Samsung offer a glimpse into the work of their lens R&D group on the NX range. It's not overly enlightening and is mostly a PR piece but it's worth a look nonetheless, particularly the video conversations. Part I covers lens developers and part II looks at lens planners. (via Mirrorless Rumors)
Samsung keep promising lenses, but they have so far failed to materialise. I appreciate it must be very difficult for manufacturers to launch a new system, however there is little point investing in a camera body if there aren't more than a very few lenses available to actually buy.
Come on Samsung, get them in the shops. Or are you losing interest in the NX system already?
