Canon EF 17-40mm f/4L USM

This color rendition and contrast of this lens is fantastic, as is the autofocusing. I bought this lens as a walkaround for my 30d, and i surely blows the kit lens out of the water.

When using this lens on full frame cameras, I have noticed the the corners are quite soft and vignetting is somewhat substantial. I can't really complain about this though, because it's inherent with most wide angle zooms.

That said, it's a fantastic alternative to the 16-35L if you don't need the extra stop.

Oh yeah... the hood is useless on a 30D or crop camera.
