In short: A focus puller, or first assistant camera (1st AC), keeps the shot in focus through each take, marks the focus positions and sets the aperture as the director of photography asks. They also set up, test, clean and maintain the camera and lenses, and they report to the camera operator. Most start as camera trainees and work up through the camera department.
A focus puller is the first assistant camera, who keeps the shot in focus and looks after the camera and lenses through the day. They report to the camera operator and manage the camera crew, and they are the person the director of photography trusts to make the lens do what was asked.
What a focus puller does on a shoot day
- Set up and test the camera. Build the camera, fit the lenses and check everything works before the first shot.
- Mark the focus. Measure the distances in rehearsal and mark them on the follow-focus ring or the remote focus unit. The second assistant camera lays the actors' floor marks.
- Pull focus during the take. Move focus smoothly from one subject to another, and hold it when the subject moves.
- Adjust the aperture. Change the stop as the director of photography directs, and select filters when the look calls for them.
- Flag problems. Watch the monitor for soft focus and report it straight away, rather than hoping the take is fine.
- Clean, de-rig and pack. Keep the lenses clean, check the kit at the end of the day and pack the camera safely.
The focus puller also watches the lighting. Shadows and reflections can ruin a take, and the focus puller is often the first to notice.
Who they work with
The focus puller reports to the camera operator and works closely with the director of photography. They also work with the second assistant camera, who handles the clapperboard and camera paperwork, and with grips, especially on tracking and crane shots. Electricians help with flags, and the script supervisor records technical data. Assistant directors and production keep the schedule on track.
Kit and skills
The focus puller usually brings a tape measure and marking tools, often their own wireless follow focus, and works with the production's camera and lenses. The production usually brings its own camera and lenses, so ask us what the room provides before the day.
Skills that matter most:
- Judging focus by eye and by monitor, and knowing when the monitor is lying.
- Working quickly and quietly, with an actor moving toward you.
- Maintaining and cleaning equipment, and recognising a fault before it stops a shoot.
- Communicating clearly with the camera operator and the director of photography.
- Staying calm under pressure and keeping paperwork in order.
How to become a focus puller
ScreenSkills describes a route through the camera department rather than a single entry point:
- Camera trainee. Trainees prepare equipment, help with lens tests, mark actors' positions in rehearsal and keep camera logs.
- Second assistant camera or clapper loader. Experienced trainees take on the clapperboard and battery work, then move towards the focus role.
- Focus puller. The first assistant camera takes responsibility for focus, the camera and the crew.
Trainee places come through ScreenSkills' Trainee Finder and the Guild of British Camera Technicians. A degree is optional. Many people build a portfolio and a showreel, work as a kit runner at an equipment rental company, and meet people at ScreenSkills events.
Do you need one on a small shoot?
- A locked-off interview or a single camera on a tripod: usually not. The operator can pull focus.
- A studio shoot with a fixed frame: not usually, unless the camera moves or the lens is open wide.
- A tracking shot, a crane, a handheld walk-and-talk or a moving subject: yes, a focus puller makes the difference.

Questions we get asked
What does a focus puller do on a film set?
The focus puller keeps the subject sharp by adjusting focus during the take, prepares focus marks, sets apertures as the director of photography directs, and looks after the camera and lenses. They work under the camera operator and manage the camera crew.
How do you become a focus puller in the UK?
Most people start as a camera trainee, then move to second assistant camera or clapper loader before taking the focus pulling role. ScreenSkills and the Guild of British Camera Technicians both run trainee schemes.
Do you need a focus puller on a small shoot?
Not always. A locked-off interview or a simple single-camera shot can be focused by the operator. A focus puller helps when the camera moves, the lens is wide open or the subject moves through the frame.
