Panasonic 100-300 vs. Olympus 75-300 II lens test
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.
