But that makes it
12.6 to 13.25 Wide
7.2 to 8 Tall
5.3 to 6.5 Deep
So, Yes the Sea and Sea is smaller in volume by about 40% and lighter by more than 30%. (housing only, no ports)
I think your math is a bit (or way) off. The dimensions you are using include the width of the handles. It is impossible to determine volume of either as they are not square boxes, and handles do not equal internal volume. The Ikelite would have to be close to twice the size to have 50% more volume, so 40% more volume is not accurate.
Comparing the weight the Ikelite weight includes the tray, and handles, the Sea&Sea listed weight is the housing only, no handles or trays. Again the comparison is not accurate, and certainly not in the 30% range.
Reef photo sells the Ikelite housing for $1250, and the Sea and Sea for $1700.
The Sea and Sea will support iTTL with the Heinrichs adapter, but that will add $300 to the cost of the kit.
I agree that Alum housing are a bit sleeker, and look cooler. Looking cooler is not important, and I can find no evidence that the alum housings are any less flood proof vs. Ike's. Get Insurance!
Watching the reaction by some divers when a photographer brings on board a DSLR and strobe combination... well lets just say they are not thinking cool. They wondering where is my PnS going to fit in the rinse bucket, or thinking look at that monster, how obnoxious! :lol:
If you want to see a comparison on Ike vs. Alum housing size go
http://www.ikelite.com/web_two/2d200nikon.html
and at the bottom there is a compare size window that will bring up a pop up comparing two D70 housings.
I think a lot of people find all sorts of reasons to justify their decisions. I would love a sexy expensive housing, but objectively reviewing a lot of data on all these housing Ike wins hands down IMO for four reasons, price, iTTL built in functionality that works, service, price.
If I could find data that proved that alum housings were less prone to flooding, I'd consider spending the extra bucks. However what seems to be true is that flooding is generally user error, and taking good care of the orings and inspecting all seals seems to be what will help prevent a flood vs. who manufactured the housing.
