Raynox DCR-250, Macro-Scan 2.5x Super Macro Conversion Lens, with Snap-on Universal Mount for 52mm to 67mm Filter Diameters. Will this fit on my Canon rebel XSi with the EFS 18-55mm lens on it? Or will I need some kind of attachment? I love taking pictures but I guess I'm not as serious as all the people on here. I love to take close-up shots of flowers & bugs...but don't want to use extra lighting & tripods. I just want something inexpensive to help me get closer!!! Thank you! I enjoy looking at all the pictures on here!
