I'm still going back and forth. My 80D is filling my current needs and I"m not really sure what the addition of FF is going to do to help me. It's a want vs need. I've been watching youtube videos all morning. The haters are out in force. Jared Polin did a pretty balanced commentary. I'm prob going to just keep plodding along developing craft until I hit a point where there is something specific I need.
