Canon 6D - first test face to face with canon 60D

I just had my new canon 6d. As first test i put togheter with my old canon 60d, only to see how differently it uses the noise reductions. So i decided to use extreme iso starting from 2500 till 12800 (only for 6d). Lights are from a window (4400°K) plus two lamps at 3200°K. The cameras are setted to 3600°K. exposure: 1/50s + f.3.5 to f.6.3 picture style: neutral ( +4 0 -1 +1 ) lenses used: Zeiss Planar 50mm with 60d / Samyang 85mm with 6D no color correction
