As I thought, thanks. I would also like to know if anyone has tried this Canon EF adapter, the only thing that worries me is the built-in aperture (I don't know if it effects the image or not): http://www.amazon.com/Fotodiox-EOSa-NX-Apt-DeClk-Adapter--Clicked-Samsung/dp/B00T0QVITM/

I know that A7s and NX1 have different looks, but is it doable matching their colors? I will use same lenses on both (Canon L series 24-70 and 80-200 with adapters). I'd appreciate any suggestions.
