Review

The Sigma 15mm F2.8 EX DG Diagonal Fisheye is a distinctive lens that offers a unique perspective through its impressive field of view and creative capabilities. Designed specifically for Canon EF mounts, this lens is a favorite among photographers looking to add eye-catching effects and a sense of immersion into their work.

Design and Build Quality

The Sigma 15mm F2.8 boasts a sturdy build with a professional feel. The lens barrel is constructed from durable materials, enhancing its longevity and resistance to the rigors of day-to-day shooting. The compact design makes it easy to carry, while the slightly bulbous front element adds to its character, albeit at the cost of being more prone to flare and scratches if not handled carefully.

Despite its fisheye designation, it’s important to note that this lens is not excessively large or heavy, making it suitable for frequent use without causing fatigue. The provided petal-shaped hood helps control flare and enhances contrast, which is a handy feature, especially in challenging lighting conditions.

Optical Performance

When it comes to optical performance, the Sigma 15mm F2.8 delivers impressive results. With a maximum aperture of f/2.8, this lens performs quite well in low-light situations; it allows for a quicker shutter speed, making it advantageous for shooting indoors or during dusk. The image quality is sharp, with minimal distortion for a fisheye lens. Colors tend to be vibrant and true-to-life, which is essential for landscape and architectural photography.

One of the highlights of this lens is its capability to create creative effects through distortion. You can achieve stunning perspectives that can add flair to your compositions. However, it’s essential to be mindful of the distortion, as it can be overwhelming if not utilized intentionally, especially in portrait photography.

Autofocus and Usability

The autofocus system on the Sigma 15mm F2.8 is reasonably quick and accurate, though it may struggle slightly in low-light situations or when photographing fast-moving subjects. Manual focus override is smooth, which allows for more creative control when required.

The focus distance is exceptionally close, allowing for intriguing macro-like shots that embrace the world up close. This versatility can be particularly appealing for photographers looking to explore various niches with a single lens.
