I wanted to buy a cage for my Samsung NX1 long time ago, but the price used to be over USD$300 for all different options in the market.
Today i just realized that the Varavon Armor II Standard Cage was only USD$50. Coudn't skip the chance
Here is the link for the cage. I hope you will find usefull
ARMOR II - NX1 STANDARD CAGE (50 bucks)
ARMOR II - NX1 PRO CAGE (60 bucks)
