I am a hobbyist, and a big fan of prime lenses with wide apertures, because I enjoy using a narrow DOF for my artistic experiments. I became interested in this lens based on reviews and example photos - but it didn't seem to be in stock anywhere, which may account for it's cult-like following.

I finally found it in stock at B&H and purchased one immediately. I have used it exclusively ever since, on my Olympus E-PL1 - even though I have a variety of other lenses and cameras. The pancake form factor and the incredible performance make it a joy to use...Now I am not a pro and the micro 4/3 format is still very new...but I absolutely love this lens and if I had to make a choice I'd keep this one and sell all the rest.

It has great performance in low light, and can really get that closeup, narrow DOF that I admire. Plus, the form factor makes it unobtrusive in public - almost as small as a compact camera but with stunning output. I am glad I believed the hype about this lens - I'm really happy with it.

You hardly ever see overwhelming consensus about any product. But it's clear from consumer reviews, scientific reviews, professional reviews, and online forums that everybody loves the Panasonic 20mm f/1.7. It seems to be the desert island lens of the Micro Four Thirds system.

And that's why I bought it. I had the Panasonic 14mm, which I've always loved, and wanted a faster walk-around lens with a little narrower field of view. It seemed like a no-brainer, since the 20mm is reputed to be the must-have lens.

It is pretty nice, optically. Sharp images throughout the frame, a good low-light performer, a useful normal 40mm-equivalent field of view, decent control over depth-of-field. But, there were three factors that kept me from falling in love with the 20mm. Those are:

(1) Autofocus performance is lackluster. This is a common criticism of the Panasonic 20mm, and I knew about it going in. But it really started to bother me, given the autofocus speed of other lenses, particularly the 14mm. I'd miss shots of my kids, shots that the 14mm could always nail.

It started to feel like a huge burden to have the 20mm mounted to my camera. In good light, the AF was fairly fast, but in low light--the kind of light you're buying the f/1.7 for in the first place--it chokes. It hunts. Sometimes it gives up and just goes back and forth forever.

This is, apparently, inherent to the focusing mechanism, which transports the entire lens assembly back and forth, so it's not something that can be corrected with a different body or a firmware update. That's my understanding, anyway.

(2) High-ISO banding. This is discussed endlessly on forums. What causes it? Does it even exist? Is it the fault of the camera or the lens? Well, it definitely exists on Olympus cameras with the new sensor (those being OM-D, E-PL5, and E-PM2). At ISO 1600 and up, in dark parts of the frame, horizontal bands of alternating light and dark regions make photos entirely unusable. It's not something that you need to pixel-peep for, it's out there like the stripes on Old Glory.

This won't be a problem with other cameras, so if you've got a Panasonic body, or an older PEN, no worries. Olympus has acknowledged the issue, but I couldn't hold my breath for a fix. It might be the camera, and it might be the lens, and it might be some weird confluence of factors that make it nobody's fault at all.

If you have one of these Olympus bodies, you know that ISO 1600 is a perfectly usable ISO, so it's a disappointing situation. This issue by itself doesn't disqualify the 20mm as a good lens, but it does sort of move it out of the "must have" category, because you'll need to work around this.

(3) It's bad at video. Probably related to point 1, but a barrier by itself, the 20mm autofocus hunts like crazy when used for video. Video tends to renew its focus quite often because subjects move around, and the 20mm just can't keep up. Perhaps AF data comes out of the camera faster than the 20mm's motor can move the lens, and the lens and camera kind of miss each other. I don't know. And while all this hunting is going on, it's making a noise loud enough to be noticed in your audio track. I don't shoot loads of video, but it's nice to be able to do it occasionally. The 20mm is simply not a video lens.

So there it is, probably the only negative review of the Pansonic 20mm that you'll ever read. I'm vastly outnumbered, so I'm sure you, dear reader, will think the lens is terrific. And in many ways, it is. It's possible that its time has passed without anything obviously replacing it.

    Comments about Panasonic Lumix 20mm f/1.7 Aspheric G- Series Lens:

    I use this bright and compact lens any time I'm trying to get a shot indoors, inside a restaurant, when a subject is moving erratically, and anytime I need to blur the background. When mounted to my Panasonic GF2 the combo is small enough to stay extremely portable while offering beautiful pictures in conditions point-and-shooters could only dream of. Fast auto-focus and smooth manual focus. No issues after more than a year of use.

