I know one of the lenses that will be announced with the new anniversary camera.....it's the replacement for the 28-70 2.8. I have a very trusted and reliable source that tells me that the new lens will be a 24-70 and we may see it around September. Stocks of the old 28-70 are pretty much exhaused and dealers have not been able to order new production for several months, of course the new lens will be even more expensive so it's hard to say how that will affect prices on the used market. I would expect a lot of trade-ins though. So a word to the wise, if you were planning a 28-70 in your future and your pockets are deep it might be worth some patience to see the new offering.
