I've been meaning to share some shots from my 5D MKIII running ML RAW. Our viz has been really bad until recently and there are still a lot of particulates in the water. 

 

In any case, I wanted to illustrate what I consider to be an amazing benefit from this firmware aside from the increased detail and latitude. I have a 8-15mm f/4L fish-eye behind a Zen DP-100 mini-dome. It has a fantastic MFD. With the crop feature on the firmware, I can get a 3X zoom factor on the lens. At the push of a button, I now have a 24-45mm lens with no loss of quality. Here is a  A Pacific Spiny Lumpsucker (Eumicrotremus orbis) during my safety stop:

 

First shot is at 15mm, second shot is at 15mm x 3 = 45mm. 

 

 
 
With my 100mm macro, I can now get 300mm of focal length. If I attach my SubSee +10 diopter, it's a crazy amount of magnification. 
 
 
I pretty much have all of the workflow down and don't really have any issues getting consistent 1080p at 24fps from it. ML RAW for underwater video is an amazing tool. I can't get enough of the quality and latitude. And now I have a super wide angle/ portrait lens behind a mini-dome!

Nice video and rig.
The tripod leg is Ultralight?


Thank you! Your work is a huge inspiration.

Yes, these are ULCS tripod legs. I like them, though I have no point of comparison. I wonder about the XIT404 legs with the twist clamps, but I don't find myself have to tighten the leg clamps all that often. I'm also a little worried about the spikes puncturing my dry gloves or dry suit, even with the half-cut whiffle balls attached, so I keep a close eye on them when entering the water.

A photo or more would really help, can you?

Great behavior video!!

How did you manage to hold so still with the 100mm? I am amazed at how much you were able to get in focus. Hand holding marco is very difficult with the dslr. Any tips you wish to share?

Hard to describe without a photo of my setup. I have two 8 and two 5 ULCS arms with StiX floats on them. I also have the float belt around my macro port. I also have XIT404 tripod bracket and three tripod legs from ULCS. With the float belt and the floats on the arms, the rig is just slightly negatively buoyant. The float belt helps helps keep the awesome Aquatica macro port with a manual focus knob in a mostly neutral position. The focusing was also aided by using Magic Lantern firmware that gives me a "Focus peaking" feature, which I find to be incredibly helpful since I have yet to consider buying an external monitor. The size of the rig helps too since it actually takes some effort to push around in the water column. Hope this helps.

Great capture! You know you have to go back and get them hatching right?

Thanks for sharing it,
Steve


Thanks! And yes, absolutely. The cool thing is that I should hopefully be able to time the cluster they layed that night. They take 4 weeks in 60F water. Our water is a bit cooler at 45F, but I'll at least have two chances, with the original cluster I've been watching develop eyes and this new one.
