Really Right Stuff B22 - universal lens plate 56mm with 3/8" screw

Really Right Stuff B22, universal lens plate 56 mm with 3/8" screw for photo and video use

Sometimes it’s just one small part that suddenly makes your setup feel truly complete. The Really Right Stuff B22 universal lens plate with a length of 56 mm falls exactly into this category: inconspicuous at first glance, but in everyday use almost indispensable when you want to mount lenses, camera bodies or a spotting scope with a 3/8" thread securely and with repeatable precision on your tripod.

The B22 is a compact, precisely milled lens plate made of robust 6061-T6 aluminum, black anodized for a durable surface. With its 5.6 cm profile length on the underside and a width of 4.6 cm, it offers a stable contact area while remaining pleasantly handy and lightweight. Just 51 g that you practically don’t notice in your backpack, but very much do on the camera.

On the top side there is a longitudinally adjustable 3/8"-16 UNC photo thread screw. This allows you to position the plate exactly at the center of gravity of your lens or spotting scope so that the whole setup is properly balanced on the tripod head. In addition, there is an eccentrically positioned 1/4" threaded hole on the underside, giving you further mounting options, for example for accessories or alternative attachments. An integrated anti-twist stop helps prevent your lens or body from rotating unnoticed on the plate.

Arca-style compatible, precisely matched for 38 mm quick-release clamps

The dovetail clamping profile of the Really Right Stuff B22 is Arca-style compatible and, according to the manufacturer, specifically designed for 38 mm quick-release clamps. If you already use an ARCA compatible ball head, video head or rail, this plate integrates seamlessly into your existing system.

This makes your lens or spotting scope with a 3/8" thread compatible with the 38 mm dovetail quick-release standard in no time. You simply clamp the plate into a suitable Arca-style compatible 38 mm quick-release clamp, tighten it, and you’re done. No fiddling, no improvising with wobbly adapters. We’d call it a clean, professional solution, especially if you often switch between tripod, gimbal and perhaps also a slider.

With QD strap socket, quickly from tripod to strap

A small but very practical detail: the B22 has a QD strap socket, more precisely a QD compatible socket into which you can clip a suitable QD strap anchor. This lets you switch very quickly from tripod use to carrying on a strap without having to re-screw anything each time.

To use this QD strap socket you need a strap with QD strap anchors. You can find suitable straps here, for example: Strap with QD strap anchors. If you travel a lot, for example on trips, assignments or long hikes with a spotting scope, this option is often significantly more comfortable than a classic camera strap that’s constantly getting in the way.

Made in the USA, precise manufacturing and durable materials

The Really Right Stuff B22 universal lens plate is made in the USA, and you can clearly see that in the workmanship. The 6061-T6 aluminum is precisely CNC-milled and then black anodized. This finish creates a hard, durable surface that doesn’t immediately get scratched in daily use if the plate scrapes along a rock or other gear in your case.

Our experience with such plates is that the difference between cheap no-name products and cleanly manufactured parts often only becomes apparent after a few months. The B22 remains dimensionally stable, the edges of the dovetail profile don’t wear down quickly, and the screw threads retain their precise fit. Especially if you use your gear intensively, this quality pays off in the long run.

Universally usable, from Hasselblad body to spotting scope with 3/8" thread

The B22 is designed as a universal lens plate and can be used on a wide variety of devices. It is suitable, for example, for Hasselblad bodies with a 3/8" thread, but equally for other cameras and lenses with the corresponding threaded socket. A spotting scope with a 3/8" thread can also be mounted securely on an ARCA compatible tripod head with it.

Thanks to the adjustable 3/8"-16 UNC screw you can flexibly adapt the position of the plate so that the center of gravity of your setup lies as close as possible above the center of the quick-release clamp. This reduces the tendency to tip and makes panning smoother, which is particularly pleasant with telephoto lenses or spotting scopes. In combination with the anti-twist stop, you get a secure fit that doesn’t require constant readjustment even with frequent repositioning, but simply remains reliably in place.
