Quick Summary
The iShoot metal lens collar tripod mount ring is made for the Tamron 50-400mm f/4.5-6.3 Di III VXD A067. It combines a lens support holder bracket with an Arca-Swiss fit quick release plate dovetail groove, so the mounting style is built into the collar itself.
The collar also uses a 180° quick-lock knob, a solid connection shaft and a thickened ring body. The inner wall is lined with PVC film, and the base includes 1/4" and 3/8" screw holes with stainless-steel anti-slip screws.

What to Compare Before Buying
- Lens compatibility: This ring is made for the Tamron 50-400mm f/4.5-6.3 Di III VXD A067. Check the exact lens model before choosing it.
- Tripod interface: The base has an Arca-Swiss fit dovetail groove. Make sure your head or clamp matches that format.
- Mounting method: The collar also includes 1/4" and 3/8" screw holes. Compare those fixing points with the tripod or support you plan to use.

Compatibility, Size and Fit
This collar is stated to be compatible only with the Tamron 50-400mm f/4.5-6.3 Di III VXD A067 and not other lenses. The Arca-Swiss fit base is relevant if you use an Arca-Swiss style ball head, panoramic head or clamp. For a direct tripod mount, check whether you need the 1/4" or 3/8" fixing point.
Before You Decide
Confirm that your lens is the Tamron 50-400mm f/4.5-6.3 Di III VXD A067. Check that your tripod head or clamp matches the Arca-Swiss fit base, and decide whether you want to use the 1/4" or 3/8" screw holes instead of the quick release groove. If you plan to use the separate IS-3950PRO converter, make sure that part is part of your setup.
