Camera Configuration

This housing fits the Canon R3 in it’s standard form.



CNC machined from a single piece of billet aluminium then anodised and painted. All buttons and hardware are 316 stainless steel, providing superior corrosion resistance.

Being an aluminium housing it acts as a giant heat sink to assist in managing overheating of the camera compared with a plastic housing like our competitors. It by no means overcomes the overheating issues of the R5 camera, however will manage heat better than a plastic housing.

The housing features 2 quick release clips for closure. The clips are a two stage opening to prevent accidental opening.



The R3 housing utilises our ‘STANDARD’ port system which fits lenses up to 105mm diameter.

The front element in our ports is replaceable in less than 30 seconds by simply unscrewing the locking ring and dropping in a replacement acrylic screen we offer for purchase. So no more spending hours buffing scratched ports!

Note, our STANDARD port reference chart is not applicable to this housing who using EF lenses.

If you are using EF adapter lenses with a basic flat port, you will need to allow for the adapter in any length measurements.

For example, a Canon 24mm f1.4ii measures in at 87mm from the EF mount to the front of the lens.

The RF-EF adapter adds 24mm to the length, so the total length is 111mm, so you would need the S-120 flat port.

However, when using the EF-RF adapter, the housing is compatible with our zoom and focus control ports designed for our RED and BMPCC4K/6K housings. As they share the same focal plane distance measurement. So if you already own one of our RED or BMPCC4K/6K housings, and have ports with focus and zoom control then they will work with the R3 housing.
