SIGMA 45mm F2.8 DG DN

Contemporaryoptimaler - Balancing everyday usability and performance

• Newly developed line of high-performance lenses for mirrorless full-frame cameras
• Beautiful bokeh and rendering, a pleasure with any subject
• Fast and highly accurate AF thanks to stepper motor
• High build quality and excellent operability

Designed for use on relatively small full-frame mirrorless cameras, this standard lens aims for ease of use as a regular fixed focal length, where portable size and high optical performance are optimally balanced. As such, the lens embodies the Contemporary product line's development concept of "striving for optimal balance" and becomes the perfect first lens in the product line for full-frame mirrorless cameras.

About the product designation: the product designation includes "DG" when the lens is designed to deliver its peak performance on cameras with full-frame sensors, and "DN" when the lens design is optimized for short-frame mirrorless cameras.

The SIGMA 45mm F2.8 DG DN Contemporary produces a particularly expressive bokeh. Spherical aberration has been controlled to ensure that not only the large bokeh in front of and behind the subject, but also the rear bokeh near the focus area create a smooth blur. This lens softly reproduces the out-of-focus peripheral areas by suppressing the double-line bokeh, etc., and enhances the three-dimensional effect of the subject by smoothing the foreground and background. In addition, the close focus limit of 24 cm enables snapshots and tabletop photography with creative use of the angle of view. The design takes vignetting into account to achieve a nice round bokeh while taming swirls in the overall bokeh.

While this lens produces a soft bokeh that can be described as "classic" when the aperture is wide open, it also achieves a modern, sharp rendition when stopped down further. This lens represents a reliable tool for everyday photography.

This lens offers smooth, quiet and fast AF thanks to a stepper motor and supports face detection/eye detection AF as well as video AF. The design takes MF operation into account, and a ring with optimized torque adjustment ensures good operability.

Since the lens is made for everyday use, special attention has been paid to build quality and operability. The bayonet hood feels comfortable to take off and put on, and the metal lens barrel as the main component achieves improved durability. Furthermore, the aperture ring with the right click feel ensures comfortable operability in different shooting situations.
