanced contrast Auto Focus (AF) system, which includes Panasonic's Face Recognition functions. Both lenses are comprised of seven blades, which produce an attractive and smooth background blur effect when shooting at larger aperture settings. These lenses also feature a highly-reliable metal mount, and use multi-coated lens elements to minimize glare andfurther enhance optical performance.
