Sigma 800mm F5.6 EX DG HSM

Nikon F (DX/FX)

Review

The Sigma 800mm F5.6 EX DG HSM is an extremely powerful telephoto lens designed for Nikon F (DX) mount cameras. Its impressive focal length makes it perfect for wildlife, sports, and other distant subjects, allowing photographers to capture detail that would otherwise be lost. This lens is built for serious photographers who need to bring their subjects closer while maintaining image quality.

One of the standout features of the Sigma 800mm is its fast Hyper Sonic Motor (HSM), which ensures quick and quiet autofocus performance. This is particularly advantageous when shooting fast-moving subjects where timing is crucial. The lens also features a well-constructed build, with a solid and durable exterior that can withstand various shooting conditions. Its relatively compact design for such a long focal length also makes it more manageable for handheld shooting than one might expect.

In terms of image quality, the Sigma 800mm F5.6 performs admirably. It produces sharp, vibrant images with pleasing contrast. The lens's optical design includes special low dispersion (SLD) elements that help control chromatic aberration and enhance overall image quality. Additionally, Sigma's multi-layer coating reduces flare and ghosting, further elevating the performance in challenging lighting situations.

However, there are a few noteworthy drawbacks to consider. The aperture of f/5.6 can be limiting in low-light conditions, necessitating higher ISO settings or slower shutter speeds to maintain exposure. This can lead to noise in images, especially on DX cameras that are less capable in low light. Furthermore, the lens is relatively heavy, making handheld shooting a challenge over extended periods. A sturdy tripod or monopod is often required for optimal results.
