Sigma 17mm F4 DG DN - Contemporary: The Ultimate Portable Ultra-Wide-Angle Lens

Sigma’s Most Portable Ultra-Wide-Angle Full-Frame Optic

Performance Meets Portability

Part of the renowned I series range of lenses in the Contemporary line-up, the Sigma 17mm F4 DG DN is one of the most compact full-frame ultra-wide-angle lenses available for mirrorless cameras. This lens features a retro-style, all-metal construction, including a metal petal-type hood, manual aperture ring, and metal focus ring, offering a premium and stylish feel. Despite its compact size, it delivers exceptional image quality across the entire frame, making it ideal for landscape, interior, wedding, and architectural photography. Photographers who prefer to travel light or carry their gear over long distances will find this lens particularly appealing.

Premium Build with Outstanding Image Quality

The Sigma 17mm F4 DG DN combines a sleek design with robust construction. Weighing only 225g, it is perfect for outdoor and travel photographers who need a compact yet durable lens that can be easily carried around all day. The lens features a dust- and splash-proof mount, protecting it from dust and water contamination. The tactile knurled metal lens hood, focus ring, and aperture ring enhance grip and control, while the included magnetic metal lens cap improves ease of use.

The 17mm F4 DG DN features a 55mm filter thread, the same size as other lenses in the I series such as the 24mm F3.5 DG DN | C, 45mm F2.8 DG DN | C, and 90mm F2.8 DG DN | C. This makes it easy to swap filters between lenses and reduce the overall weight of your kit. Additionally, the lens boasts an exceptionally close focusing distance of just 12cm, allowing for detailed close-ups without the need for a dedicated macro lens.

High-Performance Optics

Despite its compact size, the Sigma 17mm F4 DG DN does not compromise on optical quality. Its advanced design includes 9 elements in 8 groups, with 3 aspherical elements and 2 SLD elements to minimize chromatic aberration and maintain sharpness. Vignetting is minimal even at wide-open apertures, an important feature for ultra-wide-angle lenses. The lens also features Super Multi-Layer coatings to reduce flare and ghosting, making it ideal for shooting in bright light conditions.

Well-Controlled Flare and Ghosting

The advanced Super Multi-Layer lens coatings ensure minimal flare and ghosting, even when shooting into bright light sources such as the sun. This makes the Sigma 17mm F4 DG DN perfect for capturing stunning landscapes with rich, vibrant colours and excellent contrast.

Close Focus Ability

Unique for an ultra-wide-angle lens, the Sigma 17mm F4 DG DN offers a minimum focusing distance of just 12cm and a minimum working distance (from the subject to the front of the lens) of just over 7cm. This results in a 1:3.6 magnification ratio, enabling photographers to capture detailed close-ups without needing a dedicated macro lens.

Two Portable Wide-Angle Options

The Sigma 17mm F4 DG DN is a superb choice for photographers seeking a high-performance, ultra-wide-angle lens that is small and light enough for everyday use. It is exceptionally portable, at half the length and weight of the Sigma 16-28mm F2.8 DG DN | C, though it lacks zoom functionality and an F2.8 aperture. This lens is perfect for those who prioritise portability and premium build quality without compromising on image performance.

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.
