Haoge LMR-RF150 Lens Collar Tripod Mount Ring for Canon RF 100-500mm

In this review the Haoge LMR-RF150 is evaluated as a dedicated tripod mount ring for the Canon RF 100-500mm F4.5-7.1 L IS USM. The bottom line: this ring is for photographers who need a sturdy, Arca-compatible collar to improve balance and speed of setup while shooting with the RF 100-500mm. The single biggest reason to buy is its built-in Arca-type dovetail and quick release plate design, which lets you attach the lens directly to Arca-style heads or clamps and eliminates an extra adapter on many rigs.

Key Features

• Arca-compatible dovetail: Provides direct mounting to Ball Heads, Clamps, or Panorama Heads that use the Arca-Swiss standard, speeding setup and ensuring solid clamping.
• Built-in quick release plate: The integrated Arca-type plate removes the need for a separate adapter and lets photographers switch between tripod and hand-held setups faster.
• Reserved screw holes: The 1/4" and 3/8" screw holes on the base allow direct attachment to a tripod or plate for increased versatility in the field.
• Protective inner flannel: A flannel lining on the inner ring cushions the lens barrel, reducing abrasion and protecting the lens finish while clamped.
• Lightweight anodized aluminum: CNC-machined aluminum keeps the ring light while remaining rigid, so it improves balance without adding excessive bulk.
• Built-in strap hole: A strap attachment point makes it easier to carry the lens and collar together when moving between locations.

Who It's For

The LMR-RF150 is aimed at wildlife and sports photographers who use the Canon RF 100-500mm and need a reliable tripod mounting solution that integrates with Arca-style heads and clamps. It is also useful for landscape shooters who work with heavy telephoto setups and need improved balance and a quick way to attach the lens to a tripod.

It is less relevant for photographers who do not own the RF 100-500mm lens or who prefer to use the lens with the original manufacturer collar and foot. If you need multifunction rotation features beyond a basic collar or prefer a collar with an integrated rotating foot for extensive panning, you may want a different model.

Pros & Cons

Cons

• Size received mixed feedback from customers, so those expecting a larger collar might find it smaller than some original collars.
