Sigma 135mm F1.8 DG HSM Art Lens: Fast Telephoto Prime for Unrivalled Artistic Expression
Optical Excellence with Stunning Bokeh
The Sigma 135mm F1.8 DG HSM Art lens is a full-frame mid-telephoto prime, celebrated for its exceptional optical quality, fast aperture, and robust build. As the longest prime lens in Sigma’s Art line-up, it’s perfect for portraits, weddings, events, and telephoto landscapes. The lens produces spectacular bokeh, allowing photographers to separate subjects from backgrounds with striking perspective compression.
Advanced Optical Design for High-Resolution Images
Featuring two SLD (Special Low Dispersion) elements and two FLD (F Low Dispersion) elements, the Sigma 135mm F1.8 minimizes chromatic aberration, even in high-contrast scenes, ensuring ultra-high resolution and clarity throughout the image. Its fast F1.8 aperture excels in low-light conditions, making it ideal for capturing stunning portraits.
Robust and Precise Construction
The lens boasts superb build quality, with a barrel made from Thermally Stable Composite (TSC). This material is strong, lightweight, and has a thermal expansion rate similar to aluminium, ensuring consistent performance in varying temperatures. The internal focusing mechanism and rubberised focus ring enhance ease of use, maintaining a constant lens length.
Ready for Any Environment
The Sigma 135mm F1.8 features a dust- and splash-proof construction, making it reliable for outdoor use. The robust lens hood reduces flare and ghosting in bright sunlight while protecting the front element. A durable brass mount with a rubber seal helps keep out dust and moisture.
High-Performance Optics
The advanced optical design includes 13 elements in 10 groups, ensuring razor-sharp results with minimal chromatic aberration, flare, distortion, and vignetting. A Super Multi-Layer Coating reduces flare and ghosting, delivering high-contrast images with rich colours and strong blacks.
Shallow Depth-of-Field Effects
With its F1.8 aperture and 135mm focal length, the lens creates a narrow depth-of-field, producing beautiful background blur and enhancing the separation between subject and background. This effect is more pronounced than with shorter focal lengths, adding a dramatic touch to portraits and other subjects.
