A simplified weather-resistant construction and an extra-smooth autofocus operation using a built-in motor, in addition to its high 7.5-times zoom ratio, allow the DA 18-135mm WR to accommodate a wide range of subjects and scenes that photographers come across in their shooting sessions — from scenic images and snapshots to portraits and sports photos.
