ownership:I used to own this lens
compared to:35mm f2, 50mm f1.7, Sigma 70-300 APO.
price paid:Ł180 (new)
positive:Has produced some excellent images.
Good bokeh.
Excellent zoom range.
Decent construction - has already taken a fall and survived.
Good manual focusing ring.
Great sharpness when stopped down.
f3.5 at 18mm isn't bad!
negative:Very rarely (only had it happen once) totally fails to AF when shooting into extremely bright light at wide angles.
Vignettes quite heavily at 18mm with a polariser - would probably be better with an ultra thin version.
Slow aparture, especially at longer focal lengths.
comment:Outdoors, in good light, it's fantastic. The zoom range and general quality stand out, and as long as you acknowledge the vignetting with a polariser, it's no big deal.

Indoors, or for something more intimate like a portrait, I prefer primes - it's not an expensive zoom and shouldn't be expected to perform like one.

Highly reccomended for the price.
