Pentax have launched the Pentax-DA 55-300MM F4.5-6.3 ED PLM WR RE Lens.
The new lens features a pulse motor (PLM) and adopts a ‘rear-focus’ system – both of these changes result in faster autofocus acquisition times (8.3x at wide angle and 1.7x at telephoto), as well as quieter overall autofocus performance when compared to its predecessor. Ricoh also claims that, when the lens is mounted on the new K-70 DSLR, a new autofocus algorithm ensures greater precision and faster operation with dimly lit subjects.
The lens is 10% lighter than the old 55-300mm, is fully weather-sealed and focuses down to 0.95m/3.1ft Rounding out the key specs and changes is an electromagnetic diaphragm control system, which, according to Ricoh, will provide smoother aperture control during video recording.
The HD Pentax-DA 55-300mm F4.5-6.3 ED PLM WR RE lens list price is $399.95/£399.99.
