28mm E-mount fixed lens and Fisheye converter
- E-mount Full Frame format
- A convenient wide angle prime
- Dedicated optional converters available
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.
A 9-blade circular aperture works with this lens’s large aperture to produce smooth, beautiful background bokeh.
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.
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.
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.
A precision linear actuator built into the lens drives the focusing mechanism smoothly and quietly, and inner focus means that the lens does not extend while focusing. Quiet operation and stable handling are significant advantages when shooting movies.
A design the resists the intrusion of dust and moisture enhances reliability in harsh environments, letting you shoot with confidence wherever you go.
