vintage lenses on a modern camera

Hello there,
recently my grandfather gave me his 40 year old Minolta lenses that i can put them on my A7r II. I doing photography about a year so I wanted to share some footage for feedback. Its not that sharp but i really like that BOKEH there (55mm f1.7)

btw these lenses sell for arround 80$ on ebay and they´re totally worth it!
