Wide-Angle Prime Lens for Full-Frame E-Mount Cameras
This 28mm prime lens is designed for full-frame format E-Mount mirrorless cameras and is also compatible with the APS-C format cameras on which it provides the 35mm focal length equivalent of a 42mm lens. Its f/2 maximum aperture is effective in low light and enables shallow depth of field control.
Aspherical and Advanced Aspherical lens elements reduce spherical aberration and multi-coated Extra-low Dispersion glass elements minimize chromatic aberration and reduce ghosting and flare for sharper images with more contrast.
Internal Focus and Linear Actuator Autofocus Mechanism
Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient if you're using a polarizing filter. The linear actuator AF system provides smooth and quiet AF action.
A unique 9-blade design keeps the aperture almost perfectly circular. Smoother, more natural out-of-focus highlights can be obtained as a result.
Compact, Robust Form Factor
At less than 2.5" long, this 28mm lens is a ideal companion for mirrorless E-Mount cameras and its dust and moisture resistant seals allow it to be used in less than ideal conditions.
