Ricoh Imaging has announced an updated set of Pentax DA Limited primes, with improved lens coatings and circular aperture diaphragms. Based on the existing 15mm F4, 21mm F3.2, 35mm F2.8 Macro, 40mm F2.8 and 70mm F2.4 designs, the 'HD' versions gain Pentax's multi-layer HD (High Definition) coating, promising reduced flare and ghosting, and include diaphragms that are completely rounded at large aperture settings to give attractive background blur. Other specs, including physical dimensions, optical formulae, minimum focus distance and maximum magnification remain largely unchanged. The lenses will all available in September 2013, in a choice of silver or black.
