Camera bodies, rigs, and accessories are held together with a small, predictable set of screw types — Phillips, flathead, and a handful of hex sizes. A compact bit set covers loose rod clamps, wobbly monitor mounts, and rig hardware that works itself free over a long day. A quality multi-tool backs it up for anything the bit set doesn’t cover.

Scotch tape covers follow-focus rings without leaving residue when marks change scene to scene. Colored spike tape marks actor positions on the floor without confusing them with other departments’ marks. Chalk sticks mark focus points directly on the ground for quick, disposable reference. All three do a version of the same job — marking a position — for different surfaces and durations.

The slate is how editorial finds and syncs every single take, which makes it one of the least optional items in the bag despite how simple it looks. A basic acrylic clapperboard with a smart clap stick works for most productions; digital slates that display running timecode are increasingly standard on anything shooting double-system sound.

Accurate focus pulling starts with an accurate distance measurement, not a guess. A cloth tape measure is the traditional, always-reliable option for measuring from the sensor plane to the subject. A laser rangefinder speeds this up significantly on setups where physically walking a tape to the subject is slow or impossible, though it needs a reflective or matte surface to read accurately.

Handling front and rear lens elements, filters, and sensitive optics with bare hands risks fingerprints and skin oils that are a genuine pain to clean off fully. A pair of clean cotton gloves, swapped out when they get dirty, keeps optics fingerprint-free during lens changes and filter swaps without slowing anything down.

Dust and smudges on front elements happen constantly during exterior work and fast lens changes. A rocket blower clears loose dust without touching the glass; lens tissue or Kimwipes paired with cleaning fluid handle actual smudges without scratching coatings. This is a different (and gentler) kit than what’s used for sensor cleaning, which should stay a separate, more careful process.

Carrying a small sample set of common diffusion and ND filters lets a DP or director make a decision on set rather than waiting for a rental house run. This doesn’t replace a full matte box filter kit for the actual shoot, but it covers quick tests and last-minute creative changes without stopping production.

Small hardware solves small problems fast: a wooden clothespin holds a cable out of frame, a cable tie manages a mess of loose wire on a rig, an adjustable clamp secures a monitor or a flag in a pinch. None of this is glamorous, but it’s used constantly, and being the person with a spare clamp when one’s needed builds trust fast.
