I have a GH3 on order, but until then I've been flying with 5DM2 and 16-35mm f2.8 lens without IS. I've been testing gains, changing isolators, etc and I'm still not happy with the results. It's mostly the smaller jittery type movements that I can't seem to smooth out. I've read almost every thread on the subject and tried most things suggested. I know the Sony CX760 IS is a treasure and I have a lot of experience with the GH2 IS and in the future I will fly with IS. However I was curious if anyone here thinks it's possible to get buttery footage without IS in camera or on lens.
