Cons: Autofocus on 4/3 bodies is unreliable, especially at wide angle.

Pros: optical quality, speed, build quality,

Summary: A work of art, surely the best standard zoom ever created. I need say no more about its quality, it's just that good. But unfortunately I had problems with focus accuracy on ALL my Olympus bodies. A replacement lens was exactly the same. I found the 14-54 much more accurate, and kept that instead.

Cons: A bit dark in the tele end A bit expensive Would need a bit more contrast/color capabilities compared to 50-200

Pros: Great focal length IQ and contrast/color handling is well balanced with the focal length, but compared to 50-200, it feels a bit lame. Amazing all-rounder Weather sealing Well balanced with E-3 and E-5 Works almost as a macro lens, focuses almost to the front lens in 60mm Fast focusing Haven't really regretted buying this lens!

Summary: Great lens. If you need one all-rounder, this is it! 12@24 mm is great for wide end and 60@120 gives you a bit more edge compared to other basic-zooms. If you are running on tight budget, you should consider 14-54 f2.8-3.5 if the extra millimeters aren't your thing. The 2 mms in the wide end are probably more important than the 6 in the tele end.

Cons: Can't really find any.

Pros: + Decent aperture range + Fast focus! + 12mm wide end! + Weather sealed

Summary: A bit heavy for a travel lens, but the weather sealing, big focal lenght range and decent aperture really make this a great all-around lens. I have always felt a bit limited with the Zuiko lenses' 14mm wide ends, but this lens starts from 12mm, making a really nice wide angle view. Autofocus is fast. I can get my E-3 misfocus only if I focus on a blank piece of paper or other totally non-contrasty object. Still haven't had many opportunities to use AF-C. This is the lens I usually have on my E-3 for event photography or just walking around. Lenses like this make the 4:3 system so beatiful.

Cons: Sharpness, versatile focal lenght, fast focus

Pros: Weight, F4 @60mm, price, Slow AF in LV, tends to hunt in LL

Summary: The whole lens adds another 100g of weight in comparision to the 14-54, however, the image quality and the versatile focal lenght of 12 to 60mm makes it truly worth. I have it on my E-620. Well balanced, tack sharp, fast AF makes this to one of the most versatil lenses of Olympus with superior image quality.

Cons: Reviews say it has a small amount of wave distortion at wide angle. I have never seen it ia any real world shots.

Pros: This lens and the 50-200mm SWD are the two best reasons to own Olympus. Huge zoom range covered with two really great lenses.

Summary: If my stuff was stolen this lens would be the first lens I would repurchase.
