Adapter ring for Samsung NX 1000

I had a 52 mm pole filters, I wanted to screw my NX 1000 camera because the lens diameter of 20 / 50mm Kit - is 40.5mm lens, I ordered from Amazon this adapter ring. (40.5mm to 52mm). It can be easily screwed onto the lens thread .., also the pole filter. Can easily turn into in the thread ... The ring is processed with value and inexpensive .Somit can also be other filters with 52 mm diameter use. Especially for cameras with a small lens diameter adapter rings are very helpful. For fast delivery and solid packaging, there are four stars from me.
