All-In-One Superzoom. Covering a focal length equivalent to 29-480mm after sensor-crop factor, the Sigma 18-300mm 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, with the 18-300mm treading into wildlife territory. The slower f/3.5-6.3 variable aperture rules it out for any low-light shooting, but that’s not what this type of lens is made to do.
Optical Stabilization. The built-in stabilizer offers up to 3.5-stops of correction to help 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. Four FLD and one SLD elements minimize chromatic aberrations while maximizing image contrast and sharpness throughout the zoom range. 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.
Dock Compatible. As part of Sigma’s Global Vision series, this lens is compatible with the Sigma USB Dock for Canon EF Lenses (separate rental item), allowing you to adjust certain parameters through the Sigma Optimization Pro software.
