- 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.
- Optical Design
- 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.
- Circular Aperture
- 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.
