The Sigma Normal 50mm f/1.4 EX DG HSM Autofocus is fairly priced ($ 500) and offers good performances, of course based on charts.



Possibly built quality is not super, but I am rading less disappointed opinons on line compared to the Canon 1.4. In fact, Mark's comments in this thread seem to be matched by few others in other forums/shops here and there.
