What to Compare Before Buying
- Lens fit: This ring is made for the Sigma APO 70-200mm F2.8 II EX DG MACRO HSM lens. Check the exact lens model before ordering.
- Ring size: The stated size is 71 mm, so the lens collar area needs to match that size.
- Tripod thread: The mount uses a 1/4" UNC thread, so confirm your tripod head or plate accepts that connection.
- Material: It is metal, which matters if you prefer a rigid mounting accessory.
What Else You May Need
A compatible tripod or support with a 1/4" connection is needed to make use of the mounting thread.
Before You Decide
Confirm the exact Sigma lens model, the 71 mm size and the 1/4" thread before choosing an offer. If your lens or tripod connection differs, a different ring or adaptor will be needed.
