New found freedom away from zooms - a true walk-around lens, February 9, 2010

By Jimmy Ferrara "guitarist(surf*blues*funk)/com... (Northern VA, USA)

I am using this lens on a Panasonic Lumix L1 and took it to a large party/rehearsal dinner where people were frantically milling and mingling around and I really enjoyed weaving in and out of the crowd snapping candids with this lens. It was so refreshing not having to worry about fiddling with a zoom ring and allowed for rapid point and shoot style shooting that gave me a great advantage in capturing the flurry of the moment and great candids.

I only gave it 4 stars because of the following: 1) as others have stated in photo forums, this lens, after you screw it on about 2/3's the way, the last 1/3 of the twist is very hard to do because it is a extremely tight fit so much so that it feels wrong. None of my other Olympus lens' fit like this -- they all twist on firmly with ease. 2) this is the first Olympus lens I've purchased that is made in China (all my other ones are made in Japan) 3) I feel this lens in over-priced for a fixed lens, especially a pancake that has very little glass in it and is also made in China -- this lens should cost around $150. (Because of the bad fit, I may send this back and try another one to see if it fits better)

For those of you who own a Lumix L1, I can tell you this is the lens that should have been supplied with the camera as a kit lens -- it changes the whole attitude and functionality of the camera, and finally, the L1 has a lens that matches its range-finder body style. This lens just encourages the joy of shooting by enabling you to concentrate on your subjects.
