Sony A7 - 50mm lens tests

I keep coming up with small tests to compare the lens l own. I decided to run this test, all at 50mm, Manual focus since my Minolta lens is a MF lens.
I tested using my Minolta Rokkor F2 lens at iso 800,400 F11 then F5.6 iso 200
Then l tested my kit lens 28-70mm set at 50mm using the same settings as above.
Finally l tested using my Sony F1.8 50mm prime lens.
