Q: 4. I have not been able to achieve infinity focus with this speedbooster on my black magic cinema camera 4K. I tried putting vintage takumar lenses onto the booster but the focal distance is reduced to 10 feet as opposed to 30 feet which is what it should be. What can I do about this?

A: Typically it is best to adapt directly from the Camera mount to the lens mount. It sounds like you are adapting an adapted lens which often creates issues (especially when speed boosters are involved).
