The same source sent Photorumors and me an update about the NX system. There will be new NX cameras and new EX-2 substitute (no surprise) but the pre announced 16-80mm has been cancelled and there will be another advanced zoom lens instead. In total at least two (and maybe three) lenses will be announced at Photokina.
Samsung remains a bit of a mystery for me. They keep saying they want to become the number one in the mirrorless system. But they really have to invent some kind of magical products in order to archive that. To be technologically on par with the others isn’t enough. Jusy a weird idea, they should buy Leica and create a Samsung-Leice mirrorless EVF system :)
