The HD Pentax DA 55-300mm f/4-5.8 ED WR is a telephoto zoom that's weathersealed to complement the company's recent SLRs. It also gains Pentax's latest 'High Definition' coating to minimize flare and ghosting. Aside from that, the specifications are practically identical to the existing smc DA 55-300mm f/4-5.8 ED lens. The 83-450mm equivalent angle of view makes it well-suited to subjects such a sports and wildlife.
