Lumix Coolpix Triggerfish

Whenever we do the yearly Bluescope seagrass monitoring trip to Westernport I take the tweaked Coolpix 5000 housing with the Lumix LX3 fitted. Jan always likes to spice up her report with some photos of the colourful marine life under the wharfs.

It's not worth taking the SLR rig and I think the compact setup is better for the difficult conditions. Currents and terrible vis are the norm.



I have been using the Inon S2000 strobe with fibre optic sync cord but that presents some problems. Because the strobe always copies the camera strobe it always gives 2 flashes. That means you cant use full or half power because the strobe can't recharge in time for the second flash.

Using the Triggerfish slave sensor with a wire sync cord and Inon Z220 means I can use the full range of flash power and have total control. The triggerfish can be programmed to fire on the first or second flash. The Inon's dials are much easier to read and operate too.

I also added a focus torch mount using Locline which matches the one on my SLR housing.

DIY macro lens mount and strobe arm

Just for fun I thought I'd make a macro lens mount for my Lumix LX3 in Coolpix housing rig.

Here's what I came up with to hold the Inon UCL-165 M67 onto the dome port.

The 90x75 PVC pipe connector was close to a perfect fit. I stuck some neoprene tabs in the 90mm end to make it a tight fit over the dome port.

I slipped a ring of PVC in the 75mm end to stop the lens pushing all the way through and bolted on small brackets to hold it in place.

For higher magnification it would be better to use a flat port but this macro lens mount means I can do macro and wide on the same dive. A stronger or stacked macro lens would be better because the closest focus on long zoom only came down to 20cm.

I also wanted to reduce the overall size of the setup so replaced the double Ikelite handles with this simple aluminium tray/arm made from 50mm aluminium flat.

Merimbula Divers Lodge - Eden Tugs

After Jervis Bay we headed down to Merimbula (4hrs) to stay at the Diver's Lodge and dive the Eden Tugs. The Tasman Hauler and Henry Bolte tugs were sunk as artificial reefs back in the mid 1980's in 25 to 30m. The Tasman Hauler is intact while the Henry Bolte has collapsed but boasts more fish life. They're only a 5min boat ride from Eden wharf and about 150m apart.

The diver's lodge has 3 large two bedroom apartments for $29/person, 4 bunks per room. Absolute luxury as dive lodges go, and walking distance to great restaurants and the main shopping drag. We've stayed there twice and always had an apartment to ourselves. Excellent washing and gear storage facilities are provided.

Dive time was 8.30 at the Eden wharf, 20min drive, where we geared up with a Pro Dive mob from Sydney. They were also staying at the diver's lodge and doing a wreck course. The dive boat is a Niiad RIB with just enough space for 12 divers and 2 crew. It's a fast narrow boat that has no storage space for cameras, have to be very vigilant to protect cameras in the pre dive melee.

The vis was 15 to 20m allowing for great wide angle shots. A big school of 60cm kingfish provided thrills on the Henry Bolte. Much better than the 5m green snot we had last visit.

First dive was on the Tasman Hauler then back to Eden for the surface interval, then back out to the Henry Bolte.

$120 for the double dive with your own gear.

For this trip I really wanted to concentrate on wide angle and video. I used my Nikon D80 in Ikelite with 2 Inon Z220 strobes all on manual and Sigma 15mm fisheye, and Virg's Panasonic Lumix LX3 in my old Coolpix 5000 Ikelite housing with a UK Light Cannon HID torch for video.

I took Virg's Macbook and edited video as the trip progressed. This gave me something to do during down time and show off to the non photographers each night.

Rich and I used drysuits, highly recommended, and although the water temp was 20c in JB and 18c on the Tugs, it made the between dive times warm and comfortable. Wetsuit divers shivered.

Next time I'll take my ali backplate rather than heavier SS just for easier handling out of the water, and use an occy neck sling or velcro retainer rather than the useless mouthpece plug.

Panasonic Lumix LX3 underwater

I have an old Ikelite Coolpix 5000 housing (circa 2003) which doesn't get much use these days, so I thought I'd try to fit my wife's wonderful Panasonic Lumix LX3.

It's a great still camera but also does 16:9 HD video and has a really nice 24mm wide lens.

With a minimal amount of tweaking, the camera now fits and I can start and stop the recording.
I tried the flat port first but that gave too much fringing and pincusion distortion so changed to the dome port with excellent results.

After 2 dives, one video and one stills, I'm thinking this is a brilliant compact underwater.
With this bodged together housing setup I don't have any controls other than shutter release (and manual flash output on my Inon Z220 optically triggered) so I used Aperture priority (f/8) with -2/3 EV (to reduce ambient exposure) and Forced Flash (which limits shutter speed to no longer than 1/30th)

Results are sharp all the way out to the corners thanks to the dome port.

Getting the camera into the correct position involved moving the tripod mount hole (and the base plate) to the left and further forward. The the camera had to be as far forward as possible without clashing with the long shaft of the knob on the left of the housing and the lens had to be concentric with the dome port.
This took a little bit of gouging and fiddling of the hole. Once I got the position right I flipped the base plate over and drilled one accurate hole.
Then added some thin plastic strips and tape to to the base plate lift the camera up a little.
I then carved a shutter release knob extension from an old nylon chopping board.
