So yeah, I got a Digital Rebel XT. I'll still use my G6, it does better than my kit lense for macros and for carrying around.
I'm happy with it, although I have to admit it has taken some getting used to not being able to preview the exposure and whatnot on the LCD. It's kind of been forcing me to think a bit more about my camera settings.
Anyway, hopefully over the next few months I'll figure in which ways I find myself limited by the kit lense and buy another.
Enjoy the photos, if anyone reads this.
