Well I mostly photograph action sports such as snowboarding, skiing, and skateboarding and I need some help choosing some new gear. right now I have a rebel xt with the kit lens and a 28-90mm. I can get a lens for christmas with a limit of about $1000 plus I have about $700 of my own money. This is what I was looking at getting: A tripod: Manfrotto 055 Tracker Tripod: $240 head: Induro SA-0 SA Tripod Head: $60 Lens: Canon EF 17-40mm f/4.0L USM Wide Angle Zoom: $860 Total spent: $1160 Left over: $540 What could I get with the remaining money or what could I change about what I want? I have a good bag and I don't want/need a flash.
