I really need a solution for the 1/160 maximum flash sync speed limitation of my GF1 and GH1. There is simply no getting around it. Even with a 3 stop B+W ND filter that I have, the largest aperture that I can use is about f/4.47 (calculated from the Sunny 16 rule), which is not large enough for my purposes. Using a 6-stop ND filter is a possibility but looks too drastic and will limit my ability to move in and out of shadowy areas during daylight shooting. So I'm thinking of getting an Oly for the sole purpose of obtaining a higher sync speed during daylight shooting, unless I can find a Panny soliution. Do newer Pannys have a higher sync speed? I've also read somewhere that Panny will eventually introduce a micro four thirds with an electronic shutter. Is that on the horizon?
