Sony A7S vs Canon 5D Mark III I got a Sony a7s and a Canon 5d Mark iii. Now both the a7 s and the 5d. A combination of photography and video camera, but Sony definitely launched the a7 s to appeal to a larger video audience. While the 5d III is still mostly a Photographer’s camera, etc. At one time it feels a little unfair. Ahead of this comparison because the 5d Mark III is still phenomenal so far. The work of photographers who said there are quite a few videographers using the 5d III for video. That includes me, and for this video for them, unfortunately at the time canon turned on the new video.
