Treehouse - BMPCC with cheap EF adapter

There is a hotel in a tree in my hometown Västerås, and one under ground, and one under water.
Today as I was in the park a nice newlywed couple from Wales checked into the tree.

I was testing my Blackmagic Pocket Cinema Camera with a dumb EF adapter. It worked great on my 24-105/4 with a fixed aperture of f4. But it was also surprisingly working on my 10-18 IS STM.
It turns out that it refocuses while I zoom so I could focus with the zoom ring, quirky but fun.
But it also lead me to a focus miss that I kept in the video, sorry about that but I think that if we try, we can keep on going  

 

Its the grading. This camera has a black belt in not crushing shadows if you whant to.
