SPL Water housing for a Canon 7D 
W /go pro mount & 70-200mm port + a port that can fit fixed lens up to a 50mm , but not fisheyes - those are custom fittings.

I personally use my 35mm & 50mm in it. 

I have all the screws and accessories etc that are not shown in the pics but can sent if needed . Please inquire if any questions

I originally paid $2600+ for this setup (still have the invoices) 


SPL Water housing for Canon 7D w/50mm port $1,888 

                             +Port for Canon 70-200mm $603

                                              +GoPro Mount $145

                           Total Spent on the set up= $2,636 

    

and the thing with water housings being custom fits, they don't decrease in retail prices or devalue. It would still cost that same price today if you went through SPL aka Sean Lebrie in San Diego.
