The 60-600mm f/4.5-6.3 DG OS HSM Sports lens is described as ‘the absolute all-rounder’ and covers a 10x zoom range. Combining high ratio, high image quality, and high mobility with the lens construction of 25 elements in 19 groups, this lens delivers consistent image quality throughout the entire zoom range. It also incorporates Intelligent OS adopting the latest algorithm to deliver stabilisation of up to 4 stops. An updated algorithm ensures high-speed AF captures instantaneous photography movement. This lens is due for release in late October 2018 at an MSRP of US$1999. Pricing and availability have not yet been released for the other lenses.
Sigma also announced plans to produce a full-frame L-mount camera with a Foveon sensor as well as plans to allow existing users to adapt or convert SA mount lenses to the L mount as well as adapters for S to L-mount and Canon EF to L-mount. The company will cease production of cameras using the SA mount.
