Fast, top notch built quality, good size, sharp.... there is nothing bad to say about this lens. Anyone has E-series should get this lens.

I've been using this lens for about a year, after using the 14-42mm kit lens which came with my E-520. The sharpness and color accuracy of this lens' images have to be seen to be believed. Flare is almost non-existent. Autofocus is extremely fast. Portraits taken by it look totally natural. There is nothing I don't like about this lens. It's improved the standard of my photography and motivated me to be more creative.

I am not an early adopter in investing lens, use standard kit lenses for more than 4 years starting 2006 for my E500.
Recently I bought 12-60 SWD lens (after read many review and see sample images).

Result: very satisfied, detail is good. Most amazing is: at 60 mm can shot object only 10 cm from the lens, semi macro usage provide very sharp image and good detail.

At medium range object focus on the object at lower aperture is very nice, own creativity is the limit.

I have no hesitance to recommend this lens to anyone who want to get the most of your Olympus gear :)

I've shot professionally with many different cameras and formats from film to digital for over 30 years and this is one of the few lens of any type that I've been extremely happy with using. It's sharper, smaller and more durable than anything that's out there.
Digitally the sharpness is amazing with perfect color. I'm happy to have switched brands to use these lenses.

I am an advaced amateur photographer with sixty years of experience with large format, medium format, 35mm, and digital equipment from all of the major brands. Never have I been so happy with a lens. I first bought it for use on E610, and now use it with the E30.

I shoot mostly landscapes, panoramas, travel, and architecturual subjects, so the wide angle suits my style perfectly.
