Promaster 7029 39-52mm 轉接環

This step-up ring fit perfectly between my 52mm lens and a larger filter, no wobble or cross-threading at all. The brass construction feels solid and should hold up well over time.

Needed a step-up ring to use my 67mm filters on a 58mm lens, and this brass ring threads on smoothly without any wobble. The knurled edge gives good grip for tightening, which I appreciate.

Fits perfectly between my 52mm and 62mm lenses, and the brass threads feel much sturdier than the aluminum ones I’ve tried before. No light leaks or wobble at all.
