The biggest surprise so far for me from Photokina was the announcement from Samsung of the NX1 with a specsheet on paper that sounds like a technological jump over every other APS-C, m43 or other camera body available. It remains to be seen how it works in the real world. If larger sensors benefit from BSI technology as much as smaller sensors, it's conceivable that it could at least equal todays high res 35mm format sensors in terms of noise and colour depth. http://www.dpreview.com/articles/7933116058/samsung-nx1-debuts-with-aps-c-backside-illuminated-cmos Now, a camera and a system are two entirely different things. Samsung need to pad out their primes, particularly on the wide end, open up their mount to Sigma, Tamron and other players. They also need to get a solid lighting platform going .... my point is that they still have work to do and I don't see many pro's dumping their EM1's, D800's for this yet given its such a juvenille ecosystem but based on this photokina, Samsung really do look to be making the right moves especially in the areas of video and hybrid.
