Pulled off the highway to get some sunset shots with my RB. Had the 50mm on it, didn't like the frame from my position, slapped the 180 on the front and went to shooting - must hurry, rapidly changing light etc. etc. Now I realize that I forgot to pull the lens adapter off the 50 and put it on the 180 before I mounted it (I'm shooting old lenses on a Pro-SD body). So, what are the pictures going to look like?
