10 out of 10 points and recommendedIQ, costAutofocus issues, craftmanship
OK, that's my fastest lens. And the cheapest. However it has one trick in it's sleeve and it keeps me coming back to it: IQ. When focuses (most of the time) it provides great detail, crystal image and unmatched for this price low light shooting. Using it with Canon 5D was a shock. No flash was needed most of the time. With the 40D it made me realize that focusing is a bit of an issue. Mostly in low light situations. In bright daylight all is razor sharp.reviewed December 30th, 2008 (purchased for $80)
9 out of 10 points and recommendedIQ, costtoo big for Canon XTI etc.
This is a very big and same time exiting lens. Wide front and hood may be too big and heavy for small cameras. Even my Canon 40D needs a grip if shooting/focusing for too long. Talking of focusing: most of the time if focuses fine but may not be perfect in low light condition. Image is a bit soft and much vignetting is an issue on full fram DSLR such Canon 5D. However it works just fine with the higher end camera bodies.reviewed December 30th, 2008 (purchased for $230)

This is the most affordable 18mm EF-S lens. Therefore we can't live without it. I was debating to stay with my 24-60mm zoom but the 1.6 ratio worked against that. You need at least one wide angle lens and this is the best candidate. It does only one thing: offers the "super wide" lens the DSLR desperately need when shooting landscapes and large group of people.reviewed December 30th, 2008 (purchased for $60)
