Tiffen 5246SDR 52-46 Step Down Lens Ring

The Tiffen 5246SDR Step Down Ring is a simple but practical accessory that bridges the gap between a 52mm lens thread and 46mm filters. If you already own filters in the 46mm size and have recently added a lens with 52mm front threads to your kit, this ring lets you continue using those filters rather than repurchasing them in a larger diameter. The ring threads securely onto the front of your 52mm lens, presenting a 46mm female thread that accepts your existing filters.

Made in the United States, the 5246SDR is machined from metal for a precise, cross-thread-resistant fit. It is extremely lightweight at just 0.64 ounces and adds minimal bulk to your setup. One important consideration with any step-down ring is the potential for vignetting: because the filter you mount will have a smaller diameter than the lens's image circle, the filter rim may intrude into the frame at shorter focal lengths. For telephoto and moderate focal lengths this is rarely an issue, but wide-angle shooters should test for corner darkening before committing to a step-down workflow.
