When Markus Varesvuo went on a shoot with the Canon EOS-1D X Mark III on its release in February 2020, he decided to push the camera's capabilities to the limit. He wanted a technically challenging situation in which spectacular results depended not only on photographic skill, but also on the camera being capable of meeting that challenge.
As a wildlife photographer who has been specialising in bird images for more than 40 years, Markus knew that shooting birds of prey flying at high speeds can be tricky. What's more, if you're photographing species that are most active in the evening and at night, then the twin challenge of a fast-moving subject and very low light makes it difficult for any camera to capture them in sharp, high-quality, low-noise images.
So, he packed a kitbag that included a Canon EOS-1D X Mark III body, together with Canon EF 400mm f/2.8L IS III USM and Canon EF 600mm f/4L IS III USM lenses, and headed for remote forests in eastern Finland and Finnish Lapland in search of demanding subjects.
Here, Markus talks about the species he photographed, the obstacles he faced and how the kit performed in the field.
