حلقة تثبيت الحامل ثلاثي Canon B II (W) - مستعمل

The locking mechanism is solid and the ring attaches without any wobble, even with my heavy 70-200mm f/2.8L IS II mounted. It's clearly a used piece but the finish has held up well, and it makes balancing on my tripod head effortless.

The mounting ring fits my 70-200mm f/2.8L IS II perfectly, locking in securely with no wobble. It’s a used part but looks practically new, and I appreciate the sturdy metal build for long shoots.

I've been using this ring with my 100-400mm lens for birding, and the quick-release plate fits my ball head perfectly—no wobble at all. It's a solid, used piece that works like new for half the price of a new one.
