The message you have entered is too short. Don't worry Steve, we'll all believe that you're 49 next year too, because we don't know what year you were born.
Personally, I think ever owner of a DSLR with an APS-C sized sensor should own a 35mm F/2 and 50mm F/1.8 (or 1.4). I'd say the same for a full frame sensor, except for maybe subbing an 85mm F/1.8 for the 50mm.
