Canon 550D & Soviet lenses (1080p)

All footage was shot handheld, using a 1980-s soviet lenses (MIR 1V, Helios 44-2, Industar 50U to name few). As you can see, I am having some difficulties focusing in on the subjects, especially when some of them like to move around, and because 90% of the time the aperture was full wide open (), the focus shifted back and forwards very fast.. Stabilization was another huge issue, as all of it was handheld, I had to support the camera with one hand, the other hand was used to modify the focus
