I just gave it a test run and seems to work pretty well. The lens is fixed in place and it doesn't make it loose at all. the threading seems to work well too.

49mm macro reverse adapter fits good to my lens.

bought to capture rings on a wedding close up. works great, just don't over-tighten it to your lense as it will be a pain to remove it. also be very gentle when you click it onto your camera as if you are too rough when doing it, you will hear metal on metal sounds which is never good. Overall its a really cheap way to do macro work

Worked better than expected. transformed an old 25 dollar lens into a pretty good macro lens.

Excellent! Did the job. I used this to reverse a Pentax vintage lens for macro photography use. Works as described.

This this is great, must use with a manual lens (both aperture and focus). Image is two quarters.

One star knocked for feeling somewhat flimsy. Mounts my 50mm canon without issue.

Does the job!

Se adapta excelente a mi lente, se ve y se siente de buen material.

Works perfectly.

Item attached to my camera and lens just fine but the camera only saw white couldn’t use it at all.

Me suis trompée de grandeur, donc inutile
