Bangalore, India – November 20, 2014 – Sigma India, brought to the country by Shetala Agencies – India’s exclusive distributor of Sigma Corporation – a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, has unveiled the new 150-600mm F/5-6.3 DG OS HSM high-performance, hyper-telephoto zoom lenses that celebrate significant optical and build advancements. The lens adds to the company’s impressive roster of Sports lenses in the Global Vision lineup. The company also unveiled the 18-300mm F/3.5-6.3 DC Macro OS HSM Contemporary lens.
The 150-600mm F/5-6.3 DG OS HSM Sports delivers enhanced, professional-grade optics and greater durability for challenging, high-action photographic situations. The lens offers the highest level of performance and durability with a splash and dust proof construction. It contains 24 lens elements in 16 groups – including two “F” Low Dispersion (FLD) and three Special Low Dispersion (SLD) glass elements – with a minimum aperture of F/22 and minimum focusing distance of 260 cm. The 150-600mm F5-6.3 DG OS HSM Sports features dust and splash-proof features, as well as new water and oil-repellent coating on the front and rear lenses. It boasts 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 lens is compatible with Sigma’s newly announced lineup of Global Vision teleconverters, which are effective up to F/8. The lens features a maximum magnification ratio of 1:5. The Sports lens will be available in Sigma, Canon and Nikon mounts.
Designed exclusively for APS-C camera sensors, the new 18-300mm F/3.5-6.3 DC MACRO OS HSM features a 16.6x high-ratio zoom lens which equates to a 27-450mm zoom range. It incorporates four FLD glass elements, which have performance equal to flourite, in addition to one SLD glass element. This enables the lens to minimize the chromatic aberration, especially toward the telephoto-end, and provide clear image quality with high color fidelity. The lens offers a minimum focusing distance of 38 cm, with a maximum magnification ratio of 1:3. To enhance the macro capabilities of the lens, Sigma Corporation has also designed a dedicated close-up AML72-01 lens that pairs with the 18-300mm F/3.5-6.3 to offer a maximum magnification ratio 1:2 and changeable angles of view. Even when this close-up lens is attached, the image taken at maximum magnification ratio, at 300mm, infinity, shows very little difference in modulation transfer function (MTF).
The 18-300mm F/3.5-6.3 DC MACRO OS HSM incorporates a bigger and newly developed Hyper Sonic Motor (HSM) that ensures high speed and quiet AF. Additionally the Super Multi-Layer Coating reduces flare and ghosting, to provide the user with sharp and high contrast images. The lens will be available in Sigma, Nikon, Canon, Pentax and Sony mounts; Pentax and Sony mounts will not offer OS.
All of Sigma’s Global Vision lenses are compatible with the company’s USB dock and Mount Conversion Service, and undergo individual testing before being shipped. Using the USB Dock allows for advanced customization of AF speed, OS viewing modes, focus limiter and firmware updates. Every Sigma Global Vision lens is tested with Sigma’s proprietary “A1” MTF measuring system prior to shipping to ensure optimal performance and image quality.
Sigma Corporation exhibited these lenses at the prestigious 2014 Photokina in Cologne, Germany, in September this year. The latest lenses from the Global Vision lineup were on display at the event.
