craig nelson 4 Posted March 2, 2017 (edited) Hi Could anyone assist with the getting me the internal diameter of their zoom ring for this lens, alternatively give me the external diameter of the actual zoom ring on the lens. I'm looking to grab a new tokina 11-20mm and I need to establish if the the 11-16 rings will drive the 11-20. I have an email from tokina stating the external zoom ring diameter on the 11-20mm lens is 74.3mm. I can make my own for the 11-20 but it's easier justly to grab an off the shelf if it will work. If anyone could assist, be much obliged. Thanks Craig Edited March 2, 2017 by craig nelson Share this post Link to post Share on other sites
