Long awaited and highly anticipated, Sony has finally released an ultra-wide-angle prime lens for its full-frame mirrorless cameras: the FE 20mm f/1.8 G. While this company’s standard wides and normal-length lenses have been a focus and priority over the years, the ultra-wide sector has been relegated to zoom lenses—until now. With this new 20mm f/1.8, though, a more compact and focused design gives photographers and videographers a faster option, with advanced optics and intuitive handling, for wide-angle shooting.
This 20mm f/1.8 lens is Sony’s first full-frame prime lens that is wider than 24mm and, as such, is its first especially compact ultra-wide lens that features a bright f/1.8 maximum aperture. This faster, sleeker design greatly benefits astrophotographers, as well as hikers, landscape photographers, and even architecture and interior photographers because it’s a highly nimble and flexible lens for various scenarios. In terms of optics, a pair of Advanced Aspherical elements help to control spherical aberrations and distortion to achieve high sharpness, while a trio of ED elements suppresses chromatic aberrations for notable color accuracy. A Nano AR coating also reduces flare for color consistency when working in bright and backlit conditions.
In regard to handling, a dual XD Linear Motor system affords quick and quiet focusing, while linear manual focus response offers more tactile feedback when focusing the lens manually. A physical aperture ring is featured, too, and can be de-clicked to suit video applications. Additionally, the lens is dust and moisture resistant to enhance its suitability for working in most outdoor conditions. A fluorine coating is featured on the front element to make it easier to clean.
