HD Pentax-D FA 21mm f/2.4ED Limited DC WR lens for Ok-Mount full-frame DSLRs. The corporate says that this ultra-wide prime is optimized for visible traits that may’t be measured in numerical values alone.
Ricoh says that the HD Pentax-D FA 21mm f/2.4ED is able to making pictures look extra real looking, and captures the prevailing ambiance and true-to-life sense of depth in a scene. The 21mm ultra-wide-angle focal size, not beforehand accessible within the FA Restricted collection and what Ricoh says is good for panorama pictures, provides “a brand new perspective of visible expression to the Restricted collection.” When used with PENTAX APS-C cameras, the brand new lens gives a focal size equal to 32mm within the 35mm format.
The lens contains a sturdy, weather-resistant construct that Ricoh says makes it capable of stand up to the pains of difficult photographic situations, citing particularly waterfront areas or within the face of a sudden rainstorm.
