Features

Overview: The Sigma APO Tele Converter 2x is a fast and easy way to double the focal length of your lenses.

You will want to contact an Advisor by phone or online chat to discuss compatibility with your current lens. They will be able to pull this adapter and see if it will work. If it does not, then they will also be able to discuss other options with you. [ Jeff  Dec 20, 2013 ]  Staff
