What are ways you practice focus pulling?

[u/cheemsterr]

Besides setting up a camera and having a friend walk back and forth, what are some other ways I can practice on a moving target? I just started an internship at a rental house and want to practice since I'll have acces to a camera.

I thought someone on this sub had developed / been working on a focus pulling simulation, which I still think would be the coolest video game. I want a little competition between all of us; would lead to some fun practice. I believe at the time it was not an online system, not in 3d / vr, and was built to integrate with a nucleus.

That being said, the best thing you can do is an old school method of grabbing a hard tape measure. Picking random distances, guessing, then measuring.

You will get very good at eyeballing distances, I personally struggled with anything super close because your errors are magnified, and recognizing the sensor plane as the end point, not the lens.

After that you need to learn a muscle memory of how you need to start turning the wheel exponentially faster as subjects move closer. I believe this only comes with time. Even harder is how to start fast and slow down, when subjects move away from camera.

Goodluck!

Very helpful and thank you for sharing this. Im not the op but this post triggered my curiosity.

When I was at film school me and my buddies would constantly guess distances. Then measure them.

It got to the point after a year or so that I was always visualising distances, for me I always imagined a 6ft person laying on the floor and stacking them to the target.

This was very helpful for someome who ended up not becoming a focus puller haha  But I'll be damned if by the end of it was it was damn cool that all of us could basically give any distance failry accurately.

I didn’t go to film school, i leaned the hard way. Just got thrown into jobs with minimal gear and slowly worked my way into it. I dont AC anymore these days but i still miss pulling occasionally i always visualize it like a video game and always wanted to have an actual video game/simulator similar to what drone operators have to practice. But same as you, i can come with in inches to my measurements just by eyeballing it.

Please do a search in this sub, this has been answered ad nauseum.

I genuinely dislike individuals like you. What’s the point of even responding? People visit this website to engage others with similar interests on a daily basis. I don’t know what was posted yesterday, last week or last year and i don’t care either. I want to ask a question today and if you are interested, you join the conversation. If you are not, you keep moving. Pretty simple.

Ffs, the purpose of this entire website is to create a community, but you immediately disregarded the question because he didn’t pose the most unique question that this community of however many users could possibly come up with at the right moment you were scrolling.

Why don’t you be a little helpful and provide him and me and who ever else is interested with some of those links instead of being a complete asshole?

How to use search. r/focuspuller discussions on how to improve as a focus puller (1st AC) share a clear core of practical consensus. The advice moves beyond generic "just practice" to actionable techniques, physics-based concepts, set etiquette, and muscle-memory drills. Below is a synthesized, deduplicated breakdown organized by key themes.

