Quote:100-400 is no Nikon offer. 100-300 or 200-500. But a lot of other manufacturers are at home with 100-400. I don't want to knw how light this triple set with a body wil be, and all for FF...Can't be even the same weight as a comparable DSLR setup, the Sony 12-24 alone is half the weight of the Sigma, and the body too (give or take). If I had been starting from scratch with a Sony, I would've gone that route.feeling a tiny bit envy.
(Nikon doesn't have a 100-400 but they have a relatively new 80-400, innit... and the non-OEM 100-400s have been sprouting like mushrooms lately).
