The beercan is a huge and sharp lens to ow, but a heavy bastard to carry around.
I made all that shots by manual work. I recommend the use of this lens with an LA-EA 2
adapter that will make i AF. The Nex is too light to handle that size and adjusting focus
manually at 70 mm becomes a real sport when you carry it. Also the focusing
and the zoom rings are too lose, they move very easy and focusing is off quiet fast.
