Summary: Great lens, works very well when attached to the E5. Performs well, focuses quickly, by far my favorite over the others that I own. I gave 4 out of 5 because the only thing that I wish was different was the distance marker, wish it were more detailed.
Summary: I bought this lens to adapt onto my PEN EP-2. I think the image quality is very good, although, I mainly wanted to use the lens for making video. Unfortunately, the sound of the auto-focus gears can be heard with the camera's microphone. I use a Electronic viewfinder, so there's no other way to add a mic. The lens auto-focus also jumps around a bit too much. I wish Olympus would make a high-quality ( perhaps zoom ) fast lens for the EP series.
Excerpt: Very sharp, fast and heavy. I use an SLR mostly to photograph flat art where I need a better tonal scale than smaller sensors. At around f5 the lightweight, inexpensive kit lens image quality looks about the same so I returned the 14-54.
Excerpt: Without a shadow of doubt a much better, brighter, sharper lens than the usual kit lens. I use this lens for everything from underwater to panoramic and highly recommend it. Great macro (considering it's not a macro lens) and good shadow detail.
Excerpt: I bought this lens as an upgrade to the 14/42mm lens that comes with the kit. Overall, i'm very happy with the lens, and would recommend it as an upgrade. I've compared the shots taken with this lens against the kit lens, and where the 14/54mm excels is in lower light indoor conditions. The pictures contain a lot less artifacts, and the barrel distortion is also much more minimal at 14mm.
Pros: Durable, Easily Interchangeable, Rugged, Strong Construction
