The picture above shows the new Pentax DA 560mm f/5.6 lens which were already known to be slightly different from the prototype.
The design is slightly different from the prototype images that were seen several months ago. One of the unique features of the DA 560mm comes with the possibility of disassembling or collapse it. The lens has a long focus designed to provide lower optical aberrations without raising cost. The price which is still unknown, is expected to be lower than similar lenses from other manufacturers. The Pentax DA 560mm f/5.6 lens is expected to hit the stores in the first quarter of 2013.
