Handling and features This compact ultra-wide angle zoom lens for Micro Four Thirds system cameras offers a 2x zoom range equivalent to an 18-36mm lens on a 35mm camera. It costs around ￡450 and sports a collapsible design.

Like any concept, the Four Thirds imaging system has its pros and cons. On the plus side, camera bodies and lenses tend to be very compact, but then the four/thirds aspect ratio that's in keeping with pre-widescreen viewing screens now looks dated.

Very nice and compact wide-angle, but the price, moderate f-stop and focus distance limits this to specialty users who need wide-angle for scenery or architectural shots outdoor during the day.

Easily Interchangeable; Fast / accurate auto-focus; Strong Construction

The Zuiko 9-18mm provides dramatic ultra-wide angle performance at an affordable price. The lens is compact, light and seems sturdy. Images are sharp with vivid colors.

Great at capturing wide angle images, landscapes, and even portraits with somewhat unusual angles; It is very lightweight and portable and works well with the E-520

Perhaps not quite as sharp as some of the higher end lenses but more than acceptable for the price; Images tend to show barrell distortion at the widest angle; Sometimes difficult to use with a flash indoors at the widest end as shadows caused by on camera flash are visible.

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

Following the micro 4/3 philosophy, is a lightweight wideangle zoom, an angle of view comparable with a 18-36 equivalent in 135 mm or full frame. The cost difference is much wider than the quality diference, comparing with other micro 4/3 wide zoom as Panasonic too.
