The new 28mm E-mount Nokton features outstanding optical performance using two Aspherical Elements with four Aspherical Surfaces and two abnormal Partial Dispersion lens. There are 10 elements in 8 groups. Even with a fast F1.5 aperture this new E wide angle is only 55mm long.

For Sony E-mount

The lens has electronic contacts to ensure that lens usage data is included in the Exif data of captured images. Furthermore, the built-in distance encoder enables support for 5-axis image stabilization on the body side. Other features include being able to magnify the finder display by operating the focus ring.

Optimized optical design

Provides an imaging circle that covers the 35 mm full frame format and utilizes an optical design optimized for Sony E-mount sensors. High resolution is maintained up to the image periphery and color shifts are well controlled.

Minimum focus distance of 0.28 meters

The minimum image capturing distance from the subject to the imaging surface is 28cm. This lens expands the possibilities for imaging utilizing the strong perspective characteristic of wide angle lenses.

12-blade aperture diaphragm for beautiful bokeh

The aperture diaphragm is configured with 12 blades to make the aperture opening as circular as possible. This means the out-of-focus areas of images are drawn naturally and point light sources etc. are drawn as soft round bokeh rather than as polygonal shapes.

Manual focus for reliable focus operation

Adopting a full-metal helicoid unit processed and adjusted with high precision and high-quality grease that produces an appropriate torque, focusing with a smooth operation feeling is realized. It enables fine focus adjustment.

Aperture click-stop switching mechanism

The aperture click-stop switching mechanism enables the aperture mechanism to be steplessly stopped down/opened up with no click-stop sound. This ensures that the sound of the aperture ring being operated is not recorded while capturing video and also enables a high level of depth of focus control by fine-tuning the aperture ring.
