Photographers now have a lens that opens up new possibilities for creative work with an impressive 10x lens that tops out at 600mm. The SIGMA 60-600mm zoom is both dust- and splash-proof, with special water- and oil-repellent coating on the lens front. It comes with a versatile tripod socket which has a replaceable lens foot with 90-degree click stops and Manual Override that allows for selection of two full-time manual modes. Constructed with 25 elements in 19 groups, with a 9-bladed diaphragm, the lens is 120.4 x 268.9mm when “unzoomed”, an easy fit for many camera bags and backpacks.
