Thanks all, I like the suggestion of buying a cheap, used aps-c as a full-around with video and timelapse kinda body. Makes a lot of sense as I would not be shooting events/portrait sessions, etc. I do love the 50L as it acts as the body cap on my 6D whenever I'm not specifically shooting something else. It's definitely the "grab the camera and go" lens for me. I was just looking through some of my pics and noticed I really liked my 35mm pics when I had the 35/2 IS. I was just thinking maybe it was better to have both FL options plus a full-around body using simply one 35mm prime. I do see your points about losing the DOF control with the 35 on aps-c though, and I probably don't want to give that up just to have a faster 35mm option for FF when I prefer 50. I'll keep saving, and try to curtail the GAS itch for awhile
