DZOFilm calls focus breathing barely perceptible and close to nil toward 180 mm. Since that claim concerns the telephoto side, a short chart test at 25 mm is worth running before a long rack focus. Measured from the sensor plane, minimum focus is 0.51 m on the wide zoom and 0.89 m on the telephoto, near enough for a dashboard instrument or a hand on the gear lever. The manufacturer also states that image quality holds at high frame rates, so slow-motion inserts sit comfortably beside normal-speed material.

Focus turns through 270°, while iris rotation is 79.55° (25-75mm) or 82.4° (65-180mm). Focus, iris and zoom rings all carry 0.8 MOD gears, placed identically on both zooms, and the focus and iris gears also line up with those of the Arles primes. Swapping one zoom for the other, or for a prime, leaves the motor brackets exactly where the assistant set them. The 95 mm front matches the primes, so one matte-box clamp fits the family, while screw-in filters go on the M86 thread. PL comes fitted at the factory. Alongside the lenses, the hard case holds Y-style lens supports, zoom levers, extension rods, shims and a T6 screwdriver, which lets an in-house technician convert to the separately sold EF mount kit.

Coverage needs stating plainly. The image circle measures 43.5 mm, which is full frame, whereas the Arles primes project 46.5 mm for VistaVision, so a VV-capable body should record in a full-frame area while these zooms are mounted. Mirrorless cameras take them through DZOFilm's Octopus adapters (E, L, Z, RF, X, DX). The Marlin 1.4x converter, in its PL-to-E, L, Z or RF versions, turns the pair into 35-105 mm and 91-252 mm optics at around T3.6–T3.7, about one stop slower, still parfocal, and able to cover selected medium-format sensors. Housings are aluminium alloy, the front element carries a dirt-repellent coating and the barrels resist dust and splashes. Gravel dust at a rally stage or drizzle under a forest canopy is within their tolerance; sustained rain still calls for a cover.

For a production company, the set can anchor a full-frame lens package. Documentary series, commercials, automotive films, drama and independent features can stay on the two zooms through most setups, while a few fast Arles primes, an 18 mm for cramped interiors or a T1.4 lens for night exteriors, take the shots that need more angle or more speed. With colour and gear positions already aligned, those primes can join later without a regrade or a re-rig, and a single case keeps the core of the kit ready for the next booking.
