Good to know

This lens is designed specifically for Sony E-mount APS-C cameras; it will mount on full-frame bodies but will produce a cropped image circle. The autofocus is driven by a linear stepping motor, ensuring smooth and silent operation for video recording. While the lens itself lacks optical stabilization, many Sony APS-C bodies include in-body image stabilization (IBIS) that can compensate. The included lens hood helps reduce flare and protect the front element.
