Tiffen 5849SDR 58mm to 49mm Step Down Ring

The Tiffen 5849SDR Step Down Ring is a simple but essential adapter that allows photographers to mount 49mm threaded filters onto lenses with a 58mm filter thread. Made from aluminum alloy, it provides a secure, cross-threaded-resistant connection between the two different sizes. This is particularly useful if you already own a set of 49mm filters and want to use them on a lens with a larger front element, saving the cost of purchasing duplicate filters in every size.

Because stepping down means placing a physically smaller filter in front of a larger lens, users should be aware of potential vignetting, especially on wide-angle lenses where the smaller filter diameter can encroach on the edges of the frame. For standard and telephoto focal lengths, this is generally not a concern. The ring threads on and off cleanly and sits flush against the lens, keeping your setup compact and ready to shoot.
