Product Overview

Sony FE 40mm F2.5 G is a mid-range, ultra-compact prime lens for Sony's E-mount mirrorless cameras. The first Sony FE lens in its focal length, the SEL40F25G joins the FE 50mm F2.5 G and FE 24mm F2.8 G introduced at the same time as a trio of ultra-compact lenses with a premium build.
Unlike previous ultra-compact lenses released by Sony, the new 40mm is constructed of a full metal body with full sealing against dust and moisture. Like other recent Sony G series of prime lenses, the 40mm F2.5 G features a customizable focus hold button, an aperture ring that can be de-clicked, and an AF/MF switch.
While its maximum aperture at f/2.5 is hardly groundbreaking, the SEL40F25G is engineered to be sharp from f/2.5.

Reviewers from sonyalpha have found the following***:
The Sony is the best lens in term of size, sharpness, resistance to flare, ergonomics, build quality. The only area were other score better is for portraits with better bokeh balls/background blur when they offer a F1.2/F1.8 aperture and/or a longer focal length. The main limitation for portrait is the modest aperture of F2.5 for a 40mm that does not allow to have important background blur. If your usage is more portrait then the or will be a better choice.

Pros
  • Very high quality and balanced behaviorSharpness is excellent wide open even on A7RIV. Bokeh Balls, background blur, color rendition are very good wide open
  • Excellent build quality and ergonomics
Cons
  • F2.5 for a 40mm that does not allow to have important background blur

, both from their closest manually-focused distances and their maximum apertures. Zooming-in on the middle section shows there’s no problems in terms of resolving fine detail at the maximum aperture. As you focus the lens closer, the field of view reduces noticeably, an artefact that I’ve seen on a number of Sony lenses. In terms of autofocus for movies, the 40 2.5 is smooth, quiet and confident. Meanwhile the Sigma 45 2.8 works pretty seamlessly for face and eye tracking.

Pros
  • Sharpness across the frame even wide-open
  • Easy to use
  • Compact and compact
Cons
  • Focus breathing could be better

The FE 40mm F2.5 G is a fine addition to Sony's ever-expanding library of mirrorless lenses. It's sharp, focuses close, and draws photos with pleasingly defocused backgrounds. There are some drawbacks: controls are a bit cramped, focus breathing is a little limiting for video, and bokeh is not quite G Master quality.

Pros
  • Sharp, focuses close, and draws photos with pleasingly defocused backgrounds
  • Compact, light build
  • 5-axis stabilization
Cons
  • Focus breathing is a little limiting for video

Sigma 35mm f/2 DG DN Contemporary Lens is a great little metal-constructed lens. It should challenge the Sony G lens at comparable apertures. In the wide-open aperture image quality comparison, the Sony lens holds a center of the frame sharpness advantage.

Pros
  • Excellent image quality
  • Compact design
  • Excellent build quality
Cons
  • Small aperture blades
  • Small focus ring
