Whatever your challenges are when you're shooting outside, this Sigma Photo 120-400mm f/4.5-5.6 lens will have you covered. Fast action sports at your daughter's lacrosse match? The long reach will get you the dramatic close-up from across the field. A rare, colorful finch near the top of the canopy during your woodland hike? Optical stabilization lets you bring home sharp, vibrant pictures while working hand-held because you can shoot at slower shutter speeds. And quiet, fast autofocus means you'll be ready for candids and architectural details while traveling, even if the ideal moment is fleeting.
Careful attention to the optical build quality has yielded a lens that's sturdy, sharp across the entire frame, and free of color irregularities throughout the zoom range. If you're taking your camera outside at all, for almost any purpose, a zoom telephoto like this one is a welcome addition to your kit.
