Review

The Sigma 85mm F1.4 EX DG HSM is a remarkable lens that has been well-regarded among portrait photographers and anyone seeking a high-quality prime lens for their Nikon F (DX) mount. Known for its bokeh and sharpness, this lens offers a unique combination of professional quality and versatility, making it a favorite in various photography genres.

Build Quality and Design

The build quality of the Sigma 85mm F1.4 is solid and robust, featuring a metal body that gives it a premium feel. The lens is relatively heavy, which can be a consideration for those who prefer lightweight gear for extended shooting sessions. It also includes a rubber seal around the mount, offering some degree of weather resistance, allowing photographers to use it confidently in various environments. The focus ring is smooth and well-damped, allowing for precise adjustments, which is particularly helpful in portrait photography.

Optical Performance

This lens excels in optical performance, showcasing impressive sharpness that remains consistent across the frame, even at wide apertures. The F1.4 maximum aperture allows for stunning shallow depth of field, making it easy to isolate subjects while creating beautifully blurred backgrounds. The lens also demonstrates excellent color rendition and contrast, which helps in capturing vibrant and lifelike images. Moreover, the HSM (Hyper Sonic Motor) ensures fast and quiet autofocus, which can be a vital feature for portrait sessions where capturing fleeting expressions is crucial.

Versatility

While designed primarily for portraits, the Sigma 85mm F1.4 is quite versatile and can be used for various types of photography, including events, weddings, and even some creative landscape photography. The 85mm focal length is especially appealing for those who enjoy a slightly compressed perspective, excellent for flattering portraits. It’s a beautiful lens for dramatic shots that require a mix of detail and isolation.

Low-Light Performance

Due to the wide aperture of F1.4, this lens performs admirably in low-light situations. It allows photographers to shoot handheld in dimly lit environments and still achieve good results without compromising on shutter speed or ISO noise. Many users have praised it for its ability to gather light without sacrificing sharpness, a notable advantage for evening and indoor events.

Autofocus Performance

The autofocus system of the Sigma 85mm is generally fast and reliable, thanks to the HSM. However, some users have reported occasional hunting in low-light conditions or complex scenes, which might require manual intervention. This is not a deal-breaker, but it’s worth noting for photographers who frequently work in challenging lighting situations.
