All-In-One Zoom. Covering a focal length equivalent to 27-300mm after sensor-crop factor, the Sigma 18-200mm is great for those who want to mount one lens to their camera and forget about it. All-in-one zooms are popular for travel and general every-day use. The slower f/3.5-5.6 variable aperture rules it out for any low-light shooting, but that’s not what this type of lens is made to do.

Optical Image Stabilization. The built-in stabilizer helps to prevent camera shake, allowing you to shoot at slightly lower shutter speeds.

High Build and Image Quality: As a member of Sigma’s Contemporary lens line, it goes through Sigma’s rigorous A1 testing to ensure it leaves the factory performing flawlessly. A double-sided aspherical lens maximizes focal range while keeping the lens small and lightweight, special Low Dispersion (SLD) glass keeps chromatic aberrations to a minimum, and the Super Multi-Layer Coating reduces lens flare and ghosting. The barrel is made of a lightweight TSC compound that gives the lens a solid, sturdy feel. The HSM focusing motor gives fast, accurate autofocus performance with a non-rotating front element thanks to the internal focusing design.

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 certain parameters through the Sigma Optimization Pro software.
