and I love it. For the money ($165- through Amazon), you can't beat it. When I first bought my 400D I bought the 50mm 1.8 to go along with it. I used it a ton at the beginning since it seemed to be so much better than the kit lens. I used the kit lens every now and then but never really liked what I saw. 3 months after getting my camera I bought the 28-135mm 3.5-5.6 IS and started using that a ton. It's a great a lens but I'm not sure if I knew how to use this lens but it was supposed to be great so I tried to figure it out. After a while I decided to go back to the 50mm 1.8 since it was so sharp and you could get some great DOF with it. I worked that lens for a while and felt like I really understood it. I used it to shoot a bunch of rock shows and was real happy with the results. The only problem with the 50mm 1.8 is that all my rock show shots started to look the same. Since my kit lens wasn't fast enough, I picked up a used a Sigma 24-70mm 2.8. I thought I had finally gotten the perfect lens to shoot bands. I tried it out and loved the wider angle I was getting but I hated how soft it was at 2.8. No point in really using the lens if it wasn't sharp so I returned it. I ended up trying to use my 28-135mm 3.5-5.6 IS. I had always heard you couldn't shoot a rock show with anything slower than a 2.8 lens. I figured I had nothing to lose since I really couldn't afford anything better at the time. I ended up getting some great results with this lens and switched between it and the 50mm 1.8 when I photographed bands. At some point I really started to figure out how great wide angle shots were. I started using my kit lens for everything just so I could get a little wider. My shots weren't tack sharp but they looked so much better. I didn't really take the lens off my camera for about 2 months. I really felt like I learned how to use the lens and get the most out of it. Once I heard that Canon was releasing this same lens but with IS I knew I had to pick up a copy. The 18-55mm 3.5-5.6 IS is super sharp at 5.6 and is great for photographing people.
I also used it for photographing "The Kooks" (British rock band), and was blown away with the results. I finally have a lens that is fast enough to shoot a rock show, and wide enough to get some amazing angles.
