I have a Sony A7RII and as many of you may already know Sony has decided for some arbitrary reason that they are going to provide us with two aspect ratios: 16:9 and 3:2. I am trying to find a way to film in 4:5 and was wondering if there are any DIY solutions for artificially creating this aspect ratio either in real life or on my viewfinder so I can go in afterwards and crop as needed. Even teh fucking RX100 has at least 1:1 but for some reason the A7Rs don't get it. Wat do?
