Sony is expanding its series of G lenses for full-frame cameras to include three fixed focal lengths: the Sony FE 50mm F2.5 G (model name SEL-50F25G), the FE 40mm F2.5 G (model name SEL-40F25G), and the FE 24mm F2 .8 G (model name SEL-24F28G). These lenses are aimed at both still photographers and video shooters.
Designed for Sony Full Frame E-mount system, all three lenses weigh around 170 g, which is indeed quite light. They accept 49 mm front filters. They are also resistant to dust and moisture to a certain extent. The three lenses are all the same size (2.68″ diameter x 1.77″).

Sony 24mm F2.8 G prime lens
This lens is the “slowest” of the three, sporting a f/2.8 aperture, while the other two offer a faster f/2.5. It consits of 9 elements in 9 groups, including three aspherical lenses and one ED (extra-low dispersion) element to suppress chromatic abberations.
Sony 40mm F2.5 G prime lens
This one sits between a classic 35mm prime lens and the “nifty fifty” 50mm focal length. It sports 9 elements in 9 groups, including three aspherical lenses to suppress abberations and deliver high resolution. This lens does not offer an ED element like the other two.
Sony 50mm F2.5 G prime lens
The last one of these new compact lenses is the 50mm f/2.5 G prime lens. This lens consists of 8 elements in 7 groups but this time with two aspherical elements and one ED element.
