Review

The Sigma 300-800mm F5.6 EX DG HSM is a super telephoto zoom lens that caters to wildlife and sports photographers looking for extended reach without sacrificing much on image quality. Designed for the Canon EF mount, it brings a world of possibilities to those who need to capture distant subjects with precision.

Build and Design

At first glance, the Sigma 300-800mm is an imposing piece of equipment. Weighing approximately 6.3 kg (14 lbs) and measuring around 18 inches long, this lens requires a robust tripod or monopod for stability during use. The solid build quality and weather-sealed construction make it reliable for use in various conditions, whether you’re in a humid rainforest or a windy sports stadium. The matte black finish gives it a professional appearance and helps to reduce reflections from the sun.

Optical Performance

Optically, the lens performs admirably across its focal range. The F5.6 maximum aperture is consistent throughout the zoom range, allowing for suitable light gathering even in challenging conditions. The lens is equipped with multiple low-dispersion elements, which significantly minimize chromatic aberrations. Photographers will appreciate the sharpness in the center of the image even at 800mm, though some softness can be observed at the edges, especially in the corners at maximum zoom.

The lens also features Sigma's Hyper Sonic Motor (HSM) system, providing fast and near-silent autofocus. This makes it an excellent choice for wildlife enthusiasts who do not want to startle their subjects. The focus speed is generally impressive, though some users may find it struggles a little in low light when tracking fast-moving subjects.

Usability

When it comes to usability, the Sigma 300-800mm lens can be a mixed bag. The sheer weight and size make it cumbersome for handheld shooting; thus, a sturdy tripod is a must. The tripod collar is a beneficial feature, allowing for smooth panning when tracking subjects. Additionally, the zoom ring provides a decent amount of resistance, enabling precise adjustments, although some may prefer a smoother action.

Pros and Cons

Pros

• Exceptional reach with a versatile zoom range of 300-800mm.
• Good optical quality, particularly at the center.
• Fast and quiet autofocus thanks to HSM.
• Weather-sealed construction for better durability.

Cons

• Weight and size make it cumbersome for handheld photography.
• Softness in the corners at maximum zoom, which may require post-processing.

Verdict

In conclusion, the Sigma 300-800mm F5.6 EX DG HSM for Canon EF mount is a strong contender for anyone serious about wildlife and sports photography. Its impressive range and optical quality are complemented by solid build construction. However, the significant weight and some optical compromises at the edges may deter photographers looking for a more portable solution. Overall, if you’re willing to invest in the necessary support equipment and can handle the bulk, this lens will certainly elevate your photography game.
