Works perfectly for a good price. What more can you ask.
... as advertised. Seems solid enough. The only trick with this, is to make sure you remember to put it in your camera bag.
As expected, it screws on to a 52mm lens and allows for me to use a 77mm filter.
I have been using this to attatch a good - big filter to my small action camera. Super Happy.
Does the job. Be careful not to adjust it to snug or it may get jammed.
Using it on the Viltrox 23mm for X Mount and it works great.
Works just fine! Recommended.
I purchased a vintage lens with a 52mm filter ring and wanted to use it on a Leica Monochrome Type 246. I had a set of B+W 77mm filters (yellow, orange, and green) and a 77mm lens hood. I needed to step-up from 52-77mm. to be able to use the filters. The Sensei 52-77 was the right ring for the job. It is well made and screws onto the lens without binding or sticking. The ring is much more economical than purchasing three new 52mm color filters.
