Full frame on a budget?

Hello so I currently have a crop sensor Nikon d3300, very entry level, not so great for what I shoot now. I think it’s time to upgrade, and need advice. I’m not willing to leave Nikon, due to me having some pretty great lenses. I was looking at the Nikon 610 it’s full frame sensor but it’s old like from 2013 old, but still an improvement from my 3300 never the less. Thanks for any advice! Sorry if it’s a jumbled mess I’m riding in a car atm.TLDR: I need some advice on what budget Nikon full frame sensor to get, thanks! via /r/photography https://ift.tt/2SHtkxk
