Conclusion

The Sigma 150-600mm f/5-6.3 DG DN OS Sports offers a unique and high-quality alternative to similar lenses from Sony and Tamron, and in our view it's currently the best all-round super-zoom telephoto lens for Sony Alpha shooters.

Neither of those companies have a lens in their line-ups with exactly the same focal range - the Sigma 150-600mm's nearest competitors are the Sony FE 200-600mm f5.6-6.3 G OSS, which isn't quite as wide whilst being slightly slower too, and the Tamron 150-500mm F5-6.7 Di III VC VXD, which isn't as long at the telephoto end and again slightly slower in terms of its maximum aperture.

Build quality is excellent, with the brass lens mount and sober all-black design adding to the high-quality feel and the dust/splash-proof construction adding some peace of mind, plus there's a very good lens hood, shoulder strap and padded case included.

It is a pretty heavy lens that you won't want to hand-hold for too long, though, and therefore perhaps best suited to life on a tripod/monopod, although its significantly lighter than the DSLR version.

Auto-focusing proved to be reliably quick and quiet on the Sony A7 III that we tested the lens with, and the new Zoom Torque switch and the dual push/pull zooming design are great features, as is the effective built-in optical image stabilisation system.

The Sigma 150-600mm for Sony is tack-sharp at both the centre and edges of the frame when stopped down by one-stop at all the focal lengths, with performance still really high even at 600mm. Obvious vignetting at wide-open apertures is the only real optical issue of note, and this can be easily corrected in post-production.

Even the price of the Sigma 150-600mm Sports is very attractive, significantly undercutting the main rival lenses from Sony and Tamron (in the UK at least) whilst offering greater zoom range, lots of features, snappy auto-focusing and outstanding image quality.

Overall, we can whole-heartedly recommend the new Sigma 150-600mm f/5-6.3 DG DN OS Sports as an incredibly versatile telephoto zoom lens that delivers excellent results on full-frame Sony mirrorless cameras.
