Really Right Stuff BEOS-R: Quick-release plate for Canon EOS-R

Really Right Stuff BEOS-R quick-release plate for Canon EOS R

If your Canon EOS R spends more time on the tripod than in your camera bag, you know the situation: you just want to work quickly and precisely, without fiddling around, without wobble. This is exactly where the Really Right Stuff BEOS-R quick-release plate comes in—a precisely fitting camera plate developed specifically for the Canon EOS R that makes your mirrorless Canon noticeably more confident in everyday use.

The BEOS-R is not a universal compromise solution, but a precisely matched plate designed only for the Canon EOS R. As a result, it sits snugly, doesn’t slip, and supports the body exactly where it really makes sense. With a length of 8.8 cm, a depth of 3.8 cm and a height of 1.2 cm, it weighs only 41 g, remaining pleasantly light without feeling delicate or unstable.

Made in the USA, precision from solid stock

The BEOS-R is CNC-milled from solid 6061-T6 aluminum—so it is not cast or somehow “bent into shape,” but machined from a single block. This ensures very high dimensional stability and a clean, flat contact surface on your Canon EOS R. The surface is black anodized (Type II), which makes it more resistant to abrasion and corrosion while keeping the look understated. No bling-bling—more of a tool character for people who know what they’re doing.

The edges are rounded so the plate doesn’t feel sharp in your hand or against your body. Especially when you carry the camera over your shoulder for longer periods, you notice details like this. We’d say: unobtrusively comfortable, but very pleasant in use.

Designed specifically for this camera, full functionality, no hassle

Because the BEOS-R was developed specifically for this camera, the Canon EOS R, all important controls remain accessible. You can easily reach the battery compartment, so you don’t have to remove the plate all the time just to change the battery. The tripod mount is also used properly: the plate is attached with a 1/4" UNC camera screw, which is included. A matching 5/32" hex key is also included so you can mount the plate securely and without play.

Since the BEOS-R is not universal but precisely matched to the contours of the Canon EOS R, it sits stable and without rocking. This is a real advantage, especially with longer focal lengths or during continuous shooting, because the camera doesn’t “work” or twist when you make adjustments.

Arca-style compatible, seamlessly integrable into your tripod setup

The BEOS-R has a 38 mm dovetail clamping profile that, according to the manufacturer, is Arca-style compatible. This means you can use the plate in a wide variety of quick-release clamps without needing special solutions. It fits Wimberley clamps, Arca-style compatible 38 mm quick-release clamps, Really Right Stuff screw and lever clamps, as well as Kirk clamps. In short: if your tripod head or quick-release base is ARCA-compatible, you’re on the safe side with this plate.

You can find more information on ARCA-compatible quick-release systems here. Thanks to this system, you can attach and detach your Canon EOS R extremely quickly without having to realign every time. Especially with changing setups, for example between tripod and gimbal, this is a real time saver.

With QD strap anchor mount, switch flexibly between strap and tripod

The BEOS-R features a QD strap mount, more precisely a QD-compatible strap anchor mount. This allows you to use modern strap systems with QD anchors and detach your Canon EOS R from the strap in a flash and put it on the tripod—or vice versa when things need to move quickly.

To use these QD strap mounts, you need a suitable strap with QD strap anchors. Suitable straps can be found here. Once the setup is dialed in, you can switch very comfortably between carrying and working on the tripod without having to open carabiners or thread loops every time.

Laser-engraved sensor center mark, precise alignment for panoramas

On the top of the BEOS-R there is a laser-engraved sensor center mark. This marking helps you align the camera exactly to the optical axis, which is essential especially for panoramic photography. This allows you to set rotation points precisely and make the transitions between individual images significantly cleaner.

Anyone who frequently shoots panoramas, architecture, or reproducible setups will quickly come to appreciate this small but very helpful marking. It’s one of those details you almost overlook at first, but that makes a noticeable difference in daily use.

Safety stop screw for more security in the quick-release system

The BEOS-R is equipped with a safety stop screw. This screw prevents the camera and plate from accidentally sliding out of the quick-release clamp if the clamp loosens or is not fully closed. The plate can still be moved within the clamp, but it won’t simply slide out completely.

Especially when working at height, on uneven terrain, or when things get hectic, this additional safety layer is very reassuring. You certainly don’t want to lose your camera because of a half turn on the clamp.
