Using RAW and a decent raw converter, the high iso performance is so much better than my old FZ18 that the f5.6 at the long end is no problem even in tropical forest. The 100-400 is only 1/2 stop slower at the longest end and the up to date cameras have improved at least one stop over my GH2. By now, what we are all waiting for is a really good tracking performance for BIF in a m4/3 camera. The em1-ii and the promised GH5 might have that kind of tracking (either 1 or both). Of the other pana cameras, I would personally at the moment lean G80/81/85 and not GX8 though the first of these two still are not in the hands of real users. Niels</blockquote>
