RossChang said:I think the Nikon Trinity lenses are the 17-35 F2.8, 28-70 F2.8 and the 80-200 F2.8...
the so-called canon trinity would be 16-35mm/f2.8L, 24-70mm/f2.8L and the 70-200mm/f2.8L IS USM (or the non-IS). this combi will set u back, oh, $5k? :sweat:
wat i would call a 'duo-nity' is the 17-40mm/f4L and 70-200mm/f4L. most people will have this combi, and in fact this is the recommended combi for travelling as stated in the canon lens book.
there are other variations to this theme for prime lens. but, trust me... u dun wanna go there... :bsmilie:
