SmallHD has introduced camera control functionality for Canon Cinema EOS cameras through a $400 USD software license. The system enables real-time configuration of the C70, C80, C300 Mark III, C400, and C500 Mark II directly from compatible SmallHD monitors, allowing operators to adjust shutter speed, aperture, ISO, ND filtration, codec selection, and record triggering through the PageOS platform. Let’s dive into SmallHD Canon camera control.

SmallHD’s Canon integration joins existing camera control protocols for ARRI, RED, and Sony VENICE cameras. The system supports both hardwired Ethernet and WiFi connectivity depending on camera model, with touch-to-focus capability and full access to Canon’s deep menu system.

Monitor interface and workflow

The camera control interface anchors to every page within PageOS, maintaining persistent access to critical parameters. Operators can adjust settings through touchscreen interaction, physical joystick navigation, or the customizable rotary encoder knobs found on monitors like the Ultra 10.

Current camera settings display in a compact overlay that expands when selected. Shutter angle, ISO, ND filtration (adjustable in two-stop increments up to six stops), color profile selection, and white balance controls occupy dedicated sections. Users can slide through values or tap individual parameters for granular adjustment including Kelvin temperature control.

Touch-to-focus works with Canon RF and EF lenses that support autofocus communication. Beyond quick-access parameters, the system provides navigation through Canon’s complete camera menu structure using either the monitor’s joystick or on-screen directional controls.

Collage mode scales up the camera control interface while maintaining access to SmallHD’s monitoring tools. The expanded view displays run/stop control prominently, along with time code and audio level meters. Monitors with programmable dials can assign specific camera functions to rotary encoders, including ND filter control, ISO adjustment, shutter angle, white balance, frame rate, and iris control for compatible lenses.

Compatible monitors

Canon camera control functions across SmallHD’s current monitor range: Cine 5, Ultra 5 series, Cine 7 lineup, Ultra 7 variants, Ultra 10 models, Cine 13/18/24 production monitors, Vision 17/24, OLED 22/27, and Quantum 27/32 displays. Connection methods vary by product line and may require specific adapters.

Connection requirements

The C70 requires a USB-C to Ethernet adapter regardless of connection method since the camera lacks a dedicated Ethernet port. SmallHD specifically recommends the Belkin USB-C to Gigabit Ethernet Adapter after compatibility testing.

For hardwired connections to the C300 Mark III and C500 Mark II, operators need Canon’s EU-V1, EU-V2, or EU-V3 Expansion Unit ($2,219 USD for EU-V3), which provides the Ethernet port. The C400 and C80 feature integrated Ethernet ports, eliminating this requirement and allowing direct connection through standard Ethernet cables.

For WiFi connectivity on the C300 Mark III and C500 Mark II, the Canon WFT-E9A Wireless File Transmitter ($730 USD) provides wireless capability. WiFi connections with SmallHD’s 5-inch or 7-inch monitors require a third-party USB WiFi adapter plus appropriate connection cables. The Cine 7 requires a Micro USB to 5-pin adapter (ACC-C7T-USB-ADP), while the C80 needs the CBL-DAT-LEMO-USB-6 adapter. Larger 4K production monitors include USB connectivity that directly accommodates third-party WiFi adapters.

Activation and limitations of SmallHD Canon camera control

SmallHD requires monitors to run the latest firmware before activating Canon camera control. License activation uses a web-based system at activate.smallhd.com where operators enter their activation code, monitor token, and serial number to receive a license key. Once registered to a specific monitor, camera control licenses cannot be removed or transferred to different displays.

Canon’s camera control protocol does not support playback functionality while camera control is active, requiring operators to disconnect or disable camera control to review recorded footage. Touch-to-focus requires compatible lenses with electronic autofocus communication, and iris control only functions with lenses that communicate aperture data to the camera body.

The SmallHD Canon Camera Control retails for $400 USD as a digital download, with connection hardware ranging from simple Ethernet cables for the C80 and C400 to Canon’s $730 WFT-E9A wireless transmitter or $2,219 EU-V3 expansion unit for the C300 Mark III and C500 Mark II.
