ProOptic Step-Down Adapter Ring 40.5mm Lens to 37mm Filter Size

Enhance your photography experience with our Step-Down Adapter Ring, designed to enable the use of smaller 37mm filters on lenses with a larger 40.5mm diameter thread. This precision-engineered adapter ring is an essential tool for photographers looking to expand their creative possibilities without investing in a wide array of filters.

The first number in the product name refers to the lens diameter that the adapter ring screws into, while the second number denotes the filter size it accommodates. Crafted with meticulous attention to detail, this adapter ring ensures a secure and seamless connection between your lens and filter, providing you with the flexibility to use a diverse range of filters on a single lens.

Please note that using step-down rings may cause vignetting, a reduction in the image's brightness or saturation at the periphery compared to the image center. This is a common occurrence when using step-down rings and is not a product defect.

Whether you're a professional photographer or a hobbyist, our Step-Down Adapter Ring 40.5mm Lens to 37mm Filter Size is a valuable addition to your photography kit, offering you the versatility to explore different filter effects with your existing lenses.
