As the presenter Lok Tse suggested, none of this controversy would have arisen had this lens not been marketed as an 'L', but rather as 70-300 f4-5.6 IS II.
It gotta be a joke to call the new 70-300mm f/4-5.6L USM IS a 70-300 f4-5.6 IS II. What "controversy" are they talking about anyway...sighhh. all I know from day 1 following up on this lens are ppl complaining that its too expensive for f/5.6 and too heavy..whatever. Regardless..I find it "satisfaction" wise compared to my 70-200 f/4 and f/2.8 in performance and $s spend. The luv of it most is packing it...no :sweat:
