Covering some 70,000 square miles, South America's Pantanal region is the world's largest tropical wetland, and has the highest concentration of wildlife on the continent. This makes the national park and UNESCO World Heritage site a magnet for wildlife photography, where conservation-focused nature photographers such as Canon Ambassador Thorsten Milse can track down big players such as jaguar and caiman, along with capybaras, black howler monkeys and colourful macaws and toucans.
On his fifth trip to Brazil's biodiverse Pantanal region, Thorsten spent 15 days in the jungle and on the waterways in search of the wetland's largest predators and Red List endangered species – jaguar, ocelot and giant otter.
This time, he took the Canon EOS-1D X Mark III, Canon's new flagship action camera, keen to take advantage of its low-light capabilities when photographing nocturnal hunters, and to put the autofocus system to the test on fast-moving wildlife.
"The Pantanal has some special animals living in it," says Thorsten. "The main actor is the jaguar, the biggest predator in South America. It's an endangered species, but there's a really healthy population here, so it's easier to find them to take photos."
Each day, Thorsten spent the morning cruising the expansive river system, searching for the big cats, which stalk the shallow riverbanks around noon when potential prey like capybara and caiman are resting in the heat. "For the photographer, that's not perfect light, as the sun is directly over your head," he says. "It's also really hot – if you don't protect your camera, it gets burning hot."
During these blazing daylight hours, it can be hard to see clearly on a camera screen, so Thorsten needs his cameras to have an immersive and accurate viewfinder that's good at blocking out external light sources. "The EOS-1D X series cameras have some of the best viewfinders on the market," he says. "You see exactly what you will take."
In addition to scorching temperatures of up to 40°C, high humidity and tropical rainstorms, working in the Pantanal also brings with it some more unusual challenges – particularly when photographing giant otters, speedy underwater swimmers adept at evading the lens.
"It's much easier if you get out of the boat, so you're on eye level with the otters in the water," says Thorsten, who frequently wades into the murky brown rivers. "You need a really solid, weather-resistant camera. But if you have any cuts on your body, piranhas come. Sometimes they check your body – luckily I'm not very tasty!"
To track down ocelots, one of the area's most elusive predators, Thorsten headed inland deep into the jungle, setting up camp in a camouflaged hide close to a fresh water source in the cats' territory. In order to capture the shy, nocturnal animals in the dark, he set up LED lights in nearby trees to illuminate the scene without the need to use flash.
"Flash is a problem for all big cats," he explains. Their eyes are particularly prone to the animal counterpart of red-eye, reflecting green, orange or red. "It is much easier if you work with LED lights. You can also adjust the temperature and check the best white balance on your camera."
Even with LEDs, Thorsten needed to use a high ISO to capture the cats in action, which is where the new camera really stood out. "With my Canon EOS-1D X Mark II, the maximum ISO I would shoot to get the quality needed for a coffee table book was, in my opinion, ISO6400. On the Canon EOS-1D X Mark III I took the same quality images at ISO25600. That's two more stops that I can take really perfect photos with."
Even at ISO25600, using a shutter speed of 1/125 sec gave Thorsten clear shots of the ocelots climbing through the trees, which can stand up alongside images taken in daylight. They are good enough quality for prints close to 2 metres in width for the eventual exhibition of his large-scale project about endangered wildlife around the world. Thorsten also took advantage of the Canon EOS-1D X Mark III's remarkable continuous shooting performance, capturing bursts of 400-500 RAW files using CFexpress cards in the camera's two card slots.
"With wildlife, most of the good shots are taken at twilight," he says. "You must take photos at ISO3200, ISO6400, ISO12800. You have definitely more images using ISO25600. For a long time, I would have got, out of 500 images, three or four at ISO6400 that were really sharp. Now I have hundreds."
To let in that little bit more light, Thorsten tends not to stick to the rule of thumb that, for sharp results, shutter speed should be set to at least the reciprocal of the focal length – so for a shot taken at 560mm, the shutter speed should be 1/560 sec or faster. The fact that he gets sharp images like those above at this focal length at 1/320 sec, or at 335mm at 1/125 sec, also shows the effectiveness of the Image Stabilization in his Canon IS lenses.
"The most important things for taking really good wildlife shots are ISO and AF tracking," says Thorsten. With a new AF sensor with 28 times more resolution than its predecessor, tracking has been given a significant boost on the Canon EOS-1D X Mark III, perfect for wildlife photographers requiring pin-sharp shots of moving subjects.
Thorsten was particularly pleased with the camera's new AF button, which allowed him to change the focus point while tracking faster than ever. "It is perfect," he says. "It's much faster than a dial button or the old joystick. You can change its sensitivity, and it's really fast – if an ocelot is jumping from the left to the right in one second, you can move the AF field as quickly as pressing a touchscreen. The button is sensitive and precise and makes it easier to track subjects in low light."
Thorsten was predominately shooting on his wildlife hero lenses, the Canon EF 600mm f/4L IS III USM and the Canon EF 200-400mm f/4L IS USM Extender 1.4x. When photographing jaguars and otters at distances of around 20 metres with these telephoto lenses, it was especially important for the tracking to remain accurate, in combination with burst shooting.
"If a jaguar is swimming, jumping into the water or marking its territory, you need a fast shutter speed and a really good AF system. With the Canon EOS-1D X Mark III, it's easier to track the subject in low light, especially with a telephoto lens, and get sharper photos in the end.
"If you use a Canon EF 600mm f/4L IS III USM lens at 20 metres then it's full frame. If you're shooting a burst, you only have a small space in your frame, so I know that if I take 20 shots, then one will be perfect. Now with the burst rates of 16fps with the viewfinder and 20fps in Live View, you never miss a shot."
