Action and wildlife photographers should choose the 70 – 400mm f/4-5.6 G lens with its improved autofocus performance and enhanced optics. Fast-moving objects can be moved much more efficiently with the enhanced tracking AF. On the other hand, the Carl Zeiss Planar T* 50mm f/1.4 ZA SSM lens will nicely close the gap between 24mm and 85mm prime lenses used by A-mount cameras.
