Product Description

Introducing the Sigma 50-100mm F1.8 DC HSM | Art Lens

A Mid-Telephoto Crop-Sensor Zoom with Prime Lens Image Quality

Versatile Zoom with Prime Lens Quality

Designed for APS-C DSLRs, the Sigma 50-100mm F1.8 DC HSM | Art lens combines the convenience of a zoom with the image quality of a prime lens. Its complex optical design includes 21 elements, featuring 3 SLD and 4 FLD elements to minimise chromatic aberration at any aperture or focal length.

With a full-frame equivalent focal length of 75-150mm, this lens is ideal for various photo and video applications, including portraits, events, weddings, and wildlife. The constant F1.8 aperture ensures fast shutter speeds in low light and a shallow depth of field for striking, high-impact results. The lens is also part of Sigma’s high-speed zoom cine lenses lineup.

High-Precision Construction

The Sigma 50-100mm F1.8 DC HSM | Art lens showcases the superb build quality expected from an Art-line lens, featuring intuitive ergonomics and exceptional craftsmanship. The outer barrel is made from a Thermally Stable Composite (TSC), a polycarbonate that is strong, lightweight, and has a thermal expansion rate similar to aluminium. This ensures that both the interior aluminium parts and exterior TSC parts react consistently to temperature changes.

The lens features a rubberised focus ring for easy operation and internal focusing, meaning the lens does not change length during focus. A built-in tripod collar, which can be rotated, ensures a balanced setup when mounted on a tripod. The robust petal-type lens hood helps reduce flare and ghosting in bright sunlight and protects the front element from damage. The durable brass mount with a rubber seal keeps out dust and moisture.

High-Performance Optics

The advanced optical design of the 50-100mm F1.8 DC HSM | Art lens includes 21 elements in 15 groups, ensuring razor-sharp results with minimal chromatic aberration, flare, distortion, and vignetting. An advanced Super Multi-Layer Coating reduces flare and ghosting when shooting in bright direct sunlight, ensuring outstanding image quality right into the corners of the frame, even when shooting wide open at F1.8.

Ideal for Portraits

With its constant F1.8 aperture and mid-telephoto focal length, the Sigma 50-100mm lens is perfect for portrait photography. The smooth and attractive bokeh enhances the subject without distracting from it, creating beautiful, professional-quality portraits.

Understanding: Aperture

Aperture is the opening in a camera lens that controls how much light enters the camera. It's measured in f-stops like f/2.8 or f/8. Lower f-stop numbers mean wider openings, letting in more light and creating a shallow depth of field (blurry background). Higher f-stop numbers mean smaller openings, letting in less light and creating a larger depth of field (more of the scene in focus). Aperture also affects the quality of out-of-focus areas in the image (bokeh).

Understanding: Lens Types

Different lenses have different purposes to achieve different styles of images, some popular ones include:
Prime Lens: Fixed focal length, sharp images, great for portraits and dark settings.
Zoom Lens: Variable focal length, versatile for different shots and everyday use..
Wide-Angle Lens: Captures wide scenes like landscapes.
Telephoto Lens: Magnifies distant subjects, ideal for sports & wildlife.
Macro Lens: Perfect for close-up photography of small subjects.
Fisheye Lens: Ultra-wide perspective, creates unique images.

Understanding: Lens Mounts

Different camera brands use different lens mounts, which are like connectors that attach lenses to camera bodies. Each mount is specific to a particular brand and camera series. For example, Canon uses the EF and RF mounts, Nikon uses the F mount, Sony uses the E mount for its mirrorless cameras. These mounts dictate which lenses are compatible with which cameras. Some brands offer adapters to use lenses from other systems, but it's essential to ensure compatibility for proper functionality and autofocus performance.

Understanding: Manual and Autofocus

Manual focus and autofocus are two ways to adjust the sharpness of a camera lens. With manual focus, you turn a ring on the lens to bring the subject into focus yourself, giving you full control over what appears sharp in the image. Autofocus, on the other hand, relies on the camera's built-in technology to automatically adjust the focus for you, usually by detecting contrast or phase differences in the scene. Autofocus can be convenient, especially for fast-moving subjects or when you need to capture a quick shot, whereas manual focus allows for precise adjustments and creative control over the final image.
