The lenses are also claimed to offer a reduction in ghosting – especially with ‘tricky against-the-light shots’ – and faster AF performance.
Sony claims they can each deliver around four times the subject tracking speed of their predecessors.
The Vario-Sonnar T* 24-70mm f/2.8 ZA SSM II and Vario-Sonnar T*16-35mm f/2.8 ZA SSM II feature aspherical and extra-low dispersion elements to help minimise distortion.
The 16-35mm also includes Super ED glass.
There is as yet no word on UK pricing or availability.
Sony repeated its commitment to A-mount photographers at a presentation in central London this afternoon.
