Wildlife rarely gives you a second take. That’s the lesson veteran photographer Daniel Cox keeps coming back to, and it’s exactly what saved his shoot last month when a pod of Pacific white-sided dolphins started springing into acrobatics off the coast of British Columbia, Canada.
With 40 years behind the viewfinder, Cox had his gear dialed in before the action began. The kit doing the heavy lifting: an OM System OM-1 Mark II paired with the OM System 150-400mm lens. Because it’s a Micro Four Thirds body, that 400mm reach effectively doubled to 800mm — and most of the jumping dolphins were shot at that full extension.
His settings tell a story of controlled speed. Cox worked in Shutter Priority at 1/2000 of a second, a figure he picked deliberately: the boat was rocking, and any animal that appeared would be moving fast. His rule of thumb is to shoot at least one stop above the focal length in use, which at an effective 800mm made 1/2000 the sensible floor.
He’s not precious about manual mode, either. Cox leans on auto ISO, letting the camera juggle aperture and sensitivity while he locks in the shutter speed that matters. For focus, it’s AF-C all the way — when a dolphin breaks the surface for just one or two seconds, continuous autofocus is the only realistic way to stay on it. He even zooms while firing, framing on the fly so the subject sits neither too tight nor too small.
Then there are the habits that no firmware can replace. Rule one, and Cox is dead serious: take the lens cap off and leave it off. He doesn’t own a single capped lens in his bag, protecting front elements instead with a Hoya HD3 skylight filter. He’s watched seasoned shooters raise a camera to their eye, see black, and lose the shot entirely.
To predict where the dolphins would surface next, Cox shoots with both eyes open — right eye on the electronic viewfinder, left eye scanning the wider scene for the next breach. It’s an awkward skill, but it lets you swing the lens toward the action instantly.
And no matter how good in-body stabilization has become, Cox insists good form still counts. On a pitching boat he becomes what he calls the Human Tripod: camera in the right hand, lens cradled in the left palm, both elbows pinned to the ribs, the body pulled tight against the forehead. Locked in like that, you’re as steady as a boat deck will ever allow.
The takeaway is refreshingly analog for such a capable camera. The OM-1 Mark II is fast, but the fastest tool in Cox’s bag is preparation. When something unrepeatable erupts out of the water, the only people who catch it are the ones who were ready the whole time.
