⚡ At a Glance
- • Mounting Stability: Concave-convex inner wall matches the lens contour for a close grip while the Arca-Swiss style plate secures the setup to compatible heads
- • Best for: Photographers using the Canon RF 100-500mm f/4.5-7.1L IS USM who need quick tripod or monopod attachment
- • Not ideal for: Owners of other lens models, since compatibility is limited to the specified Canon RF 100-500mm lens
Metal tripod collar designed specifically for the Canon RF 100-500mm f/4.5-7.1L IS USM, incorporating a 60mm Arca-style quick release plate. Inner plastic composite film protects the lens surface while allowing free rotation similar to the original tripod ring.
Quick, secure mounting – with a 60mm Arca-fit quick release plate
A 60mm long Arca-style quick release plate is integrated into the collar base and matches Arca-Swiss 39mm fit tripod ball heads, panoramic heads and clamps. The plate is built into the collar rather than being a separate add-on.
Faster, more reliable transitions between tripod and monopod heads, reducing handling time when moving between shooting positions.
Lens-safe clamping and free rotation – thanks to concave-convex lining and plastic composite film
The inner wall has an irregular concave-convex profile that closely follows the lens barrel, with a plastic composite film at contact points to prevent abrasion when installed correctly.
Firm grip without scratching the lens surface, while allowing smooth 360-degree rotation for quick reframing and panoramic work.
Flexible attachment options – with 1/4" and 3/8" screw holes plus anti-slip stainless-steel screws
The support base contains both 1/4" and 3/8" threaded holes and includes stainless-steel anti-slip screws for direct fixing to tripods or monopods. The collar also accepts a clamp mount converter IS-3950PRO sold separately for different head interfaces.
Ability to fix the lens directly to a variety of supports and to adapt to Manfrotto-style hydraulic heads using the available converter.
