(Open Box) Sony FE 40mm f/2.5 G - E-mount Camera Lens

The Sony FE 40 mm f/2.5 G is a versatile prime lens engineered for Sony’s full-frame E-mount mirrorless systems. Its 40 mm focal length delivers a natural field of view that sits between classic 35 mm and 50 mm perspectives — making it exceptional for street photography, documentary, landscapes, portraits, and everyday use.

Featuring a maximum aperture of f/2.5, the lens balances low-light capability with a compact design, while a rounded 7-blade diaphragm delivers smooth and pleasing bokeh when shooting with selective focus. The optical formula consists of 9 elements in 9 groups with multiple aspherical elements to control aberrations and ensure sharp, high-contrast results across the frame.

Autofocus performance is fast, accurate, and quiet, driven by Sony’s advanced internal AF system, and the lens includes a physical aperture ring with a de-click switch that’s useful for video work. Dust and moisture sealing adds durability for outdoor use, and a fluorine-coated front element helps repel dust and oils.

The FE 40 mm f/2.5 G offers a minimum focus distance of about 0.28 m (0.92 ft) and a maximum magnification of ~0.23×, making it capable of working close to subjects for creative compositions. It’s also lightweight (~173 g) and compact, accepting 49 mm front filters, making it a superb walk-around lens for photographers and videographers alike.
