Marine life of the Southern Atolls in Maldives.
Shot on Canon 70D in Nauticam housing.
Lens using Canon 10-22mm, Sigma 8-16mm behind 9' dome.
Most of time I was using continuous AF and it's works well. The 70D is probably the first Canon DSLR with a usable continuous aufo focus system on video mode, it's smooth and doesn't jerk or hunt.
Shot 1080P, All-I, Standard profile (1,-3,-2,0). No color grading or sharpening in post.
Do you think it would be possible to buy 2 x Focus, dislocate the joints, and make a double-length legs? (I did this with my SLR-Zoom)
Would the Focus be rigid enough for that, or better go with something like Xit 404 or DIY legs using strobe arms?
I didn't try that but might be possible but I think you need something like "Loc-Line Assembly tool". Anyway for video rig, I recommend Xit 404 twist clamp leg, ultralight tripod leg or strobe arm (if you don't need extendable).
I don't know about marine grade, but the Gorillapod Focus has "machined aluminium sockets" in its legs. And it costs twice as much as the all-plastic Gorillapod SLR-Zoom.
(Just to recap, I bought a load of Gorillapod SLR-Zoom a few years ago and modified it to use as light arms as well as tripod legs. They have all gone floppy and now more joints are superglued up than aren't. It sounds like others haven't had the same problem.)
I use both (SLR-Zoom x 2, Focus x 3ea) and same problem with SLR-Zoom but Focus still doing fine. btw, Focus is negative and SLR-Zoom is slightly positive.
