Sigma has two 150-600mm zoom lenses in their lineup. One is in their Contemporary series: the Sigma 150-600mm f/5-6.3 DG OS HSM | C. It’s smaller, lighter, and cheaper. It’s designed to be a bit more portable, although it’s still not what you’d call pocket-sized by any means.
The one I’m focusing on here is in their Sports series: the Sigma 150-600mm f/5-6.3 DG OS HSM | S. The series name aside, it’s particularly aimed at shooting not only sports but also wildlife, action, and other fast-moving subjects.
It’s significantly heavier than the Contemporary version and has much improved optical performance. And you pay for that better optical performance–it’s over double the price of the Contemporary. It’s also less convenient to carry around. But plant it on a monopod in a good vantage point, and it’ll bring the action much closer and give excellent results.
I have a more detailed review of this lens here. But here’s a collection of images I’ve taken with this lens. Despite the Sports in its name, this lens is also a good option for more varied subjects. Although, being bigger and heavier than the Contemporary version, it’s slightly less convenient to carry around. I aim to add some more images here before long. But hopefully, it gives at least some sense of how the lens performs under real-world shooting conditions.
These were all shot in RAW and processed in Lightroom.
