Step-up/step-down adapter ring KiwiFotos SB2000 55mm→58mm reverse mounting

The KiwiFotos SB2000 step-up/step-down adapter ring converts between 55mm and 58mm filter threads and allows reverse mounting of lenses and filters for macro and creative close-up photography. Manufactured in metal with screw-type threading, the adapter provides a compact and reliable connection that lets photographers attach 58mm accessories to lenses with a 55mm thread or use 55mm filters and caps on 58mm lenses. The reversible design supports mounting a lens backwards on a camera body or attaching reversed filters and accessories for extension and alternative optical effects.

Advantages

The metal construction ensures durability and stable thread engagement while remaining lightweight and compact for transport. Precision threading provides secure fitment with minimal wobble, reducing the risk of cross-threading and ensuring consistent alignment between lens and accessory. Its reversible capability expands creative options for macro work without requiring additional adapters or heavy equipment.

How to use

To adapt a 55mm lens for 58mm accessories, screw the adapter onto the lens’s 55mm filter thread, then attach the 58mm accessory to the adapter’s external thread. For reverse mounting a lens, attach the adapter to the lens rear or front thread as appropriate and secure the reversed lens to the camera or to another accessory. Ensure threads are clean and aligned before tightening to avoid cross-threading. Hand-tighten until snug; do not over-tighten to protect the threads and the lens finish.

Usage recommendations

Inspect and clean the threads on both the lens and adapter before use. When using reversed lenses, support the lens body to avoid strain on the adapter and camera mount. Store the adapter in a protective pouch when not in use to prevent dents or deformation of the threads.
