The German retailer Fotokoch has two new listings (white and black version) for a new Samsung NX 50-200mm f/4.0-5.6 i-Fn OIS lens. The entries have a different price (€349) and model number then the previous model. Samsung will probably release the new lens with the rumored NX-R mirrorless camera next month.
There is also a new white Samsung NX 16mm f/2.4 pancake lens (previously available only in black).
