I've just made the big jump to FF and now I'm considering parting with my XTi. I don't see a reason for me to own a 2nd body since I'm just a enthusiast and look at photography as a hobby, albeit a serious one. The idea of carrying around my telephoto on my XTi along with my standard zoom on the 5D sounds enticing but I honestly don't see the need for that. I suppose the loss of the crop factor is the only thing that I'm worried about but even then I doubt that I will miss the extra reach that much and I could use the money gained from selling my XTi to buy a prime (I'm currently primeless).
I've pretty much decided that I will go ahead and sell the XTi but before I did I wanted to hear what other POTN members used their 2nd bodies for and what their justifications for having one were just so I don't end up regretting this a month or so from now.
Thanks in advance, guys.
