I love shooting birds. I shot tons with my Panasonic IS 300mm and it works great. I use the GH2 Ex.Tele. to reach in even further for video. Anyway, is there a technical reason why Oly and Pana don't make a 400mm IS lens for the Micro 4/3 system? I do have a manual 400mm FD Vivitar lens. I guess that if most or all of the coming GH cams start to have IBIS then I could use any 400, 500 or 600mm legacy class with the cam's IBIS to get that extra reach.
