Ultra-telephoto power in a compact package /
Designed specifically for mirrorless cameras, this versatile ultra-telephoto zoom is ideal for professional sports, wildlife, aviation and motorsport photography. Sitting in Sigma’s Sports line-up, the lens has a dust- and splash-resistant structure and a special water and oil-repellent coating on the front element, so is well-suited to use in outdoor environments.
The lens’s sophisticated optical design, which is made up of 25 elements including 4 FLD elements and 2 SLD elements, delivers exceptional image quality, with razor-sharp results at all apertures with very minimal chromatic aberration and well-controlled flare. The wide F5-6.3 maximum aperture ensures fast shutter speeds in low light and a shallow depth-of-field to help isolate the subject.
The lens boasts an impressive feature-set, including intelligent two-mode Optical Stabilizer, a rotatable tripod socket, a torque zoom function, three AFL buttons, two custom modes, a focus limiter and dual action zoom. This combination of powerful optics and advanced features makes the 150-600mm one of the versatile and popular ultra-telephoto mirrorless zooms on the market.
Outstanding build quality /
The exterior barrel of the 150-600mm is constructed of aluminium alloy and a polycarbonate called Thermally Stable Composite (TSC), which are both strong and light and expand or contract at the around same rate as temperatures change. The use of these materials is carefully optimised to maximise durability and strength while keeping weight to a minimum.
The zoom and focus rings are rubberised for easier operation, and the zoom ring can be locked at various positions using the Zoom Lock switch. The included lens hood is strong and light and has a rubber grip at the end for easy fitting and removal.
The 150-600mm DG DN sits in the Sports line-up, which means it is designed to withstand the rigours of heavy professional use. This includes a dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring and cover connection, allowing photographers to work in all types of weather.
At the rear of the lens is a tripod collar and foot for better balance when the lens is on a tripod, which can be rotated so that the camera can easily be switched between portrait and landscape orientation when mounted on a tripod. The foot has an Arca Swiss dovetail notch so that it will mount on an Arca Swiss compatible tripod without the need for a tripod plate.
The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.
Professional feature-set /
A range of controls on the lens include an AF/MF switch, an AFL button, and Optical Stabilizer switch, and a Custom Mode switch so that the lens set-up can be customised.
The lens also has a Focus Limiter so that the focusing range can be reduced for faster and more accurate operation. This is particularly useful when there are objects in the frame between the camera and the subject that the lens might attempt to focus on.
Introduced to this lens is the Zoom Torque function, which allows photographers to change the resistance of the zoom ring. The ‘S’ setting has minimal resistance for easier zooming – ideal for photographers using push-pull zoom – and the ‘T’ setting has more resistance. The ‘L’ setting locks the zoom ring at a range of focal lengths.
Dual Action Zoom means photographers can zoom with the zoom ring for accuracy, or by pushing or pulling the end of the lens for speed. The push-pull functionality is very useful for fast moving subjects.
The Optical Stabiliser has a mode for general shooting and one for panning – ideal for fast-moving birds and vehicles. With the OS2 firmware update, the lens offers a massive 6.5 stops at the wide end and 5.5 stops at the telephoto end.
