Full Frame E-mount. As a part of the FE line of lenses, the 55mm f/1.8 is designed to cover the full-frame sensors on Sony E-mount cameras. Since it’s an E-mount lens, it’s also fully compatible with APS-C NEX cameras.

Normal Range. When used on a full-frame camera, this lens provides a moderately wide focal length that’s great for landscape, street, and portrait photography. With an APS-C sensor camera, you’ll have a short telephoto length of about 83mm—perfect for portraiture. The fast f/1.8 aperture is great for low-light shooting and subject-background isolation.

Internal Focusing. The lens remains the same size while it’s focusing. Its non-rotating front element allows for improved filter use.

Advanced Optics. The FE 55mm f/1.8 uses three aspherical elements to reduce spherical aberrations and produce sharp, clear images. The Carl Zeiss T* anti-reflective coating eliminates lens flare and ghosting while providing the famous high micro-contrast Zeiss look. The lens’s curved nine-blade aperture diaphragm gives images smooth out-of-focus areas when you desire a shallow depth of field.

High Build Quality. Like the Sony a7-series cameras, the FE 55mm offers dust- and moisture-resistant sealing for use in less-than-ideal conditions. The all-metal barrel and smooth, responsive manual-focus ring give this lens a solid feel.
