This camera did not recognize the original Samsung lenses. I disassembled and modified it, to allow the mounting of my lenses for rangefinder cameras which protrude at back: the Russar MR-2 5.6/20mm and the Jupiter 12 2.8/35mm.
On the left, my NX11, the altered NX100 on the right. Obviously, it will now only operate with manual lenses!
The sensor of the first NX100 soon showed to be defective. So as an opportunity arose, I bought another one, which back part (including the screen) was broken. And I transferred on it the complete back of the first one. As meanwhile I had bought the Sony A7, the transformation for using Jupiter-12 and Russar was no more necessary, and I did not take the risk of doing it again (this camera works perfectly with original Samsung lenses).
It makes me a bicolor NX100: silver front and black back!
