Should Lumix users buy the Olympus 75mm lens?

I know that portraits are better a little soft but I was testing for sharpness. I'm not sure why flash would make a difference (once focus is made) - it's still 1/60. The lens might do better - 1/60 just happened to be the shutter speed on the ones I have handy; I've only had the lens a short time and haven't really used it. I will thoroughly test the lens in a few days when I visit Seoul, visit friends there with a new daughter, and go to the DMZ.
