Amazon offers the Canon EF 50mm f/1.4 USM Autofocus Camera Lens, model no. 2515A003, for $336 with free shipping. That's $3 under our mention from last winter and the lowest total price we've seen for a new unit. (It's also a current price low by $4.) This 10.2-oz. lens can be used with Canon EF-mount SLR cameras.
