40D housing, ports, strobes, everything! HELP again!

If you aren't committed to shooting wide angle, skip it completely for now. Stick with the 17-70 sigma for your recon dives in a new location or when you can't make a decision.

At least that's what I'd do.

Does everyone agree that I am missing a beat with the 17 - 85mm lens? Realistically what will its performance be like underwater? The sigma lens mentioned sounds interesting. Has anyone else used it?

Thanks

I should add I do prefer macro - however my previous set up was a point and shoot and simply didn't perform at all for general reef shots etc so I will enjoy being able to get a decent shot of a shark etc.

I don't think the 17-85 offers the macro capabilities like the Sigma 17-70 does? Whatever you decide make sure there is a port to fit your chosen lens.

The Sigma 17-70 is a very popular underwater lens so a little searching will hopefully find more examples, if that's what you're looking for.

I have both the Canon 17-85 and Sigma 17-70. Maximum magnification ofthe 17-85 is 1:5 and 1:2.3 is the maximum for the 17-70. Therefore the Sigma 17-70 has more than twice the magnification of the Canon 17-85. A lot of reviews rate the Sigma 17-70 better than the Canon 17-85 optically as well. Guess which one of my two lenses get used all the time and which one sits on the shelf?
