A Samsung 300mm f/2.8 XF ED lens which appeared in a corporate video on YouTube is a ?prototype?, the Korean manufacturer has confirmed to Amateur Photographer.

However, a spokesman for Samsung?s head office added that ?there is no definitive plan to launch this lens into the NX system?.

The lens was spotted in Samsung?s ?NX Lens Planners Interview? which was broadcast on YouTube earlier this month (see below).
