With a focal length of 35 mm and a high-speed autofocus, this lens is equally suited to snapshots, landscape photographs and portraits. The metal housing gives it a high-grade appearance and the robustness required for outdoor use. Moreover, the lens is sealed and weatherproof, allowing for use down to a temperature of –10 degree centigrade, yet at 180 grams it is still very light. The aperture ring can be easily operated with one hand while the other hand holds the camera.
