Sony SEL28F20 FE 28mm F2

Prime lens resolution and contrast : Advanced fixed focal length optics effectively minimize aberration from infinity right down to the closest focusing distance for excellent sharpness throughout the image area. All lens surfaces are multi-coated to minimize backlighting induced flare and ghosting for maximum subject clarity and contrast.
Smooth, expressive bokeh : A 9-blade circular aperture works with this lens’s large aperture to produce smooth, beautiful background bokeh.
Small and light for everyday photography : The compact, lightweight design of this full-frame lens is an ideal match for compact α7 series bodies. At only 200 grams it is a convenient choice for snapshots and everyday use, and an aluminum alloy exterior adds elegant appearance as well as sophisticated feel.
Dedicated optional converters go wider : Two optional, dedicated front converters conveniently expand the angle of view to 21mm ultra-wide and 16mm fisheye without degrading optical performance or visual appearance. A sensor system in the converters and lens ensures that appropriate EXIF data is generated when either converters is attached, for easy data management.
Explore prime lens performance : An ideal second lens for full-frame photographers who want to explore the superior sharpness and expressive potential of a high-performance prime lens. An optical design that includes 3 aspherical(one is an advanced aspherical element) lens elements and 2 ED elements packs outstanding optical performance into a compact lens, and a bright F2.0 maximum aperture makes low-light shooting easy.
