Minolta Maxxium AF 50mm f1.7
50mm f/1.7. An inexpensive but very good lens. On APS (5D,7D & A100-A700 cameras) the 75mm equivalent focal length makes it close to perfect for a "short" portrait photography lens. The f1.7 aperture makes it very good in low light / available light situations. Ebay prices are typically $80-$130 (Nov 2008 - prices have been climbing!).
