Nikon F (DX/FX)

Review

The Sigma 24-70mm F2.8 EX DG HSM is a versatile and widely respected standard zoom lens designed for Nikon F mount cameras, specifically in the DX format. This lens has become a staple for many photographers, thanks in part to its broad focal range, constant f/2.8 aperture, and solid build quality.

Build Quality and Design

Right out of the box, the Sigma 24-70mm F2.8 EX DG HSM impresses with its robust construction. The lens barrel feels durable, and its weight is substantial, providing a reassuring heft that speaks to its reliability. The zoom and focus rings are well-textured and smooth, allowing for precise adjustments while shooting. However, it’s worth noting that this lens does not feature weather sealing, which may be a concern for those who intend to shoot in harsh conditions.

Optical Performance

In terms of optical quality, the Sigma 24-70mm holds its ground well. Images produced by this lens are sharp across the frame, even wide open at f/2.8. This is particularly useful for portrait photographers wanting that nice depth of field and subject isolation. There is minimal distortion at the wide end, and chromatic aberrations are well controlled, although some noticeable fringing might occur in high-contrast scenarios.

Autofocus

The lens includes Sigma's HSM (Hypersonic Motor), which delivers quick, silent autofocus performance. This makes it suitable for both still photography and video work. While the autofocus is impressive, in low-light situations, the lens may struggle to lock focus as quickly as some competitors.

Versatility

The 24-70mm range is often considered one of the most versatile focal lengths for a variety of shooting scenarios—from landscapes and street photography to events and portraits. The constant f/2.8 aperture provides ample light for indoor shooting and low-light conditions, thus making this lens a reliable companion in various environments.
