Nikon lover here too :) I'm actually only using the 7200 right now. I've held off buying a new body in favour of my glass addiction. That cheapie Nikon 50mm F1.8 is one of my favorites, though!

I'm going to Iceland later this year, and I'm thinking of picking up the Sigma ART 20mm before I go...but have a few months to decide how best to beggar myself!
