Independent lens maker Sigma has released Sony and Pentax-mount versions of its 18-250mm f/3.5-6.3 DC OS HSM lens.

Previously the lens was only available in Sigma, Canon and Nikon fits.

Priced £559.99, the zoom includes Hybrid Optical Stabilisation which is designed to allow photographers to use the lens’s OS function even if the camera to which it is attached has built-in anti-shake.

Features also include four Special Low Dispersion elements and three aspherical elements.
