I know Samsung NX is a great system. I am a fan of NX300 and NX Galaxy for a long time. Their 85mm 1.4 is seriously flagship killer among all 85mm 1.4 lens.
I got the NX500 for $375 last couple month, however I sold it. And the reason I left Samsung NX system is:
+ Sony A7 Full Frame used right now around $700 - $800 only. You can adapted EF, Nikon, FD, M43 , M42 to A7 Camera. With Full Frame that mean DOF is better.
+ The NX1, NX500 are great, but seriously, I don't like noise reduce to my JPG. I shoot raw, and I like NR = OFF, on my A7, I can shoot ISO 3200 - 6400+++ easy on raw, and noise like film grant, so beautiful.
+ I betray NX500, and my NX300, my first and my favor camera for long time, because No EVF.
+ I pick A7 and Olympus OMD, OMD give me EVF, body 5 Axis, lens at f/0.95, I can shoot at night with ISO 400 easy.
I don't shoot Video. However if I shoot Video, then Sony A7S is flagship killer.
Sorry Samsung, you betrayed us, no EVF for NX500, NX1 is too pricy compare to A7 FF. Samsung, I know you have great lens system already, but your camera design is just something ... I don't like the design.
I like vintage, retro design, bring me to camera world.. maybe not only me love this, but A7, Olympus OMD , the small factor and design bring more photographers to them.
The NX1 Design <-- I don't like it.
I love NX500, NX300 design, but plz, an EVF like Sony A6000 or Fujifilm X-E2 take too much space on your camera ? No. You just want EVF for NX1, NX30, NX Galaxy, that why we left your system.
Anyway, Samsung Lense is good or better than Canon L lens for sure. They lost the battle, because they didn't listen to their customers, they think they make an inovation, but we need something to shoot everyday, real world.
I will make an comeback to you, Samsung, when you make camera with 5 Axis body, vintage design, small factor with EVF. I miss my Samsung NX 45mm 1.8, 30mm f/2, tiny and mighty.
P/S: Also, Samsung, plz make your NX Software public, no one need it if they don't have your NX camera. Why you don't public the software? We always lost the CD all the time, f.u.k you, even I contact support, they have no link to download. Very hard to find someone use Samsung share that software on internet. D.A.M.N
