Lately I have been giving some serious thought to parting with my D3S and assorted lenses and switching to a Sony A7. The things I like the most about my D3S are low light capability and image quality. I do not shoot much video in fact I have never used my D3S for video. There are quite a few different A7's out there and trying to decide which one fits me best is a little overwhelming. My reason for the switch is mainly due to the weight of my current gear. I'm not getting any younger. Any feedback is appreciated.
