Now Samsung NX system is underdog with great value. Something that Pentax years ago.

Interesting bodies

• Samsung NX1 - video king for APS-C cameras, current top camera
• Samsung NX30 - ex top camera, available for $460 and up on ebay . It is hard to get such good camera with EVF and AMOLED screen for so cheap in any other system.
• Samsung NX20 - early top camera, available for $260 and up on ebay . Still with good EVF and AMOLED. FullHD video and Wi-Fi. Steal.
• Samsung NX300. Little gem. Amazing build, AMOLED tilting screen. From around $280 on ebay.

Optics

Most optics is of very good quality, quite cheap, except one ultrazoom (but it is very ok for video).

Best ones: 16-50mm F2-2.8 zoom, 60mm macro, 85mm F1.4 S, 30mm F2, 12-24mm wide zoom, 16-50mm PZ lens.

Samyang and Rokinon optics can be got with good discount with NX mount (check $235 35mm F1.4 I posted in NX1 topic).

Connectivity

Samsung is known for best connectivity options and very good Wi-Fi speed (as they are pro in implementing Wi-Fi in smartphones).

Firmware

Bodies before NX1 can have small issues with video compression. It is BaseLine profile, 1 ReFrame only, no CABAC. Ala GH1.

Software

Samsung cameras come with full fledged Adobe Lightroom (except newest NX500). Take it into account also, looking at the prices.

Sound

On some bodies it is no mic input as well as headphones out.

Yet unusual hack to this exist, you will need small Samsung EM10 microphone.
It has headphone output and internal ADC. If you want to attach dynamic or electret lavalier mikes you'll need to rip it apart and solder wires to the original capsules.

Good, cheap, compact, AF fisheye.

Pin Out

• Pin 1: SPI Clock - Body (Master) generates clock signal to synchronize SPI communication. (Normal High)
• Pin 2: SPI MOSI - (Master Out Slave In) Body sends data to Lens. (Normal Low)
• Pin 3: SPI MISO - (Master In Slave Out) Lens sends data to Body. (Normal High)
• Pin 4: AF Tick - This line is used only when AF is performed. This tick commands lens report the lens status (AF location, moving status, etc). (Normal High)
• Pin 5: Lens Data Ready - (Normal High) Lens set this line LOW when lens has data ready to send Body. Once this signal set LOW by lens, body will generate SPI Clock, and Lens will transfer prepared data with the clock signal.
• Pin 6: GND (0V)
• Pin 7: Power (3.3V) - It is a power source for microcontroller in Lens.
• Pin 8: Power (5.0V) * It is a power source for motors in Lens (AF and Aperture motor)
