Performance Comparison

Image Quality

The Sigma 24-70mm f/2.8 DG DN Art and 28-70mm f/2.8 DG DN Contemporary offer distinct image quality experiences. The Art lens excels in sharpness, delivering consistent acutance from center to corner, especially when stopped down to f/4–f/8. It also provides excellent dynamic range, making it ideal for high-contrast scenes. The Contemporary model, while slightly softer at the wide end, maintains good sharpness in the mid-tele range. Its color science is vibrant but slightly less natural than the Art. Both lenses handle chromatic aberration well, though the Contemporary may require light correction in post.

Autofocus

In terms of autofocus, the 24-70mm Art lens delivers fast and precise focusing thanks to its advanced Hyper Sonic Motor (HSM). It excels in tracking moving subjects and supports reliable eye AF for portraits, making it a strong choice for action and wildlife photography. The 28-70mm Contemporary, while still quick, is slightly less refined, especially in continuous AF scenarios. It handles standard speed subjects well but may struggle with fast-moving targets. Eye AF is functional but not as refined, making the Art model preferable for more demanding autofocus situations.

Low-Light

Low-light performance is where the f/2.8 aperture shines for both lenses, but results vary slightly. The 24-70mm Art lens maintains better sharpness and contrast when shooting wide open, even in low-light conditions. It also handles background blur more naturally, which is beneficial for isolating subjects. The 28-70mm Contemporary, while still capable, shows a bit more corner softness at f/2.8. In high ISO scenarios, both lenses perform similarly, with minimal noise at ISO 3200–6400. However, the Art lens retains more detail in shadow areas, giving it a slight edge in low-light performance.

Video

For video, the Sigma 24-70mm Art lens is a strong contender for 4K and even 6K capture, with excellent resolution and minimal distortion. It supports modern video codecs and maintains consistent performance across the zoom range. The 28-70mm Contemporary is also capable of 4K recording but lacks the resolution depth and dynamic range of the Art model. It is not optimized for 8K and may show softness in certain focal lengths. The Art lens also features a more fluid and silent focusing motor, ideal for video work. The Contemporary is usable for vlogging and casual videography but falls short in professional settings.

Build Quality

Build quality is a significant differentiator between the two lenses. The 24-70mm Art lens is built to professional standards, featuring a weather-sealed body, metal lens mount, and durable materials. It is heavier and sturdier, ideal for harsh environments. The 28-70mm Contemporary, while well-constructed, is more lightweight and plastic-heavy, with limited weather protection. It is better suited for casual or travel use. The Art lens also includes a rotating front lens element, which is useful for filters. Both are well-balanced, but the Contemporary’s lighter weight makes it more comfortable for handheld shooting.

Verdict: Who Should Buy Which?

The Sigma 24-70mm f/2.8 DG DN Art is ideal for professionals and enthusiasts who prioritize image quality, sharpness, and performance in low light. Its optical excellence and robust build make it perfect for weddings, events, and studio work where precision and consistency are key. The Sigma 28-70mm f/2.8 DG DN Contemporary is better suited for everyday use, street photography, and travel. It’s lighter and more compact, making it easier to carry around without sacrificing too much in performance. The 28-70mm is especially useful for those who rarely use the 24mm wide end. If you’re a landscape or architectural photographer, the 24-70mm gives you more creative flexibility with its wider focal range. For vloggers or hybrid shooters who need a versatile yet compact lens, the 28-70mm is the better choice. Ultimately, your decision should be based on your shooting style and the need for either top-tier optics or portability.

Sigma 24-70mm f/2.8 DG DN Art

The Sigma 24-70mm f/2.8 DG DN Art is a high-performance standard zoom lens tailored for professional photographers and enthusiasts who demand optical excellence. Designed for full-frame mirrorless cameras, it features a 14-blade rounded aperture for smooth bokeh and consistent performance across the zoom range. The lens includes a 30-group, 21-element optical design with two SLD and three FLD glass elements to minimize chromatic aberrations and distortion. Real-world use, such as street photography or event coverage, benefits from its sharpness at f/2.8, especially when stopped down to f/4 or f/5.6. For example, shooting a portrait at 70mm f/2.8 with ISO 100 and 1/200s shutter speed delivers excellent detail and background separation. The lens is weather-sealed and features a high-quality focus motor for fast and silent autofocus, making it ideal for both stills and video.

While it’s slightly less sharp wide open at 28mm, it performs admirably when stopped down to f/4. For example, shooting a landscape at 28mm f/4 with ISO 200 and 1/60s shutter speed provides good detail and dynamic range. It lacks weather sealing but features a quiet stepping motor for video work. The lens is more budget-friendly and lighter, making it a great option for photographers who need a versatile all-rounder without the weight or cost of the Art series.

Lens Comparison: Sigma 24-70mm vs 28-70mm f/2.8 DG DN

When comparing the Sigma 24-70mm f/2.8 DG DN Art and the 28-70mm f/2.8 DG DN Contemporary, the differences in optical performance, size, and price are notable. The 24-70mm Art offers superior sharpness and edge-to-edge performance, especially at the wide end, while the 28-70mm Contemporary is more compact and lighter, with a slightly less ambitious optical design. The Art lens is ideal for professional use where image quality is paramount, while the Contemporary is better suited for travel or situations where portability matters. Both lenses share the same f/2.8 constant aperture and similar focal range, but the 24mm wide end gives the Art lens more flexibility for architecture or environmental shots. In practice, using the 24-70mm Art at 24mm f/2.8 with ISO 400 and 1/125s produces a wider field of view and shallower depth of field than the 28-70mm Contemporary. However, the Contemporary’s lighter build and lower price make it a compelling choice for casual and semi-professional users who don’t need the absolute top-tier optical performance of the Art line.
