Among the people at Ocean Leisure cameras, Jussi Hokkanen is particularly keen on macro life. For example, our Finnish member of staff is crazy about nudibranchs, those colourful little seaslugs that wear their feathery gills on their backs. A keen underwater photographer, when he recently visited Manado in North Suluwesi to go diving, it would have been remiss of him not to make a pilgrimage from there south to Lembeh Strait, the critter capital of the world.
Lembeh Strait, the stretch of water between Pulau Lembeh and the busy port of Bitung, has had the dubious benefit of three thousand years of busy boat traffic with all the rubbish and detritus that only that could have brought with it. The seabed is a grey lava sand littered with rubbish but Nature being adaptive as it is has overcome all that human beings have thrown at it and creatures underwater have evolved in various ways. It may not sound very attractive but as the dive guides like to brief, “If you see a bit of rubbish, it’s probably an animal that looks like a bit of rubbish, but if it really is a bit of rubbish it will have an unusual animal living inside it!”
Of course, all these critters are in the main very small so Jussi took with him a suitable underwater camera rig that would allow him to record images of theses tiny animals that were usually bigger than life-size. He successfully photographed mandarin fish, a neon clam and a hairy frogfish among numerous other subjects.
For this he chose to use Olympus E-PL7 camera with the Olympus PT-EP12 Housing.
With the often bought 14-42mm zoom lens it represents remarkably good value at close to one-thousand pounds. However, for the macro life found at Lembeh Jussi preferred to use the Olympus 60mm macro lens, which he mounted behind an AOI Macro port. AOI supplies a range of different ports, both in acrylic and glass, that can be used in conjunction with the Olympus PEN housings. He then added an Inon UCL-165 wet lens
to the front. This combination gave him the close-up six-dioptre magnification he required. If he had needed even more magnification, he could have swapped to a twelve-dioptre AOI macro lens. To get his images recorded in a full spectrum of vibrant colour, Jussi needed to take some white light under water with him.
For this he chose to use two Inon S-2000 strobe lights (flashguns) triggered by twin fibre-optic cables from the flash attached to the camera. These are neat and compact and have heads small enough not to give light with too little contrast when positioned so close to the small subjects. These were mounted to the camera housing via a Nauticam Easy Tray with optional additional handle and short i-Das arms with standard one-inch mounting balls and clamps. To make it easier to see to focus on such tiny subjects Jussi added a Fisheye FIX Neo 1000 WR spotting light.
This little wizard of a lamp can be switched to a red mode so that the light it gives out does not disturb the animals. (Most marine life does not see red light.) Once Jussi had lined up his camera, the light pulsed from the strobe units gave him a full colour rendition. Not only that, but the focussing lamp automatically senses the flash firing and switches off momentarily so that there is no annoying spot remaining where the focussing light was pointed.
