Aug 11, 2021 ·  The Sony FE 40mm F2.5 G lens is a full frame lens, designed for the full frame mirrorless cameras such as the Alpha 7 or Alpha 9 series.

The FE 40mm is one of three new lenses from Sony, all with the same basic outward appearance. It sits in between the FE 24mm F2.8 G and FE 50mm F2.5 G in focal length, but all are housed in metal barrels, with (barely) enough room for hands-on controls. Overall fit and finish is excellent, which is expected from a G series lens. It's the branding Sony uses for midrange options, those better than basic, but not as high-end as the G Master (GM) lens series. The FE 40mm is a slim lens, though not quite a pancake.

Mar 23, 2021 ·  The Sony FE 40mm f/2.5 G has a slightly odd focal length that’s a little longer than the classic 35mm ‘street’ lens and shorter than a 50mm ‘standard’ lens. In practice, you quickly adapt to the focal length and it’s a pretty good blend of the qualities of both.
