Stoked! Am I going to like my 24-70L on that thing even more? I spend my days shooting portraiture and am looking forward to the change. The XS has been quite the capable camera though. I also have a wedding coming up (it's also paying for the upgrade) and am looking forward to photographing the LDS temple it's at with a full frame. There's a link to my studio page in my sig. I can say that the XS has been my favorite thing that I have bought in the past few years. I'm going to miss it : (. Anyone else made a jump like that, tell me about your experience!
