Step-Up/Step-Down Rings

Prevent Vignetting
Step-up rings allow large filters to be used on lenses with smaller diameter filter threads; the filter will be much larger than the diameter of the lens. Use of step-up rings is often mandatory and routine with shorter focal length or wide angle lenses in order to prevent vignetting.

Step-down adapters allow smaller filters to be used on lenses with filter threads of larger diameter. This may result in vignetting so their use is normally not recommended.

Contact us with your size requirements as there are too many variations to list. Our stock rings cover 25.5 to 105mm and custom sizing is available.
