Conclusion

It's been a long time coming, but thankfully the new Sigma 70-200mm zoom for mirrorless has been well worth the wait - this is one of the best 70-200mm lenses that we've ever tested, and is especially appealing for L-mount camera owners.

Sporting a lighter, more compact design, a newer, faster auto-focus system, much more effective image stabilisation and more external controls on-board including the surprise addition of an aperture ring, it's clear that this is not just a straight conversion of the 2019 DSLR lens with a new mount.

It's tack-sharp at the centre of the frame and at the edges when stopped down by one-stop, with performance never dropping off throughout the focal range. Obvious vignetting at wide-open apertures and some mild distortion at either end of the zoom range are the only real optical issues of note, although these can both be easily corrected in post-production.

Auto-focusing proved to be very quick, accurate and reliable on the Sony A7C II camera that we tested the lens with, whilst the built-in optical image stabilisation system that's worth up to an impressive maximum of 7.5 stops proved to be a real boon on such a far-reaching lens.

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 and padded case included.

Even the price of the Sigma 150-600mm Sports is very attractive, significantly undercutting its main rival, the Sony FE 70-200mm F2.8 GM OSS II, and not too much more than the comparable Tamron 70-180mm F/2.8 Di III VXD. On L-mount, the Panasonic Lumix S PRO 70-200mm F2.8 O.I.S. is, as with the Sony, almost double the price.

There are a few quite important caveats with this lens for Sony users to be aware of. Firstly, it isn't compatible at all with teleconverters on the Sony system, secondly, it can't be used at the fastest burst rates on cameras like the Alpha 1 / A9 III, and finally the very useful USB dock isn't available for the Sony version.

They all might be very good reasons why you would choose the native Sony 70-200mm lens, for example, instead of this Sigma offering, although that particular lens is almost twice the price at £2600 / $2800 in the UK and USA.

Overall, the 70-200mm F2.8 DG DN OS Sports is an extremely high-quality addition to the ever-expanding Sigma range of professional lenses for Sony and particularly L-mount cameras.
