Canon 5d Mk2 to Mk3 to Mk4

Hello Canon experts.

The camera bodies look very much the same so would it be possible to use my Mk2 housing for a mk3 4 or 5 body?

I have no clue if the buttons dials and all are completely different positioned.

Thanks in advance, Fredrik.

I tried and the Ikelite is a no go. The mkiv is taller and iso button in a different location. What brand housing do you have? 

Thanks Chris, i got an aquatica 5d mk2 housing because i wanted the vaccuum kit and parts from it but guess i get it running with camera inside. Question is if any of the marks is same geometry and buttons and measurements like the mk2?

There is a kit for the Aquatica 5dmk3 housing and convert it so it's compatible with the 5dmk4, but you're out of luck with a 5dmk2 to 5dmk3.

The 5dmk3 and 5Ds/sr are identical bodies though, so I was able to use the 5Dsr in my 5Dmk3 housing...however, I left the Canon camp a while back and now use Sony.
