My Review of Adorama Step-Up Adaptr Ring 67mm Lens to 77mm Filter
Adorama Step-Up Adap
Good Step up ring
Describe Yourself: Photo Enthusiast
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.
