Because telephoto lenses use high-quality optical glass, we recommend you use our 3 peak range.

For lenses with a focal length 100mm or greater, your telephoto needs to be paired with the best quality optical glass to allow the best sharpness throughout the zoom range.

Thus, we recommend you pair your lens with a UV or CPL filter made with German Schott Glass and a 2 peak fixed ND filter. We recommend fixed ND filters over variable ND filters because it means there are fewer layers of glass over your lens.
