Sigma 4.5mm F2.8 EX DC HSM Circular Fisheye

Nikon F (DX/FX)

Review

The Sigma 4.5mm F2.8 EX DC HSM Circular Fisheye is a unique lens that caters to photographers seeking to capture expansive landscapes, architectural marvels, and creative portraits with an artistic twist. Designed for Nikon F (DX) mounts, this lens provides an intriguing perspective thanks to its circular fisheye design.

The 4.5mm focal length offers a 180-degree field of view, creating a circular image that can be both mesmerizing and daunting to work with. The maximum aperture of F2.8 allows for decent low-light performance, making it suitable for various shooting conditions. The lens employs HSM (Hyper Sonic Motor) technology, ensuring fast and quiet autofocus, which is particularly beneficial when shooting in dynamic environments.

One of the standout features of the Sigma 4.5mm F2.8 is its optical quality. The lens incorporates several Special Low Dispersion (SLD) glass elements to minimize chromatic aberrations and distortions, delivering sharp imagery across the frame. Additionally, the lens has a durable build, making it ideal for outdoor photography.

However, working with a circular fisheye can pose challenges. The perspective can easily become exaggerated, leading to distortion that, while appealing in many contexts, might not suit every photographer's vision. Furthermore, the lens doesn’t have a traditional focus ring, reducing manual focusing accuracy which can be a drawback for those who prefer hands-on control over focus.

While it excels in optical performance and construction, the unique nature of its fisheye design requires careful consideration of the intended use. For photographers willing to embrace its eccentricities, this lens can produce stunning and imaginative results that challenge conventional perspectives.
