Compré un flitro ND variable, pero de 82mm y con los anillos puedo adaptarlo a cualquiera de mis otros objetivos.Calidad en metal y muy contento con la compra.

There are lots of reviews complaining about the threads. Mine came threaded together half and half. The threads are great, the rings thin, if you tighten them it can be hard getting a grip to unscrew them, but they still come apart without incident. If mine had come cross threaded I would have sent them back, but they didn't and I didn't. They are nicely made, work great, and quite inexpensive.

excelente artículo a un muy buen precio, bueno para aquellos que necesitamos unos adaptadores para filtros y no estar gastando mucho dinero en comprar un filtro para cada diámetro de lentes

中国のねじ工場の暇な時にどっかでつくらせたんでしょうが、制度も仕上げも悪く、日本製のレンズやフィルターに組み合わせると傷だらけになります。ゴミです。買ってはいけません。

I have three lenses, and rather than buy the same filters for each, I'm standardizing on the largest, then using the rings to use them on the smaller lenses. I only needed two of the rings, but the kit was inexpensive, and they fit my lenses and filters.
