Hmmh, feels a bit pointless. A massive lens it seems.
Thought so, too. As great as the 50 mm Art is, I always hesitate to put it in my bag for a walk, somehow I feel bound to 35 and 85 if I want to go light. The 24-105 also has M82 filter thread, so I know how massive that thing is. Given the pictures, this new thing is even bigger.
