Congrats and your DSLR purchase! I have the 75-300 Canon IS version of the lens. The IS (image stabilization) works great. As far as the lens goes well I have a mix bag of feelings. I have taken some great shots with this lens, but I have missed some shots due to the slow focus. The 70-200 F4 L lens would be a great choice to start out with. The 75-300 is pretty sharp up to 200mm from there on it is a little soft. Enjoy your new camera and lets see some photos.
