Trying out my newly arrived Olympus 75mm f/1.8 lens. From several images at different shutter speeds it appears that the slowest speed I can use for a sharp image is 1/100 of a second on the GH2...but I'll bet I will get better results at 1/150 of a second! Update, next morning: I have decided to return this lens. It's too limited on a non-stabilized body. I also did not like the feel of the very loose focus ring. Not enough resistance.
