hey all, i have a $1,000 budget to get some better equipment for headshots. i take some decent ones, and more people are starting to offer me money to do their headshots, but my equipment is just not up to par, and i'm getting sick of renting it every time i need to take photos. my own equipment is a rebel xt, and that's about it. i rent everything else when i take shots. my research seems to indicate that the canon 85mm f/1.8 usm is a good place to start. that'll leave me somewhere around $650. now, what would you guys get next? my experience is with hot boxes... i like the ease & the even light, though i see much better results when i use them inside -- i've had a hard time adjusting the color temperature post-facto when the tungsten mixes w/ outdoor light. i'd appreciate feedback from those more experienced than myself here, though. would you look at a different lens? would you buy a flash w/ the lens, and continue to rent the lighting? i need a little guidance here. and yeah -- i know the xt is not the optimal body to use, but it seems good enough for me right now. i'm happy enough w/ it's results when there's a good lens on it. the body seems to be a purchase for a later date, when i'm more sure of this (potential) business' growth, ya' know? anway - i appreciate any feedback. thanks!
