Lens Adapter Rings to help you fit our 77mm FX Filters to a wide array of other lens sizes!
All of the filters that we offer come in 77mm or 82mm thread by default.  Currently, we only offer 3 Step-up Rings and 1 Step-down Ring, that are compatible with our 77mm filters.  These do not work with our new 82mm filters. So, if you have a 77mm thread lens then you can screw our 77mm filter right on. Otherwise here is how to make those adapters work...
All lenses have a specific thread size listed on the lens itself. You can find this number on the inside or the outside of your lens (see example photos below). Once you have that number you can determine what Step-up or Step-down ring is right for you.  A Step-up Rings is needed when your lens thread size is lower than 77mm. A Step-down Ring is needed when your thread size is bigger than 77mm. Click here to see our

The first number denotes the filter thread specification of the lens on which the step-up ring is to be used. The second number denotes the filter diameter specification that will be screwed on to the wider end of the ring.
Are step-up and step-down rings the same?
The step-up ring simply increases the lens diameter and allows you to attach a filter of a larger specification. So that you don't have to buy or carry multiple filters for all the lenses you have. Saves money & bulk.
EXAMPLE: Let's say you have the popular Canon 50mm f/1.4 lens. The filter thread specifications reads 58mm. Our Prism Lens FX Filters only come in 77mm and 82mm. Luckily we have a 58-77mm 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 58mm lens. The step-up ring simply increased your lens diameter and allowed you to attach a filter of a larger specification.
Step-down rings do the exact opposite of a step-up ring. They adjust a larger lens thread to accommodate a smaller filter... When using step-down rings and filters, one can notice a lot of vignetting. Basically, the corners are getting less light because of the tunnel that is created.
