Available in both Sony E-mount and Leica L-mount, this lens offers a unique blend of versatility and prime-like optical quality, making it ideal for creatives who demand high performance and flexibility in a single lens. Checkout our recent review!

It's perfect for photographers who value the prime-like optical quality of Sigma's Art series, combined with the convenience of a zoom lens. Videographers will also find this lens indispensable, especially those working with Sony or Leica systems, thanks to its internal zoom mechanism, customisable controls, and smooth aperture adjustments. If you require a fast aperture for low-light conditions or crave precise control over depth of field, this lens should be a serious contender for your kit.

Precision Engineering Meets Durable Design

The build quality of the Sigma 28-45mm f/1.8 is second to none, living up to the high standards of Sigma's renowned Art series. A robust, weather-sealed metal barrel ensures durability, and the inclusion of three control rings - focus, zoom, and aperture - along with two customisable buttons allows for seamless adjustments in any shooting environment. Notably, the internal zoom mechanism ensures the lens maintains its balance, a critical feature for videographers looking for smooth, uninterrupted transitions.

Uncompromising Optical Performance

Optically, this lens is a game-changer. Combining aspherical and low-dispersion elements, it delivers consistently sharp images across the entire zoom range while effectively controlling chromatic aberration and distortion. Even when wide open at f/1.8, the sharpness remains impressive, allowing for stunning subject isolation with beautiful, creamy bokeh that has become a hallmark of Sigma's Art lenses. Whether you're shooting stills or video, the lens offers a performance that rivals prime lenses.

Gain Fast and Silent Autofocus

The autofocus system is another area where the Sigma 28-45mm f/1.8 excels. Powered by Sigma's HLA (High-response Linear Actuator) focus motor, the lens offers fast, accurate, and virtually silent autofocus. It pairs perfectly with Sony's advanced autofocus systems, including eye-tracking, ensuring reliable performance across a variety of shooting scenarios. While nearly parfocal, videographers may experience slight abruptness in focus shifts during smooth transitions, though this is a minor tradeoff for the overall speed and precision offered.

Versatile Focal Range with Constant Aperture

While the 28-45mm focal range may seem unconventional, it proves surprisingly versatile, covering essential medium focal lengths. This makes it an ideal tool for photographers and filmmakers who regularly shoot within this range. The constant f/1.8 aperture is a key advantage, ensuring consistent exposure across the zoom range—crucial for low-light environments and for achieving a shallow depth of field without needing to adjust settings during a shoot.

Designed with Video Professionals in Mind

Sigma has thoughtfully integrated features designed specifically for video creators. The aperture ring, equipped with D-Click and Iris Lock options, allows for smooth, silent adjustments on the fly, making it ideal for on-set use. The additional customisable buttons on the barrel further enhance usability, offering quick access to frequently used functions and streamlining workflows for both photographers and videographers.

Comparison Amongst Others

When comparing the Sigma 28-45mm f/1.8 DG DN Art Lens to other options, it quickly becomes clear why this groundbreaking lens stands out. The Sigma 24-70mm f/2.8 DG DN II Art Lens offers a broader focal range, but its f/2.8 aperture doesn't match the f/1.8 speed that the 28-45mm delivers. For photographers and videographers who demand prime-like optical quality, especially in low light, the Sigma 28-45mm is the superior choice. Its faster aperture offers better subject isolation and depth of field control while maintaining Sigma's renowned sharpness and colour accuracy.

Similarly, while the Tamron 28-75mm f/2.8 Di III RXD G2 Lens offers affordability and a broader zoom range, it can't compete with the 28-45 mm's faster aperture and pro-grade build. The internal zoom, weather-sealing, and premium control rings on the Sigma make it the clear winner for serious creatives.

For Leica L-mount users, the Panasonic Lumix S Pro 24-70mm f/2.8 is a viable alternative at almost the same price point. Still, the Sigma's f/1.8 aperture takes the lead in delivering superior low-light performance and artistic depth. Overall, the Sigma 28-45mm f/1.8 DG DN Art Lens redefines what a zoom lens can achieve, offering unparalleled features over similar models.

Final Thoughts

When it comes to image quality, the Sigma 28-45mm f/1.8 truly stands out from the rest. Its sharpness, beautiful bokeh, and excellent control of aberrations make it an excellent choice for both photography and videography. Whether you opt for the Sony E-mount or the Leica L-mount, this lens is a solid investment for any professional or enthusiast looking to elevate their work.
