Hi, I need a small mini tripod that's capable of holding a D2x and 17-55. I've glanced at a few, but they all appear to be made for compact cameras. Do I have any options, or am I forced to get a bigger monster? I want something as small as possible, as I don't have a problem finding something to rest it on, but I need more flexibility than a steady bag will lend me. Anyone have ideas? Thanks!
