In Topic: Deep Wreck Project - lens-port combo?

06 March 2014 - 09:48 PM

Harry,

I've had the aquatica 6" dome to 140m, seemingly no ill effects.

The 6" dome gave me a good size compromise on crop sensor, though after moving to full frame I typically got blurred edges past f/8-10.

Given the dive at hand, is be happy to take that image qualify hit to reduce size of rig.

I never tried the 4" dome due to suggested quality issues with full frame.

Another side effect of the smaller domes was the weight of the housing rig. I found this quite a serious issue, and adding your lights to it will only compound this.


I'm now using the nauticam carbon fibre float arms, they're at least good to 125m based on my tests without compression. Two 12" unit provide some serious lift too, so should address the negativity.

I've had Inon z240s to 140m many times, no ill effects. Ikelite DS125/161s also seem to handle the depth ok, though I've only taken them to 120-130m.

More than survived, worked a charm. Actually have a SLR rig at depth that was positive and not mega negative was a pleasure.

I imagine with video lights on camera that the large carbon fibre buoyancy arms I used would trim the rig nicely instead of being too positive.

I just took a Nauticam 5d3 rig, with 8.5" acrylic dome and carbon fibre float arms to 125m. worked a charm, quite impressed with housing to be honest

was also testing a fisheye focus light to the same depth, no issues at all.

In Topic: Macro with Canon 5D3

I'll add that after a week or two shooting with the 5d3 macro and WA full time, it's a pleasure to use. AF when used correctly is awesome for macro and wa.

I had the orientation settings out of whack which gave me the issues. Also the tracking was not what I expected and led to confusion, but after using it on more than a static deep wreck I'm rather impressed.

Time to look at that sigma 150mm I think as well.
