The six inch dome port, product #5516.15 with zoom wheel works with 10-18 F/4, 16-36 F4, 16-50, 16-70, FE 28mm, FE 24-17mm and more. Each lens may require a different gear and some of the longer lenses require an extension. The port is $350.00 and the gears run around $24-$30.00. Almost every fixed lens and macro lens requires a different port. While I agree that U/W photography is not cheap, try finding many ports from other manufactures that are as inexpensive.
My preference for the 10mm end of that zoom would be the eight inch rather than the six inch port, but you should get decent results.
