An Australian website is already giving an estimated price for the 7-14mm f2.8 ($AUS1799)
Ray-I don't know why I had it in my mind that the 300mm would be f2.8. Now I wonder why they made it f4.
Not really. Technically it's still a 300mm focal length lens, it's just that the field of view is equivalent to a 600mm lens. If I were to put a Nikon/Canon 300mm lens with adapter on a m4/3 camera, it would perform in the same way. The real issue is probably with keeping costs down, as a Nikon/Canon f4 lens costs around $1800, but their f2.8 lenses are around $8000.Ray-
Perhaps because although its specified as a "300mm", given that it's an M/43 lens, it really equates to the 35mm equivalent of a 600mm lens! Nikon's own 600 / f4 currently sells for just a butt-hair shy of $10k and weighs in at over 11 lbs! mg:
