Excerpt: I used this lens on Olympus E3 and Panasonic GH2. It's nice sharp lens. Unfortunately AF is way too slow, even with E3. I expected to be slow on GH2, but not with E3. Olympus, fix this! I returned this lens.
Pros: Easily Interchangeable, Nice Bokeh, Strong Construction
Excerpt: I purchased this lens to go along with my 3 other lenses for my Olympus 620 camera. This prime 50 mm, macro lens is a great addition to my camera collection. I use it to do macro photography of small wild flowers. I have had it only one week but have already I have gotten some great shoots. My only wish is it was a faster lens either a f1.4 or a f1.8 lens. I really wanted a piece of fast glass without spenting over $1,000 dollars.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I have a love and hate relationship with this lens. The lens optic is superb! Sharp even at f2.0. The problem is, you seldom can get the autofocus to work properly on your first try! The lens front & back focus and stop in between. Then, you press the second time and it's in focus. In low light, this lens search back and forth its full focal length and it's loud and undecisive. Sometimes it just hang there and is unresponsive.
Excerpt: This lens in good light will produce excellent image quality like the Olympus lenses do more often than not. However, in low light, the focus runs back and forth searching wasting too much time. I think one is better off using manual focus for macro work. I read about the slow focus, thought I could live with it. I couldn't, [...
Pros: Easily Interchangeable, Lightweight, Nice Bokeh, Rugged, Strong Construction
Excerpt: Only used this lens for two days with E-P1 body and DMW-MA1. So far I can say that portraits look good, but Pros: Very good image resolution, even wide-open. Fast lens. Creamy, smooth bokeh. Sturdy, feels solid. most aberrations are correctd very well. Macro and portrait at the same time. Cons: Strong sphero-chromatic aberrations. When doing close-range shots wide open, high contrast areas get very noticable green or purple tint, depending on distance.
Pros: Durable, Nice Bokeh, Rugged, Strong Construction
Excerpt: Being an Olympus faithful for many years and owning a few Zuiko lenses this is the one lens that they can improve on. The built quality is right up there and the fast aperture (f/2.0) is great, especially in lower light conditions. Image quality is truly amazing and tack sharp is the best way to describe it. So why not a 5/5 rating? 1. The lens is extremely slow and this is frustrating. The lens really battles to find a focus point in all modes, AF-S and AF-C.
Pros: Consistent Output, Durable, Easily Interchangeable, Lightweight, Strong Construction
Excerpt: I compared this lens to my ancient OM Zuiko 50mm f/3.5 macro lens, on an E-PL1. (Each lens requires an adapter - a $100 Panasonic adapter for the 2/50, and a $30 Fotodiox adapter for the 3.5/50). Center and edge sharpness appear slightly better with old 3.5/50. I found this result surprising, given the nearly universal glowing reviews for the 2/50. I guess the ancient OM Zuiko 3.5/50 macro lens is an underrated piece of glass!
