This lens is fill my expectantions.

The build quality is pretty good for a retractable lens. In its transport position the lens feels tight and solid thanks to high quality plastics. You've to move the lens to its working position prior to being able to taking pictures - this is as easy as simply zooming from the transport position to...

Unbelievably small size for the scene it covers. Contrast is good, detail is moderate (i.e. detail would begin to get fuzzy after approx two levels of zoom). This happens on most ultrawides and cropped sensors due to the span packed on a small space.

Lightweight and very affordable

Softness and sluggish AF

Overall the 9-18mm is a winner for me. Its combination of compact size, low price, and good image quality make it an excellent choice for urban cityscape as well as nature landscape photogrpahy.

Excellent range of focal lengths Compact design Lightweight Good image quality Reasonable price Functions well with the Olympus E-P1 (w/adapter) Balances well with the entire Olympus/Panasonic range of cameras

Slightly slow (faster maximum aperture would be nice for street photography) Focusing could be faster (SWD would be cool) Concerns about long term durability in the field (probably not an issue; and heavier duty construction might add substantial weight

I purchased this lens to round out my selection of lenses. For the value, this lens has provided me a great option for those situation where a wide angle lens is needed to capture that image and include the background or to capture that up close image yet
