Mainly shot the R with the new 28-70 zoom, and was allowed to use my own memory card and keep the raw files, however am on the road and only have an ipad air with me until tomorrow evening. Files look nice but I suspect the lens has soft-ish edges, will report back after looking at the RAWs on a proper screen tomorrow.
First impressions: camera feels great, seems about same size as E-M1 but a little lighter with respective zooms. Menus and buttons feel clear and intuitive. Shutter is very loud and sounds like it is firing twice, I had to check I wasn't in continuous mode!
