This of course explains why the Oly wide zooms so outperform the competition (incl. Canon L), in my experience. Oly started this with the E-10 ZLR at least 6 years ago. I suspect Leica's 4/3 designs will do the same, and also expect that Leica is taking the same tack with regards to the new M lens designs they have said are in the works. For the reasons described below the difference is not as important with telephoto lenses. Will Who seems to be posting a lot this morning.
