Sony FE 40mm f/2.5 G Lens

With a focal length occupying the sweet spot just between wide and normal, the FE 40mm f/2.5 G is an attractive prime for street, portrait, and landscape photographers alike. An excellent candidate for everyday carry, its compact profile and lightweight design are barely noticeable once attached to a camera. Extra-low dispersion and aspherical elements are used to minimize distortions and ensure sharp capture, while Nano AR II coating suppresses flare and ghosting. Two XD linear motors keep AF quick and quiet. Despite its small size, a de-clickable aperture ring, AF/MF switch, and customizable focus hold button are all incorporated into the lens barrel for tactile control.

Applications: This is a solid option for photographers looking for an everyday prime on the wide end of the spectrum.
