Thanks for the great info!
What do you think about the Canon XTI? I've used, and owned, Nikon's before but never a Canon. I know what Nikon offer sin glass, but have no idea what's out there for canon.
I see that B+H has some basic setups that could get me started and then i could add lenses and ports on later .
Here's there 40X with a Fantesea housing:
Fantasea Line | FD-40X Housing w/ D40X / 18-55mm | B&H Photo
This is the Canon/ Ikelite version:
Ikelite | F-400D Housing w/ Canon EOS Digital Rebel XTI/ 18-55mm
I've used, and know many others who have owned, Ikelite systems in the past. They are bulky, but cheaper than other brands. They don't hold up to technical diving depths, but would be fine for freediving. I have NO idea about fantasea. Are they any good? Will they hold up? I see that they have flood insurance, but does that mean they had problems in the past, or are they just so sure of their product they throw it in for free for the first year?
