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.
Summary: I have an Olympus E-520 bought together with the two kit lenses -- 14-42mm f/3.5-5.6 & 40-150mm f/4.0-5.6. After using them for a while, I decided I wanted a faster base zoom lens for low-light, non-flash conditions. I chose the Olympus Zuiko 14-54mm f/2.8-3.5 lens. When it arrived last week, I spent a day taking comparison shots with the 14-42mm kit lens. The camera was used in Aperture-Priority mode to allow comparable settings. Image stabilization was always on.
Summary: Got the 14-54mm lens in time alright. It didn't look quite as "new" as the ad said it was "used-like new". It didn't look it beat up though for a used item but it was far from the other "like new " items I've ordered from you before. Scoring "new" as a 10, "like new" should be about 9 or 9+. I rate this item 7 or 7+. Not even an 8. It didn't have a rear cap, and the hood was really scratched I had to buff it to make it look presentable.
