Quick Answer
Choose the Sigma 28-70mm f/2.8 DG DN Contemporary if you prioritize a compact, lightweight walk-around zoom. Choose the Sigma 24-70mm f/2.8 DG DN II Art if you need the wider 24mm field of view and professional-grade image quality.
The Size and Weight Trade-Off
The most immediate difference between these two lenses is physical size. The Sigma 28-70mm f/2.8 DG DN Contemporary is designed to be a compact standard zoom, making it a strong choice for travel or all-day shooting. The Sigma 24-70mm f/2.8 DG DN II Art is larger and heavier, but that extra bulk brings a wider angle at the short end and a more robust build.
Focal Length and Versatility
The 24mm wide end of the Art lens gives you a noticeably wider field of view compared to the 28mm start of the Contemporary. That 4mm difference matters when you're shooting in tight interiors or capturing expansive landscapes. The Contemporary's 28-70mm range is still very versatile but will require you to step back more often.
Image Quality and Autofocus
Both lenses feature a constant f/2.8 aperture and use advanced optical elements. The Art lens uses Sigma's flagship design with high-performance optics and a high-speed autofocus motor, making it a top choice for professional portraits and events. The Contemporary lens still delivers very good sharpness and uses a stepping motor AF system that is quiet and responsive for most shooting situations.
Key Trade-Offs at a Glance
- Size & Weight: The 28-70mm Contemporary is noticeably smaller and lighter, making it better for travel and everyday carry. The 24-70mm Art is larger and heavier but offers a wider zoom range.
- Wide-Angle Coverage: The Art lens starts at 24mm, giving you a 4mm wider field of view than the Contemporary's 28mm. This can be critical for indoor or architectural shots.
- Autofocus Performance: The Art lens features high-speed AF for fast, quiet focusing. The Contemporary uses a stepping motor system that is also quiet and responsive, but not as fast as the Art's system.
