Trying to piece it all together - 5Dmkiii, housing questions(s)

[goclimbing]

I've been shooting a 60d top-side and a s100 under. I've had my eye on the 5d mark iii for both purposes and am getting ready to take the plunge.

I opted against housing the 60d because I knew one day I'd add a mkiii to the quiver (will keep the 60d as a second body) and simply wanted to wait until I have the FF camera before outfitting a dslr for underwater. I've invested into the lenses knowing I'd eventually upgrade and wouldn't need new glass.

I'm looking at the Ikelite housing.

What I am trying to figure out is what view ports I should consider and then what lenses. I've done some digging on the net but it's about as clear as mud to figure out the right combo possibilities.

the sigma 2.8 15 is one option.

Tokina AT-X DX 10-17mm F3.5-4.5 Fisheye is another


thoughts or advice?

The Sigma 15mm is a great option if you're on a tighter budget.
A pricier but more common choice is the 16-35mm, which will give you some more versatility and better quality.
Using the 10-17 is optional and a fantastic lens, especially for that budget, but on full frame it will mostly be used at the 17mm end and it tends to be a bit soft at the widest aperture, so take that into consideration.

I posted a full dSLR lenses guide a while ago, you are welcome to use it and see some examples taken with different lenses: Choosing the best lens for DSLR underwater

For macro the Canon 100mm is the most popular lens among full frame shooters, since the 60mm produces a shorter working distance from your subject.

As for ports, each lens will have a combination that fits best. I would usually recommend the 5510.45 8" dome for wide angle.

I think Ran is right, the 16-35 is probably the best wide angle rectilinear lens. The Tokina is not quite so useful on FF (it can be used with a 1.4 tele quite nicely). You should look at the Canon 8-15 for some really cool photos. The 100 mm macro lens is probably your best bet.. Don't forget strobes, arms, focus lights etc.
