Sigma 18-35mm F1.8 DC HSM Art Lens: High-Performance Wide-Angle Zoom

The Sigma 18-35mm F1.8 DC HSM Art Lens is revolutionizing photography. Aimed at Blackmagic users and high-end camera enthusiasts, this lens is a part of the esteemed Art series. It shines with its F1.8 aperture. Photographers get great low-light performance and depth of field. This lets them create sharp images with beautiful bokeh effects, even in varied lighting.

This lens has advanced optics. It uses Special Low Dispersion glass and aspherical elements. These reduce chromatic aberrations and distortion. The result? Sharp, clear images that meet professional standards. The Hyper Sonic Motor makes autofocus fast, precise, and quiet. It’s perfect for shooting in nature or busy cities without causing a disturbance.

Built to endure, the Sigma 18-35mm F1.8 has robust construction and weather sealing. It’s great for outdoor use. The manual focus override allows for meticulous focus adjustments. Plus, the rounded diaphragm blades enhance the bokeh effect, giving a professional look to portraits and detailed shots.

The lens includes a customizable focus hold button. This button can be set for different functions, making the lens more user-friendly during shoots. Suitable for various types of photography—be it filmmaking, landscapes, weddings, or street scenes—the Sigma 18-35mm F1.8 offers versatility and top-quality image performance. It’s a standout choice for both new photographers and pros.

More details:

• 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.
• 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.
• HSM (Hyper Sonic 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.
• Incorporating an Inner 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.
• 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.
• Super Multi-Layer Coating - In digital cameras, flare, and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA’s Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.

Applications:

• Portrait Photography: The wide aperture allows for a shallow depth of field, creating beautifully blurred backgrounds that make subjects stand out.
• Landscape Photography: The wide zoom range from 18mm to 35mm is ideal for capturing expansive landscapes, providing both broad vistas and detailed close-ups.
• Street Photography: The fast aperture and responsive autofocus make it excellent for capturing dynamic street scenes, even in low light conditions.
• Event Photography: Its ability to handle varying lighting conditions without sacrificing image quality makes it perfect for weddings, concerts, and indoor events.
• Videography: The smooth and silent Hyper Sonic Motor (HSM) autofocus is beneficial for recording video, ensuring that focusing is quiet and does not disrupt audio capture.
• Night Photography: The lens’ exceptional low-light performance enables photographers to shoot after dark, capturing clear and sharp images of nightscapes and city lights.
• Travel Photography: Robust and weather-sealed, it’s built to withstand the rigors of travel, making it a reliable companion for capturing high-quality images on the go.
• Architectural and Real Estate Photography: The wide-angle perspective also serves well in capturing buildings and interiors, showing detailed compositions and the full scope of a structure.
