I'm a newbie with my first SLR D30. I have a Tamron 28-300mm f3.5 . I want a lens to shoot bands at clubs in low light situations. B/H has a Canon 50MM F1.4 USM AUTOFOCUS HIGH SPEED LENS listed at $294.00. Is this a good deal? I never bought anything off of eBay and would like it to be new anyway. Any help would be appreciated. Peace MJEXP
