I'm seriously thinking about upgrading to a 5D II through the loyalty program. I currently have a 50D, Rebel XSi, 60mm macro, 85mm f/1.8, nifty fifty, 18-55mm IS, Tamron 17-50 non-VC, and a lensbaby 2.0. I'd have to sell off both bodies, and the macro and kit lens.
Are the remaining lenses good enough to get close to the potential of what a 5D Mark II is capable of? I shoot mainly portraits and landscapes.
