Normal Lens

I have a f 1.8, 50mm lens, that until the purchase of a manual focus 55mm f 3.5 macro lens, had the distinction of being the cheapest and sharpest lens I own. The only drawback to the f 1.8, 50 mm lens, is that it won't focus very closely. This is enough of a problem on a reduced sensor DSLR, but would be even more of a concern on a film camera or a full format DSLR.
