Got the sony A7s while back in Hong Kong for vacation, full user experience and review coming soon, be sure to let me know what you would like to know about the camera so i can put it in the review. I was fortunate enough to listen and talk to Den Lennie about the sony a7s, which has helped me greatly in understanding the camera.
This camera has amazing low light capabilities as claimed, some of the shots in this video were pushed to 64000 iso and still produced a usable image, around half of the shots were filmed in Slog-2. Say goodbye to the mushy canon dslr footage, the 1080 xacvs footage is detailed and has a good amount of wiggle room in post.
