The Sigma 60-600mm F4.5-6.3 DG OS HSM | Sports lens is the newest high-zoom ratio standard-to-supertelephoto zoom lens in the Sigma Global Vision lineup. Replacing the venerable 50-500mm EX lens, which was nicknamed by fans the “Bigma”, this new superzoom lens is completely redesigned while maintaining the mind-blowing 10x zoom ratio of its lineage. As a Sports lens, the weather-sealing is first-rate, ready and raring for the roughest conditions; while the Multi-Material Construction shaves weight, pairing Magnesium and Thermally Stable Composite along with Carbon Fiber reinforced plastic to make it durable while staying portable. Packing 25 elements into 19 groups, and weighing under six pounds, this lens packs a lot of punch! From standard to supertele with either a push-pull on the barrel or the wide grippy zoom ring, it also manages to close focus to under a foot from the front elements at 200mm with 1:3.3 magnification.
The three-zone focus limiter switch and Autofocus, Manual Focus, and Manual Override switch have been added, along with a slew of Sigma’s exclusive Global Vision features and functionalities have also been added: Custom Functions Switch to deploy Lens Customization settings via the USB Dock and Sigma Optimization Pro, Zoom lock at all marked focal lengths—a feature introduced to the photography world with the pair of Sigma 150-600mm lenses—and 100% testing for optical performance at our Aizu, Japan factory.
I had a few days to get familiar with the lens in the leadup to PhotoPlus 2018, and I am very, very impressed. Wide open at 600mm it is super-sharp on the focal plane, and the near-to-far zoom comparisons to show total reach and range are simply stunning! Straight out of the box, autofocus speed is super-fast, and faster still when focus limiters are employed. AF was quick as…well…let’s just say tracking birds in the sky, even in dusky predawn light, was no problem at all.
