Review

The Sigma 45mm F2.8 DG DN Contemporary lens is a compact prime lens designed specifically for full-frame mirrorless cameras using the L-Mount. Known for its superb optical quality and versatile focal length, this lens is part of Sigma's Contemporary line, which aims to balance high-performance optics with portability.

Build and Design

One of the standout features of the Sigma 45mm F2.8 is its sleek and lightweight design. Weighing in at just 215 grams (about 7.5 ounces), it is an excellent choice for photographers who prioritize a compact setup. The lens is constructed with a combination of high-strength polycarbonate and metal, offering durability without adding unnecessary bulk. Its 55mm filter thread further enhances its versatility, allowing you to use a variety of filters for creative effects.

The lens boasts a classic aesthetic with its understated design, including a smooth, well-damped focus ring that allows for precise adjustments. The overall ergonomics are geared towards comfortable handling, making it an ideal companion for street, travel, and everyday photography.

Optical Performance

When it comes to image quality, the Sigma 45mm F2.8 does not disappoint. Sharpness is excellent across the frame, with minimal distortion and vignetting. The lens features a complex optical formula that includes multiple high-performance elements, such as aspherical and low dispersion glass, which work together to minimize aberrations. This results in vivid colors and exceptional contrast, giving images a professional quality.

The f/2.8 maximum aperture provides a decent shallow depth of field, allowing for pleasing background blur while still being bright enough for everyday shooting in various lighting conditions. While it may not be as fast as f/1.4 lenses, the Sigma 45mm is versatile enough for general use without being overly bulky.

Autofocus Performance

Equipped with a fast and silent stepping motor, the autofocus system on the Sigma 45mm F2.8 is noticeably quick and accurate. The lens locks focus almost instantaneously, making it suitable for capturing fleeting moments. The autofocus performance holds up well in both still photography and video applications, providing smooth continuous focusing for dynamic scenes.
