This lens is not the sharpest, particularly at the long end. However, it's biggest flaw is that the projected image circle doesn't cover the entire sensor at 14mm, leaving your raw files with black corners. When the image is corrected for barrel distortion, the corners are pushed out and the occlusion is no longer visible. If you don't want to correct the distortion then you will have to crop the image to remove the defect.
On the plus side the lens is very small and light, so it can go along when larger alternatives are not practical.

Great all-in-one travel lens that makes the PEN a little larger, but a far better travel companion than a full DSLR.

This is an ideal lens to use with the Pen cameras, in addition to the 17mm 2.8 of course. With these two lenses you are set for just about any travel adventure. The lens has a metal lens mount, and considerably faster focusing than the 40-150mm. It is well made of high quality plastic, which allows for a small size and light weight, the whole point of the Pen system. I found this lens ideal for photos of the kids, as well as travel and landscapes. It is fairly sharp wide open, very sharp one to two stops down, paricularly sharp in the low end of the range 14-50mm, and very respectable in the rest. It is also very quiet while in video mode, not distracting like some other brands. I would recommend using the VF-2 for this lens though, especially at the long end. Even with stabilization you won't get the sharpness you expect holding the camera at arms length to see the back screen. You will have many more keepers holding the camera up to your eye to keep it steady. While it costs a little more than the 14-42 and 40-150mm combined, it is worth it in my opinion due to convenience, construction, optical quality and focus speed.
