Superb metal build quality; Good AF/MF control; Hyperfocal scale; Excellent optical performance in the centre at fast apertures

Premium price (although in this case; you get what you pay for; No hood or case provided

On the Olympus PEN E-P3 body we used for this review, the lens focused quickly and quietly. AF speeds were extremely fast, with the lens locking on to the subject almost instantly in most cases.

My favourite wide-angle for use with MFT had previously been the four thirds Olympus ZD 11-22mm f2.8-3.5 lens, which I eventually and regretfully sold. But this new lens outperforms the zoom comfortably.

Absolutely superb build quality and good looks; Fast and reliable auto-focus and very useful 'snapshot' manual alternative; Colours and contrast similarly outstanding, and corner to corner sharpness can be obtained from f4 onwards.

None; so long as you can afford it

The M.Zuiko Digital ED 12m f/2.0 lens is a 'fast' prime lens that covers a field of view equivalent to a 24mm lens on a 35mm camera. Ideal for landscape photography, its wide maximum aperture also makes it suitable for candid and street photography in poorly-lit situations.

You want a well-built; wide-angle lens with quiet autofocusing for shooting video; You'd like to explore the creative options of the wide maximum aperture; You want good manual focusing

You need close focusing and macro capabilities; You require excellent edge-to-edge sharpness.

Trying to convince your wife to let you buy a $650 lens when you already own the Oly 45mm, Panasonic 14mm, and Panasonic 20mm is no simple task. But as luck would have it (and 2.5 glasses of wine), she agreed and I made the purchase before she realized what she had agreed to. No regrets though.

The best 24mm lens(in 35mm format)with high image quality and construction. At f/2, it is possible to shot handheld in the night. However, the lens is considered expensive. If you are a zoom lens fan goes Lumix 12-35/2.8 or 14/2.5 for much more economic choice.

I'm a wide angle snob but I must say this lens does meet my expectations. Low distortion, and fantastic image quality out of this lens. One of my favourite shots out of this lens is this one: http://www.flickr.com/photos/kinematic/6174448530/in/photostream Superb build quality and although I am a...

Fantastic build quality; super fast AF; snap focus ring; low distortion

Expensive, no lens hood or pouch included; Kind of pointless wide aperture

I do a lot of street/candid photography and bought this lens to give me a wide-angle option alongside the Panasonic 20mm f1.7 and Olympus 45mm f1.8. I use a Panasonic and Olympus camera bodies (GF1, G2 and E-PL3.

Compact; Durable; Great Features; Great Picture Quality; Lightweight; Simple Controls

No Supplied Hood; Pricey; Silver Only

Beautiful jewel of a lens! I have the 12-40 F2.8 so was hesitant about buying a focal length I already had covered. But this lens has twice the light gathering ability as the zoom and is really small so great for taking out when you don't want anything bulky.
