EasyFoto Metal Lens Hood for Samsung NX 20-50mm F3.5-5.6 ED, Nikon 1 NIKKOR 10MM F2.8 Lens

this lens hood is advertised to work with other camera brands/lens but after doing some research I discovered that this also works with my Sony 16mm PZ lens. I've scoured the site and I realized that this is exactly the same as the other brand that I saw which is priced much higher. it doesn't have any vignetting even with my wide lens and as a bonus it gives me an option to attach a 62mm filter at the end of the hood.

I am using this product on Samsung 20-50mm lens on Samsung NX100, it is nice metal hood, however, I cannot put my original cap to protect my lens after the hood on it (which I thought it's compatible).

It fits my NX 20-50MM Lens BUT I have to push on the lens while screwing this hood or else it falls off. I don't like doing that as it puts pressure on the lens gears/motor.
