Sigma 100-400: Mountain Bikers, Big Horn Sheep

Ah, there’s a story today from Sigma that’s right up my alley….

Sigma Pro Liam Doran takes the 100-400mm C lens through the desert & chases mountain bikers & bighorn sheep.

The results are as stunning as you’d expect.

Meanwhile, David Schloss had the 100-400 with him last month at PressCamp, shooting…mountain bikers and landscapes for his Digital Photo Pro review.

What Liam Doram and David found with the Sigma 100-400 is the lens was still fast enough to lock focus on these riders despite the layout of the trail.

And, at 800.00 on Amazon it’s a steal; especially, when connected to the MC-11, and a Sony body like the a9.
