Originally posted by Wired Makes you wonder why no one can duplicate these small lenses. Every lens is larger than their older film day counter parts... I get that. but so massively larger?
OIS? Probably. Aspherical elements? Maybe. A greater number of elements? Probably. Closer focussing? Don't know.
The OIS would account for much of the increase in diameter, and the addition of a greater number of elements would account for length increases, but I would have though aspherical elements might have decreased the total element count.
As for closer focussing, someone with greater understanding than I have might advise here.
