A lens for special requirements. (40mm)

This particular series of lenses was sorely missing from Sony. Compact (almost like a pancake), incredibly light and quite fast in focusing.
It is mainly aimed at amateurs, but also hobbyists/enthusiasts.

The image quality is excellent and does not lag behind any of the other prime lenses in the G series.

With an aperture of f2.5, it is not the brightest, but now the capabilities of Sony cameras at higher ISO help you "cover" those few stops. It also has satisfactory Bokeh.

This lens is ideal for street photography due to its size. Also for everyday casual/family photography.
But I believe that even in portraits (especially if someone gets the 50mm) will be quite satisfied.
