Additional Information If your specific adapter size isn’t listed above, additional sizes may be available through Amazon or other online retailers. EXAMPLE: Let's say you have the popular Canon 50mm f/1.4 lens. The filter thread specifications read 72mm. Our Prism Lens FX Filters are not currently offer in a 72mm. Luckily, we have a 72-77mm Step-up ring. You simply screw in the step-up ring to the front of the lens, and you are set. Now you can screw any of our PLFX 77mm FX Filters on top of your 72mm lens. The step-up ring simply increased your lens diameter and allowed you to attach a filter of a larger specification. Step-down rings work in the opposite way - they allow you to use a smaller filter on a larger lens thread (e.g., using a 67mm filter on a 77mm lens).
