The 90g full-frame autofocus design and STM stepping motor make this 40mm f/2.5 a featherweight prime for Sony E-mount that delivers face and eye tracking without bulk. Its 9-blade aperture yields soft, bubbly bokeh, while the clicked aperture ring and one-touch AF/MF switch add direct, tactile control.
