Sigma has announced two new full-frame compatible 150-600mm lenses. The 150-600mm F/5-6.3 DG OS HSM Sports delivers enhanced, professional-grade optics and greater durability for high-action photographic situations. The 150-600mm F/5-6.3 DG OS HSM Contemporary is a versatile lens that offers similar performance in a more compact and portable design.
The two lenses join Tamron’s 150-600mm f5-6.3, announced earlier this year, as having the longest focal range available for full-frame SLRs.
Both versions of the 150-600mm F/5-6.3 DG OS HSM feature dust and splash-proof features, as well as new water and oil-repellent coating on the front and rear lenses. They boast an updated Optical Stabilizer (OS) that features an accelerometer for improved vertical and horizontal panning, essential for bird, wildlife and motor sports photography. Two new switches were added for ease-of-use, including a new zoom lock switch capable of locking at any focal distance and a Manual Override (MO) switch for improved control of focusing performance. An enhanced auto focus (AF) algorithm and Hyper Sonic Motor ensure quiet and fast AF.
The 150-600mm F5-6.3 DG OS HSM Sports offers the highest level of performance and durability with a splash and dust proof construction, and features dimensions of 122mm by 290mm, with a weight of around 2.8kg. It contains 24 lens elements in 16 groups with a minimum aperture of f22 and minimum focusing distance of 102.4 inches. Its maximum magnification ratio is also 1:5. The Sports lens will be available in Sigma, Canon and Nikon mounts.
The 150-600mm F5-6.3 DG OS HSM Contemporary lens has a smaller build than its Sports counterpart. It is equipped with a splash and dust proof mount, and its dimensions are 105mm by 260mm. The lens will feature 20 elements in 14 groups with a minimum aperture of f22 and minimum focusing distance of 28cm. Its maximum magnification ratio is 1:5. It will be available in Sigma, Canon, Nikon and Sony mounts.
The lenses will be available in the fourth quarter. Overseas websites are tipping the Contemporary version to go head to head with the Tamron 150-600mm in terms of price, with the Sports model a few hundred dollars more.
