Ricoh has announced the new HD Pentax-D FA Macro 100mm f/2.8ED AW (All Weather) lens. This is the first Pentax macro lens to feature all-weather dustproof and weather-resistant construction. Ricoh says that when mounted to a weather-resistant Pentax DSLR, the new lens creates “a highly dependable, durable imaging system that performs superbly in demanding shooting conditions”.
The lens features a new optical design, although Ricoh says it’s almost as compact as its Pentax-D FA Macro 100mm f/2.8 WR predecessor. And as well as new insides, it also has a new exterior. The new design includes Pentax’s Quick-Shift Focus System. This enables photographers to instantly switch from auto to manual focus after the camera’s AF system locks on.
