Sigma 135mm f/1.8 DG HSM Art Lens (Nikon F)

Engineered for professional portraiture and selective focus work, the Sigma 135mm f/1.8 DG HSM Art Lens delivers exceptional optical performance through its sophisticated lens design. The incorporation of FLD and SLD glass elements effectively suppresses chromatic aberration, ensuring pristine image fidelity across the frame. Super Multi-Layer Coating technology mitigates flare and ghosting while enhancing contrast and color rendition. The f/1.8 maximum aperture paired with a nine-blade diaphragm produces refined bokeh separation, enabling precise subject isolation. Ideal for photographers demanding superior resolution and refined optical characteristics in a fast telephoto format.

This telephoto prime incorporates a Hyper Sonic Motor for rapid, silent autofocus operation with seamless manual focus engagement. The robust construction employs Thermally Stable Composite materials, ensuring consistent optical performance across diverse environmental conditions. A precision brass bayonet mount delivers secure attachment and mechanical stability, critical for maintaining alignment during demanding shooting scenarios. Together, these engineering elements provide the reliability and responsiveness professional photographers require in field applications.

Key Features:

• As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
• Prime telephoto lens is designed for FX-format Nikon F-mount DSLRs, however it can also be used on DX models where it will provide a 202.5mm equivalent focal length.
• Bright f/1.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
• Two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
• A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
• Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.
• The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
• Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
• The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
• The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
