The Sigma 17mm f/4 DG DN Contemporary Lens is a lightweight and compact wide-angle lens designed for mirrorless cameras. It is part of Sigma’s Contemporary line of lenses, which are designed to be portable and versatile. One of the standout features of this lens is its size and weight. It weighs just 285g and is only 58mm in length, making it a great option for photographers who want a wide-angle lens that won’t weigh them down.

Another impressive aspect of this lens is its construction. It features a dust- and splash-proof design, which makes it suitable for use in challenging weather conditions. The lens also has a high-quality build, with a metal barrel and a smooth, precise focus ring.

Pros:
- Compact and lightweight: The lens weighs just 270 grams, making it easy to carry around and use for extended periods without fatigue.
- Great image quality: The lens produces sharp images with excellent color and contrast, even when shooting at wide apertures.
- Good build quality: The lens feels solid and well-built, with a metal mount and a weather-sealed design that provides protection against dust and moisture.
- Good value: The lens is reasonably priced for a wide-angle lens with this level of performance and features.
Cons:
- Slow maximum aperture: The f/4 maximum aperture is not particularly fast, which may make it less suitable for low-light shooting or situations where you need extreme bokeh the background.
- No image stabilization: The lens does not have image stabilization built-in, which may be an issue for handheld shooting in low light.
