Panasonic Lumix G 20mm F1.7 ASPH

Very nice and sharp pankake lens, well made, a must for indoors and night shot. Problems: A bit over rated, so the expectancy is higher than I get.

AF of the Panasonic 20mm f/1.7 is VERY SLOW and NOISY on my Olympus OM-D E-M5. Not Acceptabe for me. Lens might be "fast" in the aperture sense, but AF is slow w/ lots of seeking & noise. Got this lens to be an indoor "party" lens - the loud and slow AF make this lens unsuitable for that task. I traded my Canon 5D and all my Canon kit (50mm f/1.4, 28-35L, 70-200L, 85mm 1.8) for an OM-D E-M5. I LOVE the E-M5. Love the retro silver look. Love the small and light size. Working on customizing and ...

When I'm inside and all else fails I turn to this lens and get good images time after time. Sharp, great contrast and excellent low light performance due to the relatively fast aperture I'm really very satisfied with this as a great general purpose lens. Tend to use it a lot at parties and social gatherings, the small size and good performance really are at a sweet spot for jacket pocketable photo equipment. Problems: `

This is a great lens. For me, it has the perfect balance of sharpness, size, bokeh effect, and focal length. This lens can be used for "environmental portraits" and can be taken anywhere without being conspicuous. I also use it a lot for indoor pictures.

The best NORMAL lens for m4/3. Small and sharp.

Lovely lens. Flat pancake suits PEN. Obvious vignette at f/1.7 but this adds to the look of the photo. Problems: Slow AF on PEN E-PL1 because focus moves all the elements, not internal focussing. When set to f/2 or brighter, PEN still liveviews still at f/2.8 so the deeper DOF in Liveview may deceive you. Iris blades loud in action as PEN adjusts light passing through during Liveview

This is one of the three (m. zuiko 45mm, m.zuiko 12mm, lumix g 20mm) greatest lens ever created for 4/3 system. Problems: Not suitable for video shooting because the cracking sound created by the aperture blade mechanisme.

I bought to use on my olympus epl1 as a low light carry around at night but until now only used on my gh2.Seems sharp enough for me. focus is good but a bit slow .For video there are some issues.If you re focus when using video you can pick up the clicking from the lens by the mic so not that good for making video with sound if you need to re focus.Great for carrying around as its so small and on the epl1 I can slip it in a coat pocket

Sharp and fast lens that is easy to use and captures low light subjects well.

In the ~2500 shots I've taken since I got my E-PL2, my very favorite photos have been from this lens. Doesn't matter the conditions or situation, this lens has a special quality that produces outstanding and consistent photos. Problems: None
