Sigma 45mm f/2.8 Contemporary DG DN Prime - L-Mount

The Sigma 45mm f/2.8 Contemporary DG DN Prime - L-Mount is designed for use with relatively small full-frame mirrorless cameras, achieving easy operability as a regular prime lens by balancing its compact size and high optical performance. This embodies the Contemporary line's core development concept of "pursuing optimum balance", making the 45mm f/2.8 the ideal first lens in a lineup dedicated for full-frame mirrorless cameras. 

A New Challenge

With mirrorless cameras emerging at an accelerated pace, expectations of lenses better suited to high-performance full-frame mirrorless cameras are increasing. Unfortunately, many photographers may feel that they have fewer choices for mirrorless lens systems in terms of performance, size, available features and focal lengths, and the burden of having to use multiple systems. SIGMA has subsequently developed this new full-frame mirrorless lens series as an optimal solution to this challenge.

SIGMA will continue to develop interchangeable lenses with unprecedented specifications and performance, utilizing designs that benefit from the short flange focal length of mirrorless cameras, while retaining the guiding concepts of "Contemporary", "Art", and "Sports" classifications.

Beautiful Bokeh & Image Rendering

With the SIGMA 45mm F2.8 DG DN | Contemporary, bokeh expressions are especially notable. Spherical aberration has been controlled to ensure not only the large bokeh in the front and rear of the subject, but also the rear bokeh near the area in focus, creating a gradient to a soft blur. This lens softens the periphery of blurred images, suppresses effects like the double-line bokeh, and enhances the 3D impression of the subject with smooth expressions in the foreground and background.

In addition, its minimum focusing distance of 9.4" (24cm) makes it possible to enjoy shooting snapshots and tabletop photos, taking advantage of the angle of view. The design gives consideration to vignetting to achieve beautiful round bokeh and subdue "swirly" bokeh in the overall bokeh effect. While this lens produces smooth bokeh effects one could call "classical expression" when the aperture is wide open, it also achieves modern, sharp rendering when it is stopped down. 

High-Speed, High-Accuracy Autofocus

The lens is capable of smooth, quiet, high-speed AF, thanks to a stepping motor, and supports both Face/Eye Detection AF and video AF. The design gives consideration to manual focus operations, and a focus ring with appropriate torque provides comfortable operability.

High Build Quality

Because this lens is intended for everyday use, particular attention has been given to build quality and operability. The bayonet hood feels comfortable when removing and attaching, and the lens barrel incorporates metal material to achieve improved durability. Furthermore, thanks to an aperture ring with a correct "click feeling", comfortable, tactile operability during various shooting styles is ensured.
