Really Right Stuff BH-25 Pro – ultra-light ball head with compact B2-mAS screw clamp

BH-25 Pro ball head: ultra-light, compact, and surprisingly robust

If you’re looking for a ball head that hardly shows up in your camera bag but means serious business on the tripod, the Really Right Stuff BH-25 Pro fits the bill quite well. This ultra-light ball head with compact B2-mAS screw clamp is built for everyone who doesn’t want to carry every extra gram on the road and still needs a precise, stable base for their camera.

Weighing only about 0.185 kg and with a height of 6.6 cm, the BH-25 Pro looks almost inconspicuous, yet it delivers a maximum load capacity of up to 4 kg. For mirrorless cameras, lightweight setups, and travel photography this is a very pleasant combination: small, stable, reliable.

Made in the USA: precision from 6061-T6 aluminum and stainless steel

The BH-25 Pro is manufactured in the USA and uses a high-quality mix of 6061-T6 aluminum and stainless steel for its materials. This aluminum is something of a classic in the photo industry: light, stiff, and corrosion-resistant. The heavily stressed parts, such as screws and bearing points, are made of stainless steel, which significantly increases durability in everyday use.

The 25 mm hollow ball moves smoothly and in a controlled manner without jerking. Thanks to the precise machining of the ball and bearing surfaces, you can finely adjust the camera without constantly having to correct it. Especially with longer focal lengths or when you’re working at dusk, this smooth, defined movement really pays off.

Arca-style compatible: flexible quick-release base for your everyday use

The compact B2-mAS screw clamp on the BH-25 Pro is Arca-style compatible and, according to the manufacturer, accepts standard plates with a 38 mm dovetail profile. This makes the ball head an excellent match for existing ARCA setups with compatible quick-release plates, L-brackets, or rails. The screw clamp ensures even, secure clamping of the plate without levers or protruding parts that could snag on something.

Because the clamp is intentionally kept small, the overall design remains very compact. This is especially pleasant when traveling or with minimalist setups, when you carry the tripod on the outside of your backpack or stow it in a tight bag. Despite its small size, the screw clamp provides reliable locking that does not give way even at maximum load.

Thoughtful operation: T-shaped lever with 6 detent positions

A special feature of the BH-25 Pro is the T-shaped control lever. You use this lever to lock and unlock both the ball and the base. The lever is spring-loaded and has six different detent positions, allowing you to lock it in the most suitable position. This is practical when space is tight and you need to reposition the lever briefly without losing clamping force.

This way you can control friction and clamping very directly without having to fiddle with multiple controls. One lever, clear function, quick access. Especially when it’s cold outside or you’re working with gloves, this simple yet well-thought-out operating logic has a noticeably positive effect.

Compact dimensions, strong performance: technical data at a glance

Despite its very small dimensions, the BH-25 Pro offers everything a serious ball head needs. The most important data at a glance:

• Ball diameter: 25 mm hollow ball for precise, controlled movements
• Maximum load capacity: up to 4 kg, ideal for mirrorless cameras and light to medium lenses
• Height: 6.6 cm, making it extremely compact on the tripod
• Base diameter: about 3.3 to 3.4 cm, suitable for many travel tripods
• Weight: only approx. 0.185 kg, perfect for travel photography and outdoor tours
• Tripod thread: 3/8" UNC internal thread for mounting on common tripod heads and shoulders
• Clamp type: screw clamp on the B2-mAS quick-release clamp for secure locking
• Coupling: Arca-style compatible (according to the manufacturer) for 38 mm dovetail plates

Included in the scope of delivery are the ball head itself and the B2-mAS lever quick-release clamp, so you can get started right away, provided you already use compatible ARCA plates.

Ideal for mirrorless and travel photography: small in your bag, big in practice

Modern mirrorless cameras in particular benefit from a ball head like the BH-25 Pro. The combination of a 25 mm ball, 4 kg load capacity, and the very compact design is an excellent match for mirrorless setups with lightweight zooms or prime lenses. Mounted on a lightweight travel tripod, you get a system that you can easily carry with you all day long.

For travel photography this is a real advantage. Whether you’re in the city, on the beach, or somewhere in the mountains: you don’t have to think twice about taking the tripod along, because the overall weight remains manageable. At the same time, you have a precisely operating ball head that holds your camera securely when it counts.

Stable base and secure clamping for daily use

The base of the BH-25 Pro, with a diameter of around 3.4 cm, ensures a stable contact surface on the tripod. In combination with the 3/8" UNC internal thread, mounting on most tripod shoulders is no problem. The 25 mm hollow ball offers a good balance between mobility and stability without the head appearing oversized.

The screw clamp of the B2-mAS mini clamp is deliberately simple but very effective. You tighten the clamping screw and the plate sits firmly. No guesswork, no complicated mechanisms. This is especially pleasant if you frequently switch between portrait and landscape orientation or use different cameras with ARCA-compatible plates.

Practice-oriented design for photographers who are often on the move

In practical use, the BH-25 Pro proves to be an unobtrusive yet reliable companion. It supports your camera securely, can be adjusted quickly, and almost disappears a bit too well in your gear. For anyone using a lightweight travel tripod, this ball head is a very coherent addition because it doesn’t negate the advantages of a compact system.

In short: an ultra-light ball head with a compact B2-mAS screw clamp, Arca-style compatible mount, solid load capacity, and smooth operation, developed especially for mirrorless cameras and travel photography. No show effect, but a small, precise tool that simply works when you need it.
