What We Like
+Constant f/4 aperture throughout entire 300-600mm range—rare for a super-telephoto zoom
+Delivers near-prime-lens optical performance with 2x zoom versatility
+Aggressive pricing at ~$6,000 vs. $13,000+ for comparable 600mm f/4 primes
+Powerful 5.5-stop optical stabilization with OS2 algorithm and panning mode
+Professional-grade build with magnesium alloy body, carbon hood, and weather sealing
+Fast, precise High-response Linear Actuator autofocus with exceptional subject tracking
Worth Knowing
−Extremely heavy at 3,985g (8.8 lbs)—requires monopod support for handheld shooting
−Sony E-mount version limited to 15 fps burst mode and no teleconverter compatibility
−At f/4 wide-open, optical performance slightly trails true f/4 primes; stopping down one stop recommended
−Longer focus throw and slower AF compared to Sony FE native lenses like the 200-600mm

About This LensThe Sigma 300-600mm F4 DG OS Sports is a revolutionary large-aperture ultra-telephoto zoom lens that delivers all the convenience and versatility of a zoom lens with the superior optical performance of an ultra-telephoto prime lens. This rare lens is simultaneously both very expensive (at $6000 USD) and also a great bargain relative to the competition, offering 300mm, 400mm, 500mm, and 600mm F4 near-prime performance in a single package. It's a big lens (167mm in diameter and 467.9mm in length) and weighs nearly 4 kilos (3985g), but its build quality is easily on par with any 600mm f/4 telephoto from Sony, Nikon, or Canon. | |
