The adapter works as expected. I was able to fit an old Pentax Lens to my Canon R5. The fit of the Pentax lens was tight, so I had to turn it with a bit more force than expected until it locked in. After overcoming my initial hesitation, it was no problem to connect the lens to the camera.

I want good UV filter for vintage lens and perfect quality! Good price

Ein guter uv Filter

Ich benutze dieses Mikrofon an meiner Nikon D5200, es funktioniert einwandfrei und ohne Probleme! Die Verarbeitung finde ich auch vollkommen in Ordnung. Hier stimmt das Preis-, Leistungverhältnis!

Filter built is decent and also quality seems fine, but there are 2 things you should consider before buy (I did not and I regret it): 1/ filter end is bigger than filter thread, so you cannot use original lens cap from the lens (so everytime you have to remove filter for safety, loosing time and flexibility) 2/ thanks to bigger diameter of the filter and extra knobs for changing ND, you cannot attach the lens hood, which I did not realized and probably will need to buy another NDs...

i used an old 50mm Nikon lens i have and it worked just fine.

It's good for my kit lens.

not practical when you have lens
