Incorporating a 77mm diameter filter thread allows you to mount it on a lens with a 77mm filter thread to achieve close focus. Diopter features highly corrected glass elements with anti-reflective multi-coating for sharp edge-to-edge images. Using this diopter will bring your lens's infinite focus closer. The filter threads are on both the front and back of the adapter, allowing you to stack multiple diopters. Note: Using multiple diopotors may cause vignetting of your image when used with some lenses. ProductSiteLaunchDate : 2024-04-14T03:31:56.552Z
