With a DxOMark Score of 22 points, the Sony made, Zeiss designed Sony Vario-Sonnar T* 24-70mm F2.8 ZA SSM is the highest performing zoom in the range, followed closely by the Sony 70-200mm f/2.8G and Tamron SP 24-70mm f/2.8 Di USD sharing second place with 21 points.
At $499, best value of all the standard zooms analysed was the Tamron SP AF 28-75mm f/2.8 XR Di LD Aspherical [IF]. Although it lacks the ultrasonic type motor of the $1299 Tamron SP 24-70mm F/2.8 Di USD Sony version it achieves a DxOMark Score of 20 points, just 1 point less than the new model. It’s also worth noting that neither of these lenses (nor in fact any A-mount lens) features stabilisation as the SLT cameras adopt a built-in stabilised sensor platform.
As for telephoto zooms, the new Sony 70-400mm F4-5.6 G SSM II performs well but the model that really stands out is Sony 70-300mm F4.5-5.6 G SSM. If you can do without the extra reach at $800, it’s some $1,400 less and is nearly as good optically.
