Sigma 150-600mm f/5-6.3 DG OS HSM | S

Hefty but worth the weight

This Sigma Sports lens is around 1.5x to 2x the weight of most contenders on test, tipping the scales at nearly 3kg. Sigma also makes a smaller and lighter Contemporary edition of its 150-600mm lens, but this one is better built. The barrel and hood are metal rather than plastic, and features a full set of weather-seals.

Optical highlights include two FLD (Fluorite Low Dispersion) elements and fluorine coatings on the front and rear. Advanced features include dual autofocus modes, dual-mode stabilisation, and two switchable custom modes. The zoom lock can be engaged at any marked focal length.

Performance

All aspects of image quality are excellent, throughout the entire zoom range. Autofocus is very fast and the stabiliser works very well in both static and panning modes. It’s a fabulous super-tele zoom with suitably ‘sporty’ performance.
