I am sort of in the same boat as you. I am also very much interested in this lens. I have convinced myself that this is the one that I
want (not need). I know, when does need ever enter into the equation. I am at that wonderful point in life where I can afford just about anything I want (as long as the controller of the checkbook agrees
). But, I don't want to spend the money and find out I don't like it, for any unknown reason. So, in July, my wife and I will be visiting our grandson in WA for a week, and I am renting this lens + the FA 50 f/1.4 from camerarentals.com and I plan to shoot the crap out of both of them. I don't forsee any reason why I would not like both of them, but just want to make sure before I purchase.
