Upgrading underwater kit

[DivingKDawg]

I've had a Canon G7X with Ikelite housing and 2 x DS51 strobes for years and happy with the results vs size but I'm ready to upgrade to a larger camera for more control/less soft buttons to scroll through. I'm looking at a variety of Canon and Nikon DSLRs both new and used. Hoping to keep pricing for a full package (camera/lens/housing/strobes) under $5K (may have some wiggle room if the right package comes along). What Canon models should I be looking at and what lenses work best in an underwater housing (Likely Ikelite although Sea and Sea is an option. Nauticam seems to be a much pricier option.) I also own an old 7D but I want a full sensor and prefer the look of Canon 5D images over the 7D. Thoughts? Thanks in advance.

For Canon mirrorless full frame the most interesting to me is the RP (small and not expensive) but the only hopusings are SeaFrogs and Ikelite. Going to the R5, your budget is used up pretty quickly. I might look at Sony, a7c is like $1600 and housings are available (but Nauticam is more than $3K. If IKE works for you then I really like the RP.
