A 75° turn of the zoom ring takes you all the way from 150mm to 500mm for a fast zooming experience. A zoom lock keeps the lens from extending when being carried. An optionally attached lens foot adds 0.3 lb to the 3.8 lb weight of the lens. As you’d expect, the lens is weatherproof, packs 25 glass elements into 16 groups, features the latest coatings from Tamron, and features a 7-bladed rounded aperture diaphragm.
