I also use the EOS 350D. It seems that a few people here use the same camera and I believe recently that it was the camera that had been used to take the most photographs on flickr.
Currently I only have the standard 18-55mm lens that the camera came with. But I am hoping to purchase a new lens and some filters. While I am at it, I am also trying to make a budget studio out of my spare room. I would be interested to hear from anyone who has perhaps made their own studio.
