Nikon F (DX/FX)

Review

The Sigma 70mm F2.8 EX DG Macro is a well-regarded option for Nikon F (DX) mount users looking to explore the world of macro photography. With its dedicated macro capabilities and solid build quality, it provides the potential for stunning close-up images, making it an attractive addition to any Nikon photographer's kit.

Build Quality and Ergonomics

One of the standout features of the Sigma 70mm F2.8 is its robust construction. The lens feels solid in hand, and the rubberized focus ring offers a smooth and tactile experience that allows for precise manual focusing—a crucial aspect when dealing with macro subjects. The lens also has a relatively compact design, making it manageable for extended shooting sessions.

Optical Performance

In terms of optical performance, the Sigma 70mm f/2.8 delivers impressively sharp images, particularly when stopped down. The lens is designed to provide excellent contrast and detail, even at its maximum aperture. Chromatic aberration is well-controlled for a macro lens, and bokeh quality is pleasing, with a smooth transition in out-of-focus areas. Keep in mind, though, that at very close distances, you may occasionally encounter some distortion, which is typical for macro lenses.

Focusing and Versatility

The autofocus system is quick and reliable, especially in decent lighting conditions. However, in low-light situations, it may struggle a bit, which could necessitate manual focus adjustments. Considering that most macro work occurs in close proximity to the subject, having the option for manual focus helps here. Additionally, the lens features a 1:1 magnification ratio, allowing you to capture fine details, such as the texture of a flower petal or the intricacies of an insect.

Compatibility and Use Cases

The Sigma 70mm F2.8 is primarily designed for macro photography but can also serve well in portraiture and general photography. Its focal length is ideal for getting a bit closer to your subject while still maintaining a comfortable distance. That said, it may not be the best lens for wide-angle shots or landscape photography due to its fixed focal length.
