Sigma 45mm F2.8 DG Full-Frame Contemporary Lens with Metal Bayonet Hood (Black, Sony E Mount)

The full-frame compatible Sigma 90mm F2.8 DG Contemporary Lens in Black for Sony E Mount introduces fresh value to mirrorless cameras. Its outstanding optical performance, combined with a compact size that complements today's smaller mirrorless models, opens up new possibilities for achieving the perfect shot.

Exquisite Bokeh

The Sigma 45mm F2.8 DG Contemporary lens puts a strong emphasis on bokeh characteristics. Spherical aberration is managed to ensure that both the prominent bokeh in front of and behind the subject, as well as the rear bokeh close to the focus area, transition nicely into a soft blur. This lens minimizes the peripheral blur, reducing double-line bokeh and enhancing the three-dimensional feel of the subject with smooth transitions in the foreground and background. Additionally, with a minimum focusing distance of 24cm, it allows for enjoyable shooting of snapshots and tabletop photographs that utilize the lens's perspective. The design also addresses vignetting to produce beautifully round bokeh while minimizing swirly bokeh across the entire bokeh spectrum. At wide-open aperture settings, it delivers smooth bokeh often described as 'classical,' while stopping down achieves a modern sharpness. It's a comforting choice as a reliable lens for daily photography needs.

Superior Build Quality and Exceptional Usability

With everyday use in mind, special care has been given to both the build quality and usability of this lens. The lens barrel, primarily made of metal, enhances durability. In addition, the aperture ring provides a satisfying tactile response, ensuring easy usability across different shooting techniques. The design also considers manual focusing, with an appropriately weighted ring for optimal handling.

Aluminum Bayonet Hood

The lens hood, constructed from aluminum, matches the lens body material, resulting in high quality and rigidity. The knurling on the surface further enhances practicality.

Quick and Precise Autofocus

This lens features smooth, quiet, and rapid autofocus facilitated by a stepping motor, which effectively supports face and eye detection AF, as well as video autofocus.

Inner Focus System Using Movable Internal Lens Elements

To enhance stability, the inner focus system allows movable internal lens elements to adjust focus without extending the lens barrel's length.

Lens Aberration Correction Compatibility

In order to further improve image quality, this feature adjusts chromatic aberrations, distortion, peripheral lighting, and other issues in-camera while matching the optical properties of the lens.

Flare-Reducing Super Multi-Layer Coating

The Super Multi-Layer Coating effectively reduces flare and ghosting by minimizing reflections within the lens. In digital cameras, flare and ghosting can also arise from reflections between the lens surfaces and the image sensor, making multi-layer coating highly effective in ensuring images with exceptional contrast.

Aperture Ring and Focus Mode Switch

The purpose of the aperture ring is to facilitate intuitive operation. The focus mode can be changed from AF to MF by using the Focus Mode switch.

Dust and Splash Resistant Structure

The lens mount boasts rubber sealing that protects the mount from dust along with water drops.

Other Highlights

The lens features a rounded diaphragm, high-speed autofocus compatibility, and AF Assist support for Sony E-mount. It has a high-precision, durable brass bayonet mount. Supporting DMF and AF plus MF, it is designed to minimize flare and ghosting. Each lens undergoes Sigma's proprietary MTF measuring system and includes a magnetic metal lens cap. Crafted in Aizu, Japan.
