Canon RF-S7.8mm f/4 STM Dual

The RF-S7.8mm f/4 STM Dual lens adopts a straight-type lens design, omitting the use of a prism to achieve a more compact design. This prism-less design helps keep the lens weight at approximately 131g, making it highly portable and enabling ease of use in capturing immersive 3D content with optimal balance and functionality.

Stepping Motor (STM)

The dual-lens autofocus (AF) mechanism of the gear-type stepping motor (STM) enables precise, quiet and synchronous focus control of the left and right lenses, which is well-suited for video recording.

Screw-type Filters

With a Neutral Density (ND) filter, you can capture stunning wide-aperture shots even in bright daylight. The RF-S7.8mm f/4 STM Dual supports a 58mm screw-on filter, ensuring effortless control over exposure in outdoor settings.

Focus Differential

The RF-S7.8mm f/4 STM Dual has an actuator that can drive only the right lens independently. This enables the relative focus of the left and right lens to be adjusted using tge left-right focus difference adjustment mode switch and the focusing/control ring.

UD Lenses

This lens uses two Ultra-Low Dispersion (UD) lens elements with low refraction and low dispersion, reducing axial and magnetic chromatic aberrations to deliver high quality 3D visuals.

3D Realism Made Easy

When paired with EOS R7, the RF-S7.8mm f/4 STM Dual lens offers a 63° angle of view for an up-close, natural perspective. In addition to that, its ability to focus at a minimum distance of 15cm makes it ideal for capturing stunning 3D visuals. Positioning your subject between 15 and 50cm maximises the 3D realism, drawing viewers into an immersive scene that feels lifelike and detailed.

A More Efficient Workflow

The RF-S7.8mm f/4 STM Dual enables recording on a single camera with one CMOS image sensor, thereby eliminating certain stages from the workflow that were previously necessary with a two-camera system, such as aligning the positions and synchronising the settings of the left and right cameras before the shoot, or the need to stitch images in post-production.

Single-Sensor Recording

When using the RF-S7.8mm f/4 STM Dual with the EOS R7 mirrorless camera, you can make use of the camera's recording features to produce lifelike 3D 4K footage using just one camera. This eliminates the need to worry about post-processing footage from different cameras.

Two Cameras No Longer Required

Conventional VR recording requires aligning two cameras and syncing camera positions, with additional processes like colour matching and stitching required after shooting. The RF-S7.8mm f/4 STM Dual and EOS R7 have a single-sensor recording capability, eliminating such hassles.

EOS VR Utility

• A computer software application that lets users convert images into equirectangular projections (a standard VR image format) and perform simple editing on them.
• Supports toggling between images/footage shot by the left and right lenses. Also supports toggling between circular fisheye and equirectangular displays.
• Supports image straightening/parallax correction for compatible lenses
• Supports playback and basic cutting of 180-degree VR images on computer monitors.
• Videos recorded in 8K can be converted and saved in a different size, file specification, or format
• LUTs (Lookup Tables) can be applied to videos recorded in Canon Log mode.
• Supports output to DPX (Digital Picture Exchange) and Apple ProRes for NLE (non-linear editing) purposes.
