Image: Sigma Sigma has announced the 300-600mm F4 DG OS Sports lens, designed specifically for applications like sports, action and wildlife photography. Optically, the lens is built around 28 elements in 21 groups. It includes 6 FLD and 1 SLD element, anomalous dispersion glass, high refractive index glass, and a water and oil-repellent front coating. It's designed to provide a high level of correction for chromatic aberration throughout the entire zoom range. Sigma claims the new zoom will deliver the same optical performance as a prime lens. Autofocus is driven by a high-thrust HLA (high-response linear actuator) motor that drives a lightweight lens focus group located close to the camera body for good balance and fast and precise AF performance. The image stabilization system provides 5.5 stops of stabilization at 600mm. It includes two stabilization modes: Mode 2 is designed to be widely used for most still and video applications and Mode 2 is designed specifically for panning shots in the horizontal, vertical or diagonal directions. The lens barrel is constructed from magnesium alloy, and the lens hood is made of carbon to deliver a sturdy but lightweight design. It's painted with thermal insulation paint to reduce heat absorption. The inner zoom mechanism is designed to minimize center of gravity fluctuations throughout the entire zoom range. The lens also includes a newly added function ring that offers two modes. With the Focus Preset Mode, twisting the ring right or left will instantly shift to a pre-registered focus position. The Power Focus Mode is intended to make it easier to focus the lens at a constant speed for applications like video and supports two steps; focus speed can be changed in two steps, depending on how far the ring is turned. Other controls include four AFL buttons, a focus mode switch, a focus limiter and OS mode switch and a custom mode switch. The L-mount version is also compatible with teleconverters. There is a drop-in holder for 40.5mm filters. According to Sigma, it has developed a new drop-in circular polarizer and a variable ND filter with 7 stops of adjustment to use with the lens. Sigma says the lens is dust and splash-resistant. The lens is 167mm (6.6") in diameter by 467.9mm (18.4") long. It weighs 3,985g (8.79lbs) The Sigma 300-600mm F4 DG OS Sports lens will be available from April 2025 at a retail price of $6000.
