Sigma Unveils 150-600mm Lens for FF Mirrorless Cameras

Available for Sony E-Mount and L-Mount cameras, the ultra-telephoto zoom lens will be available in late August.

Sigma Corp. has introduced the Sigma 150-600mm F5-6.3 DG DN OS | Sports, the first Sports-line lens designed specifically for full-frame mirrorless camera systems.

Available for Sony E-Mount and L-Mount cameras, the lens comprises 25 elements in 15 groups and includes a range of high-performance glass that ensures thorough control of different types of aberrations. This helps give images the resolution and clearest detail throughout the entire zoom range.

Through improvements to the optical and mechanical designs as well as extensive simulated testing, the lens has achieved high resistance to ghosting and flare. This helps ensure sharp, high-contrast images even in strong sunlight or in backlit conditions.

At the wide end of 150mm, the lens has a minimum focusing distance of 23". On the L-Mount, the use of two dedicated teleconverters will allow users to shoot with AF up to 1200mm. 

With an AF actuator controlled by a stepping motor, the lens combines fast and quiet autofocus with excellent tracking of moving objects. Furthermore, a high-precision magnetic sensor enables accurate positioning for fast and high-precision AF.

The OS function delivers effective image stabilization that offers an advantage of approximately 4 stops, ideal for handheld shooting at slower shutter speeds. It is possible to change the OS settings using the OS switch and Custom Mode switch to best suit the shooting situation. The lens has a Focus Limiter switch offering three-zone AF modification, which helps to speed up AF performance, and on the L-Mount it is possible to set a custom focusing limit via the Sigma USB Dock. The lens also has three AFL buttons to which users can assign various functions on the camera side depending on the camera model used.

A dust- and splash-resistant structure, combined with a water- and oil-repellent coating applied to the front element, gives users peace of mind even in a harsh shooting environment.

The lens features a Dual Action Zoom, which supports both straight zoom and ring zoom, allowing users to change the angle of view in a quick and intuitive way. In addition, there is also a new Zoom Torque switch, with which users can change the resistance of the zoom ring and lock it at the wide end, ensuring ease of zoom operation as well as elimination of zoom creep.

On the lens body there is a magnesium tripod socket attachable to an Arca Swiss-type clamp. The foot is removable and can be replaced with an optional lens foot (replaceable lens foot type) or mounted on a monopod.

The lens body uses parts made of aluminum and Thermally Stable Composite where they are most suitable. TSC is a type of polycarbonate with a thermal expansion rate similar to that of aluminum, ensuring the lens behaves consistently at different temperatures. 

Compared to the Sigma 150-600mm F5-6.3 DG OS HSM | Sports, a Sports-line lens designed for SLR cameras, the new lens is lighter by 27 ounces and shorter by 1".

The Sigma 150-600mm F5-6.3 DG DN OS | Sports lens will be available in late August and will list for $1,499.
