Just on problem to report, the oly Ib software for editing and firmware update does not seem to work for firmware update pc, and their master 2 does not work for mac and pc. I call oly reported the problem. The tech could not resolve the issue but sent my case to tier II support. And the sent me a stand alone firmware update link. Downloaded the software, and problem solve. I am actually glad I got the stand alone updater. As I would not use the Oly software to edit as I use aperture 3 so it takes up less space on my hard drive. Also the Ib software in not mac compatible yet. A newer version is slate to work with Mac.
I must said the Oly was a pleasure to deal with and the tech support guys are great and friendly.
Also it seem the ver 1 that come with the oly epl-1 do not need a firmware update to the 1.1 that is available for the 14-42mm lens. It seems the epl-1 kit lens has a L designator, as is slightly different from the older model. So the 1.0 firmware on them is up to date. Oly tier II said they will get back to me to confirm this info. So I will keep you all posted.
