depends on your expectation. It is not a technically wonderful lens by any means. But i keep it on my old epl1 in the glove box or my coat pocket and use it when an opp presents itself. Its fun. Cheap. And as long as you don' mind the zone focus gets shots i otherwise would not get due to not having a kit with me. Love it these winter months when work kills all my light
It works fine with my E-PL2. Makes for a nice compact pocketable camera. But it has it's limitations. You must have decent light and it'll do fine. This one and a few more were taken with the lens. http://wrw.smugmug.com/Landscapes/Snowy-Weekend/27782923_TMxFmJ#!i=2344862487&k=JsRdh3w
I use it as my lens (and cover) of choice. Drop it in you pocket and your ready with excellent photos at a moments notice. It has such a wide DOF that, except for close objects, you don't even use the zone focus lever.
Only draw back on any camera is loss of EXIF. I use ExifChanger on my Mac to add the data back in with a preset One nice feature you don't have to worry, just set f stop to 8 always. (I have about 20 legacy lenses with presets to add EXIF data.)
