What to Compare Before Buying
- Exact lens model: This collar is for Tamron 100-400mm f/4.5-6.3 Di VC USD (A035), so the model code matters more than a general lens description.
- Tripod head fit: The base uses a 39 mm Arca-Swiss fit, so compare that with your ball head or clamp.
- Mounting threads: Check whether you need 1/4", 3/8" or both screw hole sizes for your setup.
- Plate length: The stated 90 mm detachable plate may affect how the collar sits on your tripod arrangement.
Compatibility, Size and Fit
The collar is intended for Tamron 100-400mm f/4.5-6.3 Di VC USD (A035) and is specifically stated as not compatible with the Tamron 50-400mm f/4.5-6.3 Di III VXD A067. That makes the exact lens model the key check before purchase.
The bottom plate is described as Arca-Swiss fit at 39 mm, so the tripod head or clamp needs to match that style. If your support system uses a different clamp standard, confirm compatibility before choosing this part.
What Else You May Need
You will need a tripod or ball head that matches the stated Arca-Swiss fit if you want to use the quick release plate function. For a secure setup, also check that your own mounting hardware uses the same thread sizes or clamp format.
Before You Decide
Confirm the exact lens model first, as this ring is made for Tamron 100-400mm f/4.5-6.3 Di VC USD (A035) and not the 50-400mm A067. Then check that your tripod head uses a 39 mm Arca-Swiss fit and that the 1/4" or 3/8" mounting arrangement suits your setup.
