A Monumental and Majestic Work of Epic Proportions by your lowly and humble photographic servant.
Clearly the middle one. Only because your sense of framing wouldn't permit you to put it anywhere else. Besides, it has the most obnoxious focus ring. The one on the left looks like an ashtray.
I would say the one on the right, He is way to cheap to buy a L series lens!!
Awesome. I want one too.
Definitely the one on the right. Left: I dont think they would include a lens-hood on a coffe mug - regardless of its anatomical-correctness. Middle: who would buy a non-L series coffee mug... Kirlin is better than that.
