Legacy Lenses
Canon EF 55-200mm f4.5-5.6 USM My first real telephoto. Some nice pictures from this.
Canon EF 75-300mm f4-5.6 USM Ok long zoom on an APS-C. Not the sharpest lens, and really needs a sturdy tripod.
Canon EF-S 18-55mm f3.5-5.6 Kit lens that came with the 400D. Not a bad lens. Again, some of the photographs on the site were taken with this. No use on the 5D though.
