Summary: Optically an absolute disgrace. Build quality also extremely poor. the plastic case at the end (where focus window is) fell off of mine. Hood is also very flimsy in the way it's attacted (not a bayonet). I own both the 28 and 50mm USMs - they're optically good. I'd like to use a 35mm, but this is just unacceptable in every respect, mine is never used.
Summary: I received this item in very good time and in good condition. This Lens although reduced I believe is still too expensive, because its build quality is not great, and I didn't consider it that wide angle really. I think lens prices are ridiculous, the newest version of this lens I believe is £600 or more. Photography has always been expensive, but these days one has to spend money stupidly.
