Pentax smc DA 55-300mm F4-5.8 ED review
smc PENTAX DA 55-300mm F4-5.8 ED With its wide coverage over medium- to
super-telephoto ranges, the smc PENTAX-DA 55-300mm F4-5.8 ED is perfect for
a wide range of telephoto applications, including portraits, sports and
landscapes. Incorporating two ED (extra-low dispersion) optical elements,
it offers superb optical performance, with minimal chromatic aberrations
over the entire zoom range. The PENTAX-original SP (Super Protect) coating
repels dust, water and grease to keep the lens clean and image quality at
its peak.
