DA 40mm f/2.8 Limited
The smc Pentax-DA 40mm f/2.8 Limited is a pancake lens for the Pentax K-mount. At only 0.6 inches (15 mm) long, it was the smallest lens made by Pentax until the 40mm XS lens was introduced. The lens has a 35mm equivalent focal length of 60mm; it is part of the Limited series of high-performance compact lenses. In August 2013 it was re-released with improved lens coatings and rounded aperture blades as HD Pentax-DA 40mm f/2.8 Limited.[1]
DA 40mm f/2.8 XS
The SMC Pentax-DA 40mm f/2.8 XS is an even thinner version of the SMC DA 40mm lens, at 9.1 millimetres (0.36 in) thick, released by Pentax on February 2, 2012. It features an aesthetic design by Marc Newson[2][3] to match the Pentax K-01. It is currently one of the thinnest autofocus pancake lenses ever made.
