hey! I also have a Rebel XT, addictive little thing isn't it?

I bought my camera as a big kit with all sorts of do-dads... I have the stock 28-90 (??? I'm at work, it isn't) and then I have a 70 (75?)-300 zoom. I don't know what that lense retails at, but I really love how it performs. I also scored a 100mm macro off ebay for half the retail price, and it was new... oh I rejoiced that day!
If you'd like to see my pics just go here... you can get an idea of how they both perform. The outdoor critter pics were mostly taken with the 300 zoom, and then almost all of my tank shots were taken with the macro. It'll be pretty obvious which is macro!
