Pentax 21340
The 150-450mm zoom reaches an effective 675mm on APS-C bodies, and its 21-seal weather-resistant build ensures reliable operation in harsh field conditions. Extra-low dispersion glass and HD coatings deliver sharp, high-contrast images while the Quick-Shift Focus system allows instant manual override. This lens is best for wildlife and sports photographers using Pentax DSLRs who need rugged, long-reach telephoto performance.
