This is a very interesting lens, because it doesn't have the best reviews online and has been recently discontinued. It was actually the world's first SLR lens with the Image Stabilizer feature built in.  For a first generation product I think this lens does exceptionally well, and it's a lens I very much enjoy using.

This is another one of my favorite lenses, and one I'd highly recommend the new photographer or the enthusiast on a budget.  This is actually one of the cheapest Canon lenses that feature true Ring-Type USM focusing for excellent speed and silent operation.  If you have never tried one of Canon's true USM lenses you'll be in for a treat.  I use this lens with Canon's EW-63II Lens hood.  It's a little expensive, but it fits well and helps improve contrast and reduce annoying lens flare.

This is easily by far the best value of any EOS lens that Canon sells. I highly recommend this for ANY photographer, no matter what your subject of interest is. It is a prime les of 50mm which is in a fairly good range for portraits.  This is often the lens I use for close up portraits, and it's also the lens I use in low light situations because the lens lets so much light in.

The main camera I use for my photographs is my Canon Digital Rebel.  This is a 6.3 MP Digital SLR (Single Lens Reflex) that is a couple of years old now, but I find it has nearly every feature I need.
