Overview

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.

Pros & Cons

👍 Pros

  • Lets you share 49mm filters across lenses with larger 58mm threads, reducing filter purchases.
  • Lightweight aluminum alloy construction adds minimal weight and bulk to your lens.
  • Simple screw-on design requires no tools and installs in seconds.
  • Made in the United States with Tiffen's established manufacturing quality.

👎 Cons

  • The smaller 49mm filter can cause vignetting on wide-angle lenses due to the reduced diameter.
  • Does not allow you to use your lens cap on top of the ring and filter without a separate adapter cap.
  • Only bridges 58mm to 49mm specifically, so you need separate rings for other size combinations.
  • Stepping down significantly in size limits the usefulness compared to a step-up ring approach.

Frequently Asked Questions

It allows you to mount a smaller 49mm threaded filter onto a lens with a larger 58mm filter thread, bridging the size difference between the two.
Because the filter is smaller than the lens thread, vignetting can occur at wider focal lengths. This is more likely on wide-angle lenses where the smaller filter diameter may intrude into the field of view.
Yes, you can thread a 49mm filter onto the ring, but stacking multiple rings or filters increases the risk of vignetting and may add bulk to the front of your lens.
It fits any lens with a standard 58mm front filter thread, regardless of brand or lens type.
