Wow! The Olympus Zuiko Digital 35-100mm f2 is in production and the first reviews have just started appearing. Perhaps I'm being a dog of little brain, but how on earth does it work? How on earth does it sustain such a wide aperture throughout the entire range of the zoom? Surely, with 15 odd elements, and varying distances between them, some of those little photons (not quite a wave, not quite particles) are going to bounce off and go astray? I don't understand: it's wizardry. Or alchemy at least. No picture of me today, but a rather nice pigeon and a kindly homeless Frenchman who feeds it on his daily walk, taken with the above lens's considerably cheaper and more portable cousin, the Zuiko Digital 40-150mm f3.5-4.5.
