I have a Panasonic G3, with a 20mm/1.7; 14-45, and 100-300. I've been happy with the 20, but not so much with the other two. It's been recommended to me to just use primes to get the most out of the camera. As the price of the Panny 45 is way up there (and touted as a macro), I'm lead to the Olympus 45/1.8 and/or the 75/1.8 lenses. But I'm wondering about the reality of those lenses leaving me with no Image Stabilization - what's the reality of that in day to day shooting? I guess I fear finding out after the purchase that every shot requires an incredibly steady hand or a tripod, with little to no forgiveness. Any experience with that?
