Deco Photo 55mm→40.5mm ステップダウンリング

The threading is smooth and seats perfectly flush on my 55mm lens, so there’s no wobble when I screw on my 40.5mm telephoto. I’ve used it all weekend shooting birds and the ring hasn’t loosened even once.

I needed this ring to use a compact wide-angle lens on my 55mm filter thread, and it fits snugly without any wobble or cross-threading. The matte black finish blends in perfectly with the lens.

The threading is smooth and precise, so the ring screws on without any wobble or cross-threading. It's a solid little piece of metal that does exactly what it says, letting me swap in my 40.5mm wide-angle lens in seconds.
