Sigma 135mm F1.8 DG HSM Art Lens for Sigma SA

Sigma 135mm F1.8 Art: Mastering Portraits and Telephoto Precision

Overview:

The Sigma 135mm F1.8 DG HSM Art stands out as a top-tier prime telephoto lens, perfect for Sigma SA-mount cameras. This lens is a game-changer in the 135mm category, highly sought after by professional photographers and serious hobbyists for its unparalleled optical quality, rapid aperture, and beautifully rendered bokeh. Its advanced optical structure, incorporating FLD and SLD glass elements, ensures razor-sharp images, vibrant colors, and striking clarity, even at maximum aperture. The lens's f/1.8 aperture, coupled with a 9-blade rounded diaphragm, produces exceptionally smooth and creamy bokeh, making it ideal for portrait, product photography, and subject isolation. Durability is a key feature, with its dust- and splash-proof build, allowing it to perform flawlessly in various shooting environments. The Hyper Sonic AF motor provides fast, silent autofocus, essential for capturing spontaneous moments. The 135mm focal length offers a flattering perspective for portraits and effectively compresses backgrounds, enhancing the visual impact of your compositions. This lens is not just a tool but an artistic ally for photographers aiming to elevate their craft in portrait and telephoto photography.

More Details:

• Unrivaled Image Quality: Advanced optical design with FLD and SLD glass elements ensures sharp, clear, and color-accurate images, even at wide apertures.
• Mesmerizing Bokeh: The f/1.8 aperture and 9-blade rounded diaphragm create smooth, creamy bokeh, perfect for portraits and product photography.
• Robust and Reliable: Dust- and splash-proof construction makes it durable for challenging shooting environments.
• Rapid and Silent Autofocus: Equipped with a Hyper Sonic AF motor for quick, quiet focusing, capturing every moment with precision.
• Ideal for Portraits: The 135mm focal length offers a flattering perspective and background compression, enhancing the visual impact of your shots.

• Optical design delivering ultra-high-resolution and minimized chromatic aberrations - In addition to optimized power distribution, this lens features two SLD (Super Low Dispersion) glass elements and two FLD (“F” Low Dispersion) glass elements. These technologies help minimize chromatic aberrations, which tend to appear in the bokeh area outside of focus in portraits, as well as on slender objects such as fine branches.
• Image quality optimal for ultra-high-megapixel DSLRs - To deliver the ultra-high resolution that brings the best out of 50MP or higher ultra-high-megapixel DSLRs, the focus mechanism features SIGMA’s floating system. No matter what the distance from the subject, this lens offers top performance from the center to the edges of the image.
• Exclusive low-dispersion glass - Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. 
• Designed to minimize flare and ghosting - SIGMA’s Super Multi-Layer Coating helps further reduce flare and ghosting and provides sharp, high-contrast images even in backlit conditions.
• The large HSM delivers highly responsive autofocus - Delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. Along with the optimized AF algorithm, this feature delivers fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.
• Fast AF with full-time manual focus - Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.
• Mount with Dust and Splash Resistant Structure - The lens mount incorporates rubber sealing* to protect the mount from dust and water drops.
• Rounded diaphragm - The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
• High-precision, rugged brass bayonet mount - The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
