I shoot family photos and my kid's baseball on my GH3. I've been using the Panny 45-200mm and getting decent results. I'm really interested in the Oly 75mm, but the lack of OIS is concerning me. If I'm shooting handheld, on the sideline of a baseball game, will it be possible to get steady shots? I'll be in S mode, at 1/250 to 1/400s shutter speed.
