Perfecto
Se acopla muy bien a la griii y el filtro de 49mm. Encajan perfectamente.

It works!
It fits snuggly in the GR's bayonet mount and holds a 49mm filter. Exactly what I needed.

Good option!
One of the things I dislike about point and shoot cameras is the lack of polarization. This works well with my filters.

NiSI makes great stuff
Always a first stop for filter gear. Another well made, high quality product.

A nice way to keep dust out and not as expensive as the OEM.
It works. It is a very very solid purchase. I bought it to use as a way to keep dust out of the GR sensor( we all know this to be an issue ). SO essentially, I bought it, a filter, and a hood. Doesn't make the GR back pocketable but it does work extremely well to keep out dust. I think the materials are solid and quality. Super easy to use. You just take the filter ring off and then add this to it. Everything works well, except the fit is not as snug as I want it. Let me put this out there, it doesn't fall off. It stays on. I just would have preferred it to be a little more snug. Edit/Update: I still hold the opinion that it could be a snugger fit, it kinda bugs me. But since purchased, I have not received any dust to the sensor and am very happy with the quality of the adapter. I added a B+W filter and hood to the front and works brilliantly.

Good quality construction, but iffy fit
It fits ok, but after using it for a few months, it's not a very snug fit. Not sure if the OEM version would fit better, but using this with the wide angle lens (which is quite heavy), I am not comfortable with this holding the lens securely. These attach by fitting into a groove around the lens on the camera body, then rotating it until it "clicks" into place, but this aftermarket version doesn't click in very well. I use a piece of black electrical tape between this and the camera body to prevent any accidental movement. Otherwise it seems to be decent quality aluminum construction, and the threads for filters/lenses are smooth. Just worry a bit about the attachment to the camera body.

Perfect

Fits well and does not add too much bulk
Fits well and serves to allow filters to protect the lens mechanism cos not weather sealed. Paired it with K&F concept variable ND and polarising filters - images still sharp.

All metal alternative. With a bonus ring!
Cleaner all metal design compared to the Ricoh's. Not without its drawbacks - doesn't lock into place. No biggie. Came with a bonus silver ring! At nearly a third of the price - its a good buy.

incompatible with griiix
I thought it would fit but It doesn’t fit griiix.
