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. And they also announced the AF540FGZ II and AF360FGZ II Pentax-branded flash units. Both are updates to existing models, now boasting weather-sealed construction to match Pentax’s line of weatherized DSLRs. The new flash units also feature built-in LED lights, intended for video recording.