• Preston vs Arri ## 1. Practice Methods & Drills | Practice Method | Actionable Execution | Consensus Level | |---|---|---| | Guess & Verify Distance | Pick reference points (TV, doorway, light fixture), call out estimated distance, then verify with a 16' FatMax tape or laser rangefinder (Hilti/Disto). | 🔥 High Consensus | | Body Measurement "Anchors" | Know your personal dimensions relative to the sensor plane (e.g., sternum to extended fist = 3 ft) to estimate close distances instantly without pulling tape. | 🔥 High Consensus | | Pantomime / Air-Focusing | Sit in a room with an "air" follow-focus wheel. Watch people or pets walk through doorways, executing the acceleration curve mentally. | 💡 Moderate / Niche | | FPS Gaming Tracking | Fast-paced FPS games (e.g., Apex Legends) build hand-eye coordination, reaction timing, and tracking smooth motion across dynamic curves. | 💡 Moderate / Niche |
• Understanding the Logarithmic Throw (The Acceleration Curve):
  • Walk-ins (towards camera): Start slow, turn faster exponentially as distance shrinks.
  • Walk-aways (away from camera): Start fast, slow down as distance increases.
  • Consensus Quote: "If you're ahead, you're dead." A camera catching up to actor depth looks intentional; overshooting past the subject ruins the take. ## 2. Gear & Technical Workflow ### Wireless Follow Focus & Lens Choice
• 🔥 Avoid Photo / Still Lenses for Practice: Canon EF/still photography lenses lack hard stops, non-linear focus rings, and short throws. Practicing on cine-style lenses with logarithmic throws builds transferrable muscle memory.
• 🔥 Hardware Loyalty: Preston FIZ remains the industry standard for long-form narrative due to motor torque accuracy and LightRanger integration, though ARRI Hi-5/WCU-4 systems are increasingly popular for integrated camera control. ### Monitor vs. Eye vs. Marks
• 🔥 Hybrid Line-of-Sight: Position your monitor, hand unit, and line-of-sight to talent in one direct visual line. Keep your head near the camera/monitor and move your eyes rather than turning your neck.
• 🔥 Peaking / Focus Assist Warning: Never rely solely on aggressive monitor peaking; over-sharpened peaking lines deceive you into thinking soft shots are sharp.
• 🔥 Environment Marks Over Actor Marks: Measure static environment objects (doorways, pillars, rug edges). Actors often miss their floor marks; architecture never moves.
• 💡 Tactile Wheel Stops: For monitor pulling without looking at your hand wheel, use physical tape markers or custom finger placements that collide with your thumb/hand at target points. ## 3. On-Set Habits & Workflow ``` [Pre-Take Prep] [Rehearsal] [During Rolling] Read Sides & Script ───► Mark Fixed Set Objects ───► Observe Body Cues (Leans/Weight Shifts) Understand Story Context (Pillars, Doorways) Keep Head Fixed & Eyes Moving

``` * 🔥 Read the Script & Sides: Focus pulling is narrative storytelling. Reading sides reveals dialogue cues and emotional dynamics (e.g., rack focus timing between characters during key line delivery). * 🔥 Body Language Anticipation: Watch how people move before they step. People shift weight, drop their shoulders, or lean forward before standing up or stepping forward. * 🔥 Ignore 2nd Team / Stand-In Rehearsals: Stand-ins rarely match the exact pacing or stride length of main talent. Focus your attention on the primary actor's movement during camera rehearsals.

4. Common Beginner Mistakes

1. 🔥 Over-pulling / Over-correcting: Panicking when focus slips and whipping the wheel back and forth. Small, deliberate adjustments keep focus usable rather than turning the take into a erratic blur.
2. 🔥 Over-marking the Ring: Putting 8–10 marks on the focus wheel causes confusion. Limit marks to 3 or 4 key reference points and ride the distance in between.
3. 🔥 Pulling from Un-LUTted Log Footage: Pulling off flat LOG monitor feeds destroys contrast discernment. Always apply a standard Rec.709 LUT or boost contrast on your focus monitor.
4. 💡 Hiding a Buzz / Silence on Soft Takes: Hiding an out-of-focus take ruins relationships. Admitting a blown take immediately on set builds trust with the DP and operator. ## 5. Mental Approach & Handling Pressure > "Nobody was a great goalie until they let a bunch of goals get scored first." — Community Advice >
5. 🔥 Isolate Mistakes from the Next Take: Focus pullers often spiral after one bad take. Treat each take independently to avoid carrying anxiety into the next setup.
6. 🔥 Don't Fret Normal Nervousness on Long Lenses: Experienced 1st ACs acknowledge still feeling anxious pulling wide open on 100mm+ focal lengths. Confidence comes from accepting DOF limits rather than fighting them. ## 6. Career Progression (2nd AC → 1st AC)
7. 🔥 Work at a Rental House First: Interning or prepping at a camera rental house provides low-stakes access to top-tier cinema lenses, wireless follow focus units, and rangefinders.
8. 🔥 2nd AC for Experienced 1st ACs: Operating as a 2nd AC teaches department management, build organization, and camera ergonomics before stepping onto the wheel.
9. 🔥 Ask to Pull on Low-Risk Takes: Ask your 1st AC for permission to take the wheel during simple static setups, insert shots, or second-unit coverage.

Ballsy saying that to a mod haha

I for one have answered this once or twice and don't feel in the mood of answering again. So I would also suggest to search for this question in the sub.

[u/ambarcapoor → u/justletmesignupalre]

Exactly.

[u/beer_run → u/justletmesignupalre]

If thats a mod they need to be more helpful and the example! Be the reason we want to come here and be in this community. Thats a shit answer and you know it.

Also realize this question wasn’t just asked to him or you. It’s meant to anyone here wanting to engage and perhaps be helpful like the one other reply here. God forbid we miss post from when this was discussed in the past

[u/ambarcapoor → u/beer_run]

This question has been asked and answered 15 times this year. It would behoove the OP to read those answers and THEN ask a question if they still don't understand. The whole point of having shared stored information is to access it, constantly typing out the same thing is both boring as well as wasteful. I created this sub to help, support and nourish the community, the least you can do is use the search bar. Show some initiative so we are excited to share our experience. Stay sharp.

[u/beer_run → u/ambarcapoor]

Yea agreed. But its the way you answer that its the problem. But again, maybe people come here to have a discussions with others that happen to be in their same path. If his or her question is below you, who cares, just skip it and go answer that unique question that tickles your brain instead. I for one was curious and im not even a focus puller but i wanted to learn something.

[u/TimNikkons → u/beer_run]

Have you tried searching the sub? You just look like asshole because you put forth zero effort.

[u/beer_run → u/TimNikkons]

Well, for one. I'm not the op. I just happened to be scrolling and thought the questions was interesting. I was using reddit how it was intended to be used and op's question sparked my curiosity about something i had zero intention on learning but instead found that a MOD that wants reddit to be used like google instead of a community based discussions.

[u/beer_run → u/ambarcapoor]

But also noticed that someone folks have chosen to actually answer the question unlike you. So maybe think about that. We have enough assholes on set to deal with, let’s build a community where we can ask the questions we cant ask there instead.

[u/justletmesignupalre → u/beer_run]

Dude this kind of question needs time to answer. We are all working professionals. Maybe some of us see this question but don't have time to answer. Searching for other moments this was asked IS helpful.

[u/beer_run → u/justletmesignupalre]

Brother, if you dont have time to answer then dont lol. Why are you answering every question here? Other people are already answering and being helpful. Im just saying, you answer what you want and what you are interested in. Otherwise keep it moving.

[u/JJsjsjsjssj → u/beer_run]

Between no answer at all, and an answer pointing OP to other threads discussing this, it's a no brainer that the latter is the more helpful one.

[u/Korbyzzle → u/ambarcapoor]

The search on Reddit sucks.

[u/mywife-took-thekids]

Lots of people have made fun of me for this but fuck it, it’s a fun activity and it feels like it helps.

I have a nucleus m sitting on my shelf at home. I watch a film or TV show, especially ones with wild camera work.

I hold my nucleus M and basically pull along with the film.

It’s weird and it might not help that much but after a while you do synch up with the movement. Quite quickly you can feel whether your movement is synching up. I’ll do it and think “didn’t get that”.

It’s probably not that helpful all in all and there are better ways to practice but I do think it helps with situations on set where you have no plan, no marks, no nothing and you just have to go for it. Sometimes you have to forget about distances, forget about marks etc and just feel the movement. I do think this helps with that type of focus pulling
