Well, as the saying goes, "whatever keeps the kid occupied". Better than beating the crap out of the living things in real life, I'd say.
Anyhoo, I forgot to say that the lens we are discussing (are we not?) looks mighty fine. I like the way the Fuji system looks (but then again, the Sony FE system is also darn sexy by now). I'm thinking that I should've considered something like the X-T1 and the 16/1.4 instead of spending untold amount of cash on the Canon 24/1.4 L... which even isn't as wide on APS-H. Tell us Klaus... is there a chance we might eventually see the 16/1.4 dragged through your testing lab?
