Summary: This is a good all around lens, not super sharp like a prime, but has a good focal range. The Macro Mode is a plus, it is not 1:1 but with the x2 crop it gets you real close(I use macro rings to get even closer). I was on a budget and wanted a good multipurpose walk around lens.
Excerpt: The decision to buy this lens came after much deliberation. Compared to the 14-42mm retractable lens I had on the Pen, this lens is far better: it is sharper, faster on focus, wider and longer. The near-macro and electronic zoom functions are very nice too. For $ in kit, this lens is a steal. The one demerit is the aperture range, slow to my taste. On the beat, I have not had to push the ISO beyond 1600 (no problem for the E-M10 sensor).
Pros: Adaptable, Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Summary: Bought used (but in what appeared to be as new condition), from a big NY City retailer. I have not tested it in the rain (yet) with my E-M5, so unsure how it will perform in that respect. Otherwise a versatile lens that takes a little getting used to. The motor zoom is odd, but better than manual zoom as the zoom ring is stiff. Macro mode works fine, a shame it is locked at one focal length.
Summary: This is a jack of all trades lens. Master of none, but if you get this for under $250 it's a great deal. Considering the slow aperture and the complaining by the elitist snobs, it's really not a bad lens. I find the IQ quite acceptable at the wide to middle end. IT is soft at 50mm and not ideal for portraits in low light.
Summary: As a professional photographer, I use this lens on my MFT when I want to travel extra-light, packing a 100-300mm telephoto zoom along as well. This lens gives a good range of focal lengths, from wide angle 24mm equivalent to 100mm equivalent short telephoto (ideal for portraits). At the wide end, I shoot architecture and landscapes. There is minimal edge distortion and the lens focuses reasonably fast. It is a good choice at this price point.
Overall a good lens that is well made and versatile.

Summary: I purchased this lens used for my Olympus E-P3. I own the Olympus Micro 14-42 but wanted to sell it with an E-PL1. After reading many reviews I decided to purchase it. I expected it to preform as it does and am very satisfied with the lens build, a very well made lens. The macro function is delightful although the lens is slow at f:6. It focuses fast enough and accurate. I do like the dual zoom functions: manual for photography and motorized for video, a nice feature.
Summary: I have read many negative reviews of this lens. I was surprised to find that it works well with the OMD especially when in movie mode and zooming. a prime lens will give better performance, but this lens hold its own for most of the range of 12-50MM. I do mostly slide shows using Photodex Producer, so I can't use all the pixels and resolution a print maker needs. Thus, this lens does a great job for what I use it. Any vignetting is easily corrected in Lightroom.
