Hello, I'm new to this forum and other than recreational photography, somewhat new to photography. I currently have a Canon EOS Digital Rebel XT w/ a 18-55mm lense. The lense is the stock lense the camera comes with. My wife has gotten into portrait shooting and we are looking to upgrade the lense as it seems like it is difficult to find the right lighting all of the time. We have lights, backdrops, backdrop stands and some props. Our lights are hot lights, and at some point I would like to upgrade those to strobes. I would like to get her a new lense that would be better suited for portrait shooting. Most of her portraits are of babies, children or belly pics. I was wondering if there is a lense or a couple of lenses that you would recommend. I'd like to hear about anything from the most expensive lense to the cheapest. Of course I want it to serve its purpose and all. I would also like to invest in a telephoto lense so I could shoot some sporting events. I'm most interested in using it for taking bicycle racing pictures. Like I said I'm pretty green at all of this so if anyone has any suggestions other than just lenses please let me know. We have taken some really great pics with our current lense but I'm looking to move forward. Thanks.
