For the second year I will be photographing the 10k run for SC811. Last year I photographed this event with a Canon SL1 and 15-85 lens. The company was very pleased with the results so they are delighted that I have agreed to do it again. This year I have converted to Olympus m43 and have the e-m5, e-pm2, 17mm 2.8, 25mm 1.8, 45mm 1.8, 14-42 II R and 40-150mm R. I will certainly be purchasing at least one backup battery. I still own the shoulder harness from when I was photographing weddings, so I can easily carry both bodies with lenses attached without fear of dropping anything. I am just in the process of building my kit and only have the bundled flash units. I will be shooting from about 6 - 10 am. I would appreciate any tips, tricks and recommendations offered by the fine people on this site. It is my understanding that I should use single instead of continous autofocus. Thank you for any insight you are able to share.
