It seems as if Olympus will delay the 300mmf4 Pro lens until 2016 to add stabilization to it. I guess that gives the lens a better chance to be sold to a Panasonic body owner. It also begs the question will Olympus bodies in the future take full advantage of both IBIS and lens stabilization. But pushing the 300 Pro into 2016 also means it will be facing the announced 100-400 made by Zeiss. As a wildlife photographer, if Panny/Zeiss can put off that lens for a decent cost, I won't wait in line for the 300mm. Olympus should be doing a 150-400 F4 Pro instead.
