Review

The Sigma 10-20mm F3.5 EX DC HSM is a versatile ultra-wide-angle zoom lens designed specifically for Canon EF mounts. It is particularly favored by landscape photographers, architectural enthusiasts, and anyone looking to capture expansive scenes with remarkable clarity and detail. With its constant f/3.5 aperture, this lens delivers consistent performance throughout its zoom range, allowing for creative shooting in various lighting conditions.

One of the standout features of the Sigma 10-20mm is its impressive field of view, which allows you to capture sweeping vistas and tight spaces without distortion that can often plague ultra-wide lenses. The lens construction includes 13 elements in 11 groups, which helps produce sharp images while minimizing aberrations. The Hyper Sonic Motor (HSM) provides quick and quiet autofocus, making it an excellent tool for videographers as well. Additionally, its build quality feels solid and durable, making it suitable for outdoor photography sessions where the elements can play a part.

However, there are some drawbacks to this lens. While it excels in various conditions, it can produce a noticeable amount of barrel distortion at the extreme edges, especially when shooting architecture straight-on. Moreover, the lens is relatively bulky for an ultra-wide, which might be a concern for photographers who prefer a lighter, more compact setup. The f/3.5 maximum aperture may not be fast enough for low-light situations compared to other lenses in this category, thus limiting its versatility during evening shoots or indoor events.
