Yes, I would recommend this to a friend

Consistent Output; Durable; Fast / accurate auto-focus; Rugged; Weather-resistant

I got this lens second hand from Adorama but would be hard pressed to tell it from new. It came with lens caps and hood and a belt mounted lens case I wash't expecting. This lens is as fast as all the reviews say and at f2.8 resolves the issues I was having with the Olympus kit lenses (14-42mm) not...

Consistent Output; Easily Interchangeable; Fast / accurate auto-focus

Heavy

I bought this to replace my 14-54 because I wanted a wider lens with more reach. It was the only lens I took on an 18 day European trip and never missed any of my other lenses. If I could only have one lens, this would be it, without any doubt!

Excellent focal range; pretty fast (light); fast focus (especially on the E-3 or E-30)

Price; but it's worth it

Boasting a 5x zoom range and an f/2.8 maximum aperture the 12-60mm zoom looks impressive with its extra-low dispersion (ED) glass and responsive, fast-focusing Sonic-Wave Drive...

Lovely feel; useful 5x zoom range; great image quality

Low CA does not always mean high resolution

A standard zoom lens for Four Thirds format SLRs with a silent focusing motor covering a range equivalent to 24-120mm on a 35mm camera.

Excellent build quality; Good optical performance; Fast focusing; Useful minimum focus distance

Barrel distortion at 12mm

The Olympus Zuiko Digital 12-60mm 1:2.8-4 SWD was announced in October 2007, alongside the flagship E-3 DSLR. It's a standard Four Thirds lens which means it will work on any Four Thirds body, including those from Olympus, Panasonic and Leica, although it's physically best-matched to the larger...

Flexible 5x general purpose range, Quick and quiet SWD focusing, Excellent build quality; Dust and splash-proof, Very sharp results across frame and focal range

Shadow from popup flash on smaller bodies; Feels front-heavy on E-4xx series; No anti-shake on non-stabilised bodies; Imager AF not supported in Live View

We have chosen to use the Panasonic L10 as our standard test body for Four Thirds lenses purely because it gives the highest numbers in our resolution tests (which we believe is most likely due to it having a relatively weak anti-aliasing filter); this is intended simply to provide the fairest...

Very useful wideangle to telephoto range; Superb optics; Excellent build quality; dust and splash-proof; Impressive resistance to flare; Decent macro performance

Pronounced and complex distortion at wideangle; Slightly sub-par lens hood; Shadowing of built-in flash at wideangle on smaller bodies; Expensive

Designed for general photography, the new Olympus Zuiko Digital 12-60mm Pro lens is a high-performance standard wide zoom lens that is optimised for use with the E-3 DSLR camera.

Very highly recommended but price might be a little steep for some

The resolution isn't very high; solid build; lightweight; fast focussing and quite versatile

Slight but hardly noticeable distortion at the widest angle

The build quality of the lens is exceptional. It is based on a combination of metal and high quality plastic parts. Typical for its lens class the Olympus lens extends when zooming towards the long end of the zoom range. As expected the lens suffers an only very marginal wobbling of inner lens tube.
