Beautiful bokeh and rendering that can be enjoyed in any scene

With the Sigma 45mm F2.8 DG Contemporary bokeh expressions are particularly prominent. The spherical aberration has been controlled so that not only the large bokeh at the front and rear of the subject, but also the rear bokeh near the focus area creates a gradient to a soft blur. This lens softens the edge of out-of-focus images, suppresses double-line bokeh, etc., and enhances the three-dimensional impression of the subject through the soft expressions in the foreground and background. In addition, the minimum focusing distance of 24 cm makes it possible to take snapshots and tabletop photos utilizing the angle of view. The design takes vignetting into account to achieve a nice round bokeh and dampen the swirling bokeh in the overall bokeh effects.

While this lens produces soft bokeh effects at wide open aperture that could be described as a "classic expression", it also realizes a modern sharp rendition at stopped down aperture. It is reassuring to hold this lens as a normal lens for everyday use.

High build quality and excellent operability

As this lens is intended for everyday use, special attention has been paid to build quality and operability. The lens barrel, the main part of which is made of metal material, ensures improved durability. Furthermore, thanks to the aperture ring with the right click feel, comfortable operability is guaranteed for different shooting styles. The design takes MF operation into account, and a ring with appropriate torque ensures good operability

. Internal focus system

To increase stability, this lens configuration uses movable internal lens elements that adjust the focus without changing the length of the lens barrel.

Stepping motor

The lens enables smooth, quiet and fast autofocus enabled by a stepping motor and supports face/eye detection AF as well as video AF.

Compatible with lens aberration correction

This function adapts to the optical characteristics of the lens and performs in-camera corrections of peripheral lighting, chromatic aberrations, distortions, etc. to further improve image quality

*Function only available on supported cameras. The available corrections or the automatic correction function may vary depending on the camera model.
*For cameras where the lens aberration correction is controlled with "ON" or "OFF" in the camera menu, please set all aberration correction functions to "ON" (AUTO).

Super Multi-Layer Coating

Sigma's proprietary Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections in the lens. All lenses in the current Sigma range are equipped with this original technology. With digital cameras, stray light and ghost images can also be caused by reflections between the image sensor and the lens surfaces. Here too, the Super Multi-Layer Coating of Sigma is highly effective and ensures images with excellent contrast.

Aperture ring

Aperture ring that allows the user to work intuitively

Focus mode switch

This switch allows you to switch the focus mode between AF and MF.

Linear focus / Non-linear focus (only for L-mount）

A method of focus movement of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotation angle of the focus ring during manual focusing. With "non-linear focusing", the extent of the focal point movement varies depending on the rotational speed of the focus ring. With linear focusing, the amount of focal point movement remains the same regardless of the rotational speed of the focusing ring if the angle of rotation of the focusing ring is the same.

Mount with dust and splash-proof structure

The lens mount is equipped with a rubber seal that protects the mount from dust and splashing water.

High-precision, robust brass bayonet mount

The brass mount combines high precision with a robust construction. The treated surfaces and increased strength contribute to the exceptional durability of the lens.

Rounded aperture

The polygonal shape of a conventional iris diaphragm makes out-of-focus points of light appear polygonal. A rounded iris creates rounded out-of-focus points of light when it is opened almost to the maximum aperture. This creates attractive bokeh effects in many situations, e.g. when photographing a subject in front of a blurred water surface from which light is reflected.
