Is there not anything available to electronically focus on film or DSLR cameras? Are the only means of accurately pulling focus on a moving shot to have a focus assist monitor and a focus puller? Sorry...I'm a stupid newbie.

Some consumer/prosumer video cameras have auto focus. You can use a tape measure (or possibly a Lazar distance measure), which is what the top focus pullers use.

The electronic auto focus tends to hunt, which isn't really much use for quality work. Although, I believe it's an option on the new Canon mount RED Scarlet.
