The Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Sony E-mount cameras is a compact and lightweight standard zoom lens designed specifically for APS-C mirrorless systems. Ideal for everyday photography, this versatile lens combines professional-level performance with portability, making it a perfect match for content creators, travel photographers, and hobbyists alike. With a constant f/2.8 aperture, fast autofocus, and high optical quality, it meets the demands of both still shooters and video creators.
Fast Constant f/2.8 Aperture
One of the standout features of this lens is its bright constant f/2.8 aperture across the entire zoom range. This allows for better performance in low-light conditions, easier background separation, and more consistent exposure control, regardless of the focal length. Whether you’re shooting portraits, indoor events, or street scenes, the wide aperture ensures vibrant, sharp results with beautifully blurred backgrounds.
Versatile Standard Zoom Range
Covering an 18-50mm focal length range (equivalent to approximately 27-75mm in full-frame), the lens is extremely adaptable. It’s suitable for a wide variety of shooting situations—from wide-angle landscapes and group shots to medium-telephoto portraits and detail-oriented close-ups. This makes it an ideal all-around lens for travel and everyday use.
Exceptional Optical Quality
Engineered with 13 elements in 10 groups—including one Special Low Dispersion (SLD) element and three aspherical elements—the lens minimizes chromatic aberrations, distortion, and spherical aberrations. The result is clear, high-contrast images with excellent sharpness across the frame. Sigma’s Super Multi-Layer Coating further reduces flare and ghosting, even in challenging lighting conditions.
Compact, Lightweight Design
Weighing only about 290 grams (10.2 oz), the 18-50mm f/2.8 is incredibly lightweight and easy to carry, especially compared to other lenses with similar specs. It maintains a compact footprint that pairs well with Sony’s smaller APS-C bodies, offering excellent balance and handling, particularly for travel or on-the-go shooting.
Smooth and Fast Autofocus
Powered by a fast and silent stepping motor, the autofocus system performs exceptionally well in both still and video applications. It delivers quick, accurate focusing with minimal noise, which is especially valuable when recording video or shooting in quiet environments.
Close Focusing for Creative Flexibility
The lens also offers a minimum focusing distance of just 12.1cm at the wide end, enabling macro-like capabilities and allowing for impressive close-up shots with shallow depth of field. This feature opens up creative possibilities for food, product, and nature photography.
Durable Build and Practical Features
Constructed with a thermally stable composite (TSC) material, the lens offers reliable performance across a range of temperatures. The mount is made of durable brass, and the overall build maintains Sigma’s high standards of quality. While not fully weather-sealed, it does offer some resistance to dust and splashes, making it suitable for light outdoor use.
