I have had the Panasonic 100-300mm lens for some time. Last year I tested it in comparison with the Olympus 75-300 lens. The Panasonic won hands down at every focal length.

I was curious whether the new Olympus 75-300 II lens would be any better. Son of gun, it is. I tested them with the OM-D on a heavy duty Gitzo carbon fiber tripod and a RRS BH-55 bullhead. Hard to have a more stable platform. Tested the lenses at 100, 200, 250, and 300mm. Lenses produced the same results except at 300mm, where the Olympus seems to be better.

So the good news is that Olympus has produced a better lens. The bad news is that I am compelled to buy it. Sigh.

Thanks for the test. But I am not so sure about the conclusion. Note that a) the new 75-300 is optically identical to the old save for new (and hopefully better) antireflective coatings and b) the two lenses were not focused identically in your test images (focus placed closer to the camera with the Pany 100-300).

May be that is exactly the problem with the 100-300mm : it isn't really able to focus at the long end. I have similar results with mine and it is clearly visible while focusing manually : I need to go just a tad further to be in focus, but I'm a the end of the distance scale already. My lens went to Panasonic support services, but came back with the mention that the lens was "inside of specifications".

BTW : thank you for the test. That was really interesting. Although now I wonder whether I shouldn't exchange my 100-300mm for the new Oly on. : it is lighter and now that I have updated my G3 fo the E-M5 I don't need stabilization anymore.
