Super Telephoto Zoom. This long-range zoom provides a large focal range that’s perfect for sports and wildlife photography. The variable f/5-6.3 aperture may be a tad limiting for low-light shooting, so you’ll get the best performance while shooting in daylight.

Hyper Sonic Motor Autofocus System. Provides fast, silent operation in a wide variety of shooting situations. The Autofocus/Manual Focus switch also has a Manual Override position that enables full-time manual focus override for quick fine tuning.

Optical Stabilizer with Accelerometer. Helps to eliminate camera shake when shooting. For improved panning performance, Sigma has added an accelerometer to help detect horizontal and vertical movement when shooting in Mode 2.

High Image Quality. As a part of Sigma’s Sports line, this lens goes through Sigma’s rigorous A1 testing, ensuring high image quality. Two “F” Low-Dispersion elements, which perform equivalently to fluorite, eliminate chromatic aberration. Meanwhile, three Special Low-Dispersion elements maximize image quality.

Professional Build. The lens barrel is constructed of Sigma’s durable Thermally Stable Composite (TSC) material, which ensures minimal shrinkage in extreme conditions. The dust- and splash-proof sealing further ensures uninhibited shooting in messy situations, with water- and oil-repellent coatings on the front and rear elements to keep them clean. Its zoom-lock switch and rotating tripod ring give you ultimate flexibility when shooting from a tripod or monopod.

Dock Compatible. As part of Sigma’s Global Vision series, this lens is compatible with the Sigma USB Dock for Nikon F Lenses (separate rental item), allowing you to adjust the focus limiter, AF speed, microfocus, and OS settings through the Sigma Optimization Pro software.

Sigma TC-Compatible. This lens is officially supported by Sigma’s own “TC-1401 1.4x”:/rent/sigma-tc-1401-1.4x-teleconverter-for-nikon and “TC-2001 2x Teleconverter for Nikon”:/rent/sigma-tc-2001-2x-teleconverter-for-nikon.
