Total disaster while trying to document a surprise party for a friends with EM-5 and 12-35. The photo below is one of the better ones that I got. Did not want to use the flash. Did not do any better with the sequential mode either. E-M5    LUMIX G VARIO 12-35/F2.8    35mm    f/2.8    1/2s    ISO 500 Any suggestion?
