What to Compare Before Buying
- Lens compatibility: This ring is listed for specific Tamron and Sigma lenses only. Match your exact lens model and mount before buying.
- Tripod connection: The ring provides an Arca-compatible dovetail plate and 1/4"-20 and 3/8"-16 thread screw holes. Check which tripod head or clamp you plan to use.
- Mounting format: If you already use Arca-Swiss style support gear, the dovetail plate is the key feature to compare.
- Lens support need: A collar ring is relevant when the lens is long or heavy enough to benefit from tripod support at the lens rather than the camera body.
Compatibility, Size and Fit
This ring is listed for the Tamron 35-150mm F/2-2.8 Di III VXD (A058) Lens for E-mount, and the Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens for Canon EF and Nikon F Mount. It is best to confirm the exact lens model and mount before choosing an offer, because lens collars are model-specific.
Before You Decide
Confirm that your lens matches one of the listed compatible models and mount versions. Check that your tripod head or clamp suits the Arca-compatible dovetail plate or the 1/4"-20 and 3/8"-16 thread screw holes. If your lens is a different version, choose a collar made for that exact model.
