Sol - thanks for the considered thoughts, given the limited information I've provided.
Indeed, I'm wondering if she'd notice the advantages of a newer camera. She mostly does framed shots (lots of people posing) and some "action" shots (PJ-style). She's recently been looking into bracketing options and other things to try to grab a few quick shots in a row for those times when people don't sit still. A larger screen would be a huge plus given the way I've seen her work (take a few shots, review them and see if she's got what she thinks she wants). She's progressed beyond just point-and-shoot but is still learning intermediate-level things. Low-light options would be nice, as she does a lot of shooting indoors and at dusk, and January in Minnesota is rather dark on many days anyway. She has a single lens, so perhaps a second lens would be an obvious thing to look into. I just got her a larger CF card, but that was all of $30.
She has a nice, study tripod (my dad's from back in the day when a tripod had to hold a 20 pound VCR camcorder), but perhaps a smaller, portable one would be nice. I forget what those really bendy ones are called, but I have a friend with one who likes it.
