I'm considering a Canon 6D, the worlds smallest, lightest (read cheapest) full-frame DSLR. I have another wedding to shoot in May, and read that a second body is good insurance in case the primary fails. I have my point-and-shoot, the Canon G1X, but figure I'd be lynched shooting a wedding with a P&S. Ideally, I thought, I'd have another tiny SL1. But then fellow photographer Miss Julian Gray purchased a used 5D and began extolling the virtues of shooting full-frame, which brings us to my 6D rental. Sadly, the three wide-angle lenses I have are all EF-S (fitting only APS-C) so will unfortunately have to purchase an EF wide-angle if I, too, chose the full-frame route. Probably something absurdly expensive like the Canon 8-15mm f/4L. I get anxious about buying too many expensive items too close together, this on the heels of the new Flex :/
We'll have to see how it goes. I have a waterfall shoot scheduled for tomorrow.
