Compact Prime Lens for Mirrorless Cameras
This full-frame 28mm wide-angle prime lens is an excellent choice as a second lens. It features a bright F2 maximum aperture and outstanding overall optical performance. Advanced optics and coatings with a 9-blade circular aperture deliver beautiful images. A fast and linear internal focusing actuator makes this lens ideal for both still and movie applications.
When changing the aperture to defocus the background, the light sources will appear blurred. This "bokeh" effect of the blurred background can be enhanced by the circular aperture blades used in this lens. Conventional aperture blades have flat sides, creating unappealing polygonal-shaped defocused points of light. However, this lens overcomes this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. The result is smoother, more natural defocusing.
As focal lengths get longer, lenses built with conventional optical glass can struggle with chromatic aberration, leading to lower contrast, color quality, and resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, providing superior contrast across the entire image, even at large aperture settings. Super ED glass provides even further compensation for chromatic aberration.
Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is caused by differences in refraction at different points on conventional spherical lenses, which can degrade image quality in large-aperture lenses. Specially shaped "aspherical" elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture. Aspherical elements can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.
The internal focusing design means the overall length of the lens does not change during focusing. Other important benefits include fast autofocusing and a short minimum focusing distance. Additionally, the filter thread at the front of the lens does not rotate, which is convenient when using a polarizing filter.
For even wider perspectives, optional Ultra-wide Converter (SEL075UWC) and Fisheye Converter (SEL057FEC) lenses can be added to increase the angle of view to 21mm wide-angle or 16mm fisheye with full 180° coverage, respectively. Corresponding EXIF data is generated when these converters are attached, making data management easy.
This lens is a perfect match for the α7 series of 35mm full-frame E-mount cameras, delivering outstanding optical performance in a wide 28mm focal length with a bright F2 maximum aperture.
