Hello everyone!
I've recently started diving seriously (PDT), and want to start looking at underwater photo gear. I've made a pretty serious hobby of photography above water, my current gear is as follows:
Canon 40D and 350D,
Canon 10-22mm,
Sigma 150mm macro,
as well as a handful of other lenses less suited to UW, and a Canon 430EX flash.
Budget will be a concern, to be sure, which has me thinking I'll be going with Ikelite. Budget is enough of an issue that I'm almost wondering if I could save some money by getting a housing for a 350D rather than a 40D, but the 40D has so many advantages this would be a last resort kind of thing. I think my first priority will be macro photography with the sigma, but I'm equally in love with the 10-22mm, so a dome port seems pretty inevitable. I think I understand enough of Ikelite's port system that both my main lenses will work, but confirmation would be very helpful!
I'm a little uncertain about whether I should budget for a diopter for the 10-22mm, Ikelite makes mention of it helping corner sharpness. I understand this is about having to focus on a 'virtual image' effectively 3 ft from the lens due to the dome port, but would like to hear opinions about how big a factor this is on this particular lens, especially since I expect to be somewhat stopped down anyways.
I also know that I'll need a strobe or two, I've been hoping for a DS160 (or used 125), but budget may force me to look more closely at the DS51, and add a more powerful flash down the road. Would this be wise? Would a DS51 give me enough practical power for a stopped down macro lens? How about dealing with a wide angle of view?
Thanks in advance!!
