I saw yesterday the rumor that Olympus is going to launch a 40-300mm f/2.8 PRO lens. I got really stoked about it because my dream lens, that Im going to start saving once I buy a OMD-EM1, is the Pany 35-100mm f/2.8. IMO its a must-have lens for any format. The thing comes here in the price. Im not really pleased that the Pany is $1500 brand new (Not even thinking in buying it used) and the more versatily Olympus is going to be, base on the rumor, just $1000 . Should I wait, I have to get the money anyways, for the Oly or go for the trusty Pany?