            Small, light and razor sharp. Focus is a little slow (relative to other lenses, even my kit zoom), but that's not a problem for me - not enough to drop a rating star. Nice to have a fast lens as well - images are great even wide open. I see no reason to pay $ more for the version II. So it has a metal "finish." The mounts are the same as are the internals.I use it on my Olympus E-PL5 and I'm grateful that 4/3rds is universal!

            Nice lens with fast aperture. I use it with a hacked Lumix GH2 and the video image is awesome. The cons, the autofocus is noisy for audio capture even with my Zomm H1 in DIY suspension.

                  Comments about Panasonic Lumix 20mm f/1.7 Aspheric G- Series Lens:

                  I've only had this lens a short while but I absolutely love its performance in low light. I am a professional music producer/audio engineer and needed a fast lens to capture images in dim to non-existant studio light. The majority of my artists like to record with the lights dimmed considerably and sometimes with only candles lit. So capturing them during a session from the control room has been difficult. Not anymore. I was using the 14mm 2.5 pancake as well as a Canon 50mm 1.8 (fantastic plastic) and this thing just flat out kills in low light! In all fairness, the Canon is great, too. But I needed a wider lens for capturing whole ensembles and bands. Image quality is great and the 1.7 allows me to capture expressive shots in an environment that's difficult for slower lenses and where a flash is out of the question.

                  Only 4 stars because for video, there is too much hunting while trying to focus. In and out... in and out.. in and out. Lame. This is where the 14mm pancake excels over the 20mm. In fact, using the 20mm for video has been a frustrating mess... to the point where I have nothing but out of focus moments captured amidst a few frames of usable material. Totally weak.

                    Instead of me raving about this lens like everyone else has, look at the footage I shot. I knew this film would be almost all night shots. I also knew I was going to be shooting inside the car at night. I need something wide and fast. I got both with this lens. I was not planning on using it as much as I did, but it ended up being my go to lens during the whole shoot.

                      I purchased this lens to replace the kit lens that came with my Olympus Pen E-PL1. I'm fairly new to the world of photography beyond point and shoot, so my photography skills are fairly rudimentary, but even I couldn't screw up the pictures taken with this lens. They were so sharp and clear that by using it, I look more skilled than I am (at least to non-photographers). The pancake size is so convenient to carry when traveling and hiking. Very pleased with my purchase!

                              This is my favorite lens for the price range. Although great for wide-angle, it has excellent depth of field down to 2-3 feet. I use this with my Panasonic Lumix GH3, and the picture is brilliant. Excellent for video including weekend warriors for weddings, etc. or the short film/indie features. I highly recommend this camera. I would recommend also getting another lens that can go macro for even closer-ups that this can't get.

                              Comments about Panasonic Lumix 20mm f/1.7 Aspheric G- Series Lens:

                              I recently upgraded to the GX1 from the LX5 and S95. I am a "casual enthusiast" who is trying to break into the world of interchangeable lenses and decided to get the 20mm 1.7 along with the 14-45mm. The 20mm lens is special because it's a normal wide that gives a little bit more than the 50mm FF that most people see. The lens has character and does something special to the pictures due to its really nice bokeh, crisp image quality, and corner to corner sharpness. The vignetting is also very low. Add this to the 1-inch depth, and now there's a must have lens, for low light and more, for 75% of the masses like myself who want to make sure they get the right equipment to grow with.

                                The Lumix 20mm F 1.7 is a must have - even though many argue that the 25mm 1.4 is a tad better - but it is also much longer and also more money - what I love about this lens is how slim it is. I mostly use it on my Olympus OMD-5 - a good combination.
                                Pretty sharp and pretty fast - and nice bokeh - well built as most of the Panasonic lenses are.
                                So even if you went with the 25mm 1.4 I would alos add this lens in the basket as it is so slim and 40mm is perfect for street shooting - I find 50mm sometimes not that practical for street shooting.

                                This lens is small, sharp and fast. And dig the shallow depth of field. Auto-focus does not preform well in low-light. And AF could also be a little faster and a little less noisy. But these are not issues for me in my studio. I use this lens with a GH2 for video recording purposes. And I generally use studio lights and an independent audio recording equipment when I shoot.

                                I love this compact lens. I've been dying to have a fast lens like this. Image quality is great, build quality is great.

                                I do think the autofocus is significantly slower than my basic 14-42 on my GX1. Would have been perfect except for the focus.
