Saves me from buying extra filters for other lens
Good value adapter. As I only bought 77mm filters for my pro lens. It is made of aluminum, not brass as those more expensive ones. It does not come with a case, so I use the other filter case for it. No issue on fitting at all.
i use this to hold a matte box/filter holder off of my rb67 pro/s.it is the best value for an adapter of good quality.
I use this step up ring for my 18mm-105mm Nikkon lens. It allows me to directly attach 77mm filters. The action is fairly smooth but the powder coating sounded a little crunchy initially.But the machining is nice. It is aluminum, so take care not to over tighten the filter to the ring and ring to the lens. It would be easy to strip or damage the components if you are not mindful. I suspect those who are negative on this product don't know how to care for equipment properly.
