Hi there,

1) Is it normal, that you have to use quite some force to put EF-Mount Lenses on the Speedbooster

2) While I used my Samyang 85 T.1.5 on my Sony FS 700 there were some artifacts when I was wide-open (T 2)
is that a known issue? (Not sure if I had the internal NDs on...)

Cheers

EF mounts lenses are a very tight fit on my speedbooster iv. Whether its a Canon L, Sigma or Tokina lens there are all hard to twist on. They all work well with the A7s though.
 
I've had a problem with infinity focus with the speedbooster and Rokinon lenses. Make sure your infinity is accurate (in the unlikely possibility that this is part of your problem).
