More Details:

• Exceptional Low-Light Performance: The lens's bright f/1.4 aperture ensures outstanding performance in low-light conditions, enabling beautiful bokeh effects and precise depth of field control.

• Superior Optical Quality: As part of Sigma's esteemed Art line, this lens is celebrated for its sharpness, minimal aberrations, and accurate color reproduction, ensuring top-notch image quality.

• Advanced Autofocus System: Equipped with a Hyper Sonic Motor, it offers quick, silent, and accurate autofocus, essential for capturing sharp images in various lighting conditions.

• Durable and Weather-Sealed: The lens is constructed with high-quality materials and is weather-sealed, offering protection against dust, moisture, and splashes, making it reliable for outdoor use.

• Compact and Lightweight Design: Despite its premium features, the lens remains relatively compact and lightweight, ensuring ease of handling and portability for photographers on the move.

• Additional Technical Features: Includes a 9-blade rounded diaphragm for smoother bokeh, Super Multi-Layer Coating to reduce flare and ghosting, Thermally Stable Composite construction for consistent performance, and a rear focusing system to minimize focus shift. It's also compatible with the Sigma USB Dock for firmware updates and fine-tuning adjustments.

• HSM (Hypersonic Motor) - Delivers high AF speed and extremely quiet performance. An optimized algorithm offers even smoother automatic focusing, and full-time manual focus override is another key feature.
• Rear Focus system - The lens incorporates a rear focus system that prevents focus-dependent variation in aberration, making high-level image quality possible throughout the entire image. With their unchanging barrel length, these lenses also enhance balance and stability for the photographer. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.
• TSC (Thermally Stable Composite) - A first for the industry, the barrel of the lens features a new TSC (Thermally Stable Composite) that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens. TSC also makes possible slimmer forms for parts like zoom rings and scaling rings.
• Rounded diaphragm - When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.
• Flare and ghosting reduction - SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high-contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
• 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.
