Got some NX1 specs form a highly trusted source.
1) 1499 Euro for the body only
2) 28 megapixel APS-C sensor (said to be the best on market yet)
3) Phase detection af pixels on sensor
4) 154 cross type autofocus points
5) More than 10 fps per second (yet not specified by Samsung)
6) FullHD EVF (again said to be the best on market yet)
7) weatherproof body
8) Panasonic GH4 alike modern design
9) and no(!) Tizen os (unlike rumors published by other sites before)
I hope sources will soon send me some pictures of the NX1. Cannot wait to see that beast!
