Sony has issued firmware updates for nine of its E-mount lenses and the LA-EA3 adapter, most of which appear to be aimed at increasing lens performance when used with the new Sony a9 camera.
Three lenses – the Planar T* FE 50mm F1. 4 ZA, FE 85mm F1. 4 GM, and FE 70-200mm F2. 8 GM OSS – gain support for continuous, blackout free shooting at up to 20fps on the a9, one of the camera's headline features. The update for the 70-200mm GM also promises to improve startup speed when used with the a9.
Also important, the LA-EA3 adapter now enables adapted A-mount lenses to maintain continuous autofocus at up to 10 fps when used with the a9.
Finally, the updates improve AF stability and IRIS function during continuous shooting on several lenses.
