Sony FE 40mm f/2.5 G Lens

Wide-Normal Portable Prime

A comfortable focal length with an especially portable design, the Sony FE 40mm f/2.5 G is a versatile prime; an ideal single focal length option for a broad variety of situations. This lens's smart build and sophisticated G Series optics mix with intuitive handling and the sleek form factor to make it a go-to option for anything from street to landscape to travel applications.

 

Matched Set of Compact Primes

Together with the FE 24mm f/2.8 and 50mm f/2.5 G lenses, these three lenses form a cohesive trio with similar styling, image quality, and ergonomics:

• All lenses prioritize a compact profile with an emphasis on intuitive handling; each features a manual aperture ring along with other tactile controls.
• The three lenses share the same 49mm filter ring diameter.
• Matched aluminum finish with stylish focal length and aperture engravings, both aperture and focusing rings, and matching metal lens hoods.

G Lens Series

• Three aspherical elements promote more uniform sharpness across the frame by suppressing spherical aberrations and distortions.
• Rounded 7-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.

Focus Control for Stills and Video

 

• Two linear motors deliver quick and accurate autofocus performance, along with capable subject tracking for working with fast-moving subjects. This AF system is also especially quiet to suit its use for cine applications.
• Internal focusing design limits the overall length of the lens for faster, more responsive focusing.

• Linear Response manual focus control offers more natural handling and an AF/MF switch is located on the lens barrel for tactile control over this setting.
• Customizable focus hold buttons are present on the lens barrel for intuitive tactile control and rapid access to select settings.
• Impressive close-up performance for working with close-up subjects; this lens has a minimum focusing distance of 9.8" with MF (11" with AF), which results in a 0.23x maximum magnification.

Sleek-but-Robust Design

• Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
• Lens measures 1.8" and weighs 6.1 oz, making it a great portable choice that's well-suited to both full-frame and APS-C bodies.
• Dust- and moisture-sealed design better permits working in inclement conditions.
• Fluorine-coated front element is easy to clean and resists dust, moisture, and fingerprints.
