I've been asked about the SeaTool DSLR housing a lot recently since I wrote the "I Was An Idiot" thread, and thought a good follow-up would be to post some pics showing the Ikelite compact camera housing (in this case, for the Fuji F810, but they're using basically the same casing for most of their compact housings) and the SeaTool XTi/400D housing.
SeaTool is a newer housing company which started by making really tiny housings for video cameras, and are just getting into DSLR housings. The XTi was their first, they now have the Nikon D200 out, and they're in development for the Canon 40D.
Let's start with the front view of both housings, the Ikelite housing for the F810 and the SeaTool housing for the Canon 400D/XTi. Since they can both fit on the same tray, the accessories (strobe(s), arms, etc.), will be identical - so I just photographed the housings themselves. The size of the rest of the rig will be up to you - one arm or two, how long, what strobe(s), and so forth.
I have the 60mm macro port on the SeaTool housing, and to make it fair, two Inon UCL-165AD macro lenses on the F810 housing (since that's what I shot with when I was shooting macro before moving to the SeaTool). The two housings are set up for similar shooting conditions with these ports/lenses atached.
As you can see, they are pretty much identical in width and height. (If you're wondering, the blue in the Ikelite housing is painter's tape - my flash block broke a bit ago and this helped keep down the backscatter from the onboard flash, leaving a gap just large enough to trigger my Inon fiberoptic cords - the reason I used this tape is it's easily removable at a later point.)
Now a view slightly above so you can see the depth. The SeaTool housing is slightly deeper, but not by a great amount - most of it is the window for the viewfinder, which I have a "pickup viewfinder" addition, making it a bit deeper
Next the view from the top looking down on both:
I thought it would also be helpful for you to see them stacked in front of one another to see the width is almost identical - in fact, the F810 housing is slightly wider. In this pic, you can just barely see the top of the flash portion of the SeaTool housing behind the F810. The rear knob looking higher than the SeaTool is, however, a bit of an illusion - the sofa and book were not perfectly level. They're on the same plane:
Finally, to give you overall perspective on size, both housings with "medium sized house cat" next to them
As you can see overall, the two housings are almost identically sized, with the SeaTool being very slightly deeper, but height and width are in line with one another. This is remarkable considering the size difference between the F810 camera and the Canon XTi. That's the amazing part of the SeaTool housings.
So for those considering moving to DSLR, size of the housing itself doesn't need to be a barrier any more.
And no, I have absolutely no financial interest in SeaTool or either of their two US distributors (Reef Photo or Backscatter), nor am profiting in any way here. I'm just in a unique position to be able to provide this info to others looking to make the switch.
Hope that helps! Let me know if you have questions.
