Sony A7s Vertical Line Issue
Apologies if this topic has been covered elsewhere but I've been searching far and wide across the web to find someone else who's experiencing this same issue. So far no luck!
About a month ago I bought a refurbished Sony A7s from the Sony outlet. I wanted to retain my Canon glass with the camera so I purchased the Commlite EF - E mount smart adapter after reading some good reviews on this site.
All is working well however when I push my ISO I start to get some weird looking effects that aren't matching up to what others are seeing at even higher ISO's. Green and purple vertical lines appear on the screen and grow into what looks like a posterized 3 colour image (Black, Blue and Green) as you push the ISO even further.
This is particularly evident when set to 120FPS as can be seen in the two screenshots below. I'm using my Canon 24-105mm lens and this seems to happen in both Full Frame and APS-C :-
Is this something I'm doing wrong or is it a fault with the camera / adapter / lens? Any help would be hugely appreciated.
