If you really want to spend all the money on glass, you can't go wrong with an Xpro1 though. Yes, it is slow in some situations. Yes it has quirks, and sometimes I find myself cursing it on the street. But generally I love it, and it takes amazing pictures, being old doesn't stop it from being good.
