If you've ever tried changing focus between subjects while shooting a video with your DSLR, you'll know that auto-focus will often leave you with a stuttering and noisy clip, while using your hand on the lens in manual focus can be tricky. Follow focus systems try to make this easier and better by adding a handle to change focus smoothly, and marker points to move between. The newly-launched FocusMaker is the latest example, which promises the fastest and most accurate focusing of any affordable rack focus system.
