So, I want to purchase a new Macbook Pro. Part of the purchase is a move away from having a desktop computer. To finance a new purchase, I will have to sell camera gear (because I'm a broke student but I have really nice camera gear). I'll be downgrading from a D750, Tamron 15-30, Nikon 85mm 1.8G, SB-700 flash, and some other gear. I'll be keeping my 50mm 1.8G and Sigma 150-600 Contemporary. I'd even consider selling the 50mm 1.8G, but it will serve as a good portrait lens (my copy of the 50mm 1.8G is quite sharp, I hear copy variation can be bad with the particular lens). The move will sting since I'm taking a nice loss on the resale of a lot of my gear. What crop camera should I look at though? I'm thinking about getting a D7100 used or on a sale, and looking for a good used UWA crop-sensor lens.
