If you’re a professional photographer, you know that having the right lens can make all the difference when it comes to capturing the perfect shot. And when it comes to wildlife and sports photography, the Sigma 400mm f2.8 is one of the best lenses on the market.

The Basics

The Sigma 400mm f2.8 is a telephoto lens designed for use with both full-frame and APS-C cameras. It has a maximum aperture of f2.8, which makes it ideal for shooting in low-light conditions, and its 9-blade diaphragm produces beautiful bokeh.

Build Quality

One of the things that sets the Sigma 400mm f2.8 apart from other lenses is its build quality. It’s constructed from high-quality materials and feels solid in your hand. It’s also weather-sealed, which means it can withstand tough shooting conditions.


The autofocus on the Sigma 400mm f2.8 is fast and accurate, which is essential when you’re trying to capture fast-moving subjects. It also has a focus limiter switch, which allows you to limit the focus range and speed up autofocus even more.

Image Quality

Of course, the most important thing about any lens is the quality of the images it produces. And the Sigma 400mm f2.8 doesn’t disappoint. The images are sharp, with excellent contrast and color rendition. The lens also has minimal distortion and vignetting.

Tips for Using the Sigma 400mm f2.8

Use a Monopod or Tripod

The Sigma 400mm f2.8 is a heavy lens, and it can be challenging to handhold for extended periods. Using a monopod or tripod can help you stabilize the lens and get sharper images.

Shoot Wide Open

The f2.8 aperture on this lens is one of its main selling points, so make sure you take advantage of it. Shooting wide open will give you a shallow depth of field and beautiful bokeh.

Use the Focus Limiter Switch

As mentioned earlier, the focus limiter switch on the Sigma 400mm f2.8 can help speed up autofocus. Use it when you know the distance to your subject will be within a particular range.

Experiment with Different Shooting Modes

The Sigma 400mm f2.8 is versatile enough to use in a variety of shooting modes. Try using it in aperture priority mode to control depth of field, or in shutter priority mode to freeze motion.
