Essential
Delkin POWER CFexpress 4.0 Type B 512GB · £275
Media at the speed this camera needs for its top recording mode.
Essential
Hähnel HL-A60 Battery (Canon BP-A60) · £180
A spare BP-A pack: the camera takes it directly, and one pack runs the body and a monitor for hours.
Also worth it
Manfrotto Nitrotech 608 + Carbon Fibre Twin GS · £1019
A video tripod with a fluid head rated for this kit, for smooth pans and tilts.
Also worth it
SmallRig mini Follow Focus F40 3010D · £62
A follow focus for geared cine lenses: repeatable focus pulls between marks.
Also worth it
NiSi C5 Matte Box Starter Kit · £169
A matte box: flags stray light off the lens and takes 4×5.65 filters — the cine alternative to screw-in NDs.
Also worth it
Atomos Shogun Classic · £899
A monitor that takes the camera's SDI output: a bigger, brighter picture for focus and framing. At 3,000 nits it stays readable outdoors.
Also worth it
Bright Tangerine LeftField 3 Canon C300 Mk III - Base Kit · £896
A cage made for this body: mounting points for the monitor, mic and handle.
Also worth it
Rode NTG4 Directional Condenser Microphone · £199

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
