iShoot Lens Collar Compatible with Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR, Lens Tripod Mount Ring Support Bracket Holder, Bottom is ARCA Fit Quick Release Plate for Tripod Ball Head ARCA-Swiss Type

Well made. Easy replacement and securely fits my ARCA style ball head.

I didn't want to spend hundreds on a RRS so I bought the iShoot brand. It's well built and not flimsy. The only thing you don't get is a QD socket, but I added a screw in QD adapter so I can use may shoulder sling.

A major issue for wildlife and sports photographers is the ability to adequately support a heavy telephoto lens whilst maintaining an accurate tracking and focus of the subject.The iShoot collar for the Nikon 200-500 f5.6 lens by allowing you to clamp the camera / lens directly to an Arca Swiss compatible gimbal that completely supports the camera in action allowing you to track the subject easily.Works with a monopod or tripod gimbal.highly recommended

The original got damaged. This is just as sturdy, significantly cheaper and has the added benefit of an integrated standard tripod seat not requiring an add on as the original did. Quicker and more stable to mount on a tripod or gimbal.

It is a good value for the money. Well built. The tolerance is a bit lose yet some how harder to roll from landscape to portrait than the original Nikon bracket. I buy this one for the built in ARCA plate feature.

this is awesome... i bought a used lens and the original collar mount was worn so I started looking for a new one and i ordered this one and turned out to be amazing it holds the lens firm

For a replacement collar foot combo not great. It is sticky and difficult with turning the lens. Just not smooth. Look at other brands like leofoot. I sent the ishoot back and bought a different brand.

I replaced the original Nikon tripod collar because I added a bracket for my gimbal tripod head. This iShoot Lens Collar has the "V" grooves built in. Balances my camera with the shoulder strap I use.
