>>3908823I took this at 24mm f/4. Focus was 0.5m. So a 16mm 2.8 at rough vlogging distance will look about like this. The trees in the background are 10-15m away.
Keep in mind the “cinematic” look is a mix of things. Lighting and good color are just as important, if not more than a blurry background. In fact, I'd say this pic is about what you want. Too blurry and it stops looking cinematic, and more like it was shot on a DSLR.
