Oly OMD shooters: what are you using for noise reduction? I recently shot my granddaughter's dance recital with both an OMD-EM5 and a Canon 6D. The 6D files at 12,800 looked considerably better than Oly files at 1600. I know others are shooting m4/3s at 1600, 3200, and even higher ISOs. Am I just too picky, or do they know something I don't know about getting rid of noise?
