Now that the 100-400 lens is out, what do you think should be the next Panasonic-Leica lens? I recently added the 15mm f/1.7 to the 25mm f/1.4, and I really like the new design language on the 15. I would hope that they update the 25 to include that, and maybe be a bit thinner like the 15. I'd also like to see a m4/3 optimized 50mm f/2 Summicron in the same style (and hopefully in the same price bracket and not way up there like the Nocticron). What do you think?
