Here is a Moorhen taken with the the new Olympus OM-D E-M5 with a m.Zuiko 75-300, @300mm (600mm equivalent) hand held with sensor shift stabilisation on at ISO 1000:

There isn't any E-M5 RAW support in Lightroom yet so this was exported from Olympus Viewer 2 from the RAW file as a TIFF and imported to Lightroom 4 and post processed there. I did a fair amount of work on this, including some use of the adjustment brush and graduated filter in LR. But I think it has turned out well and shows what the E-M5 can do with the 75-300. This was a hand held shot at ISO 1000, 1/200th shutter speed, f/6.7 (wide open) - the Moorhen was on a shaded area of the canal bank. About 42% of the original frame has been cropped off, leaving about 9.5 megapixels to work with.
