Quote:Are they too big? If you want a well corrected lens with more elements in it than the periodic table, it isn't going to be the most compact. If you want small, there will be tradeoffs elsewhere.Indeed, very true. There are of course some lenses that are big, yet are not really outstanding in their type (that Nikkor 17-55mm f2.8 at the long end comes to mind), but the rest in that list are good examples of how new optical designs that try to push IQ boundaries just are bigger than older ones.
