Canon’s new flagship camera the Canon 1D Mark IV is a perfect fit for Aquatica’s current housing for the Canon 1DS Mark III. If you already own this housing and want to upgrade to a 1D Mark IV, no modifications are required and no function or access buttons are sacrificed when using the newer Canon body. Of particular note, access to the video mode requires no modification.
Access to the FEL button used to activate video capture was already in place as well as other important buttons such as exposure compensation, ISO and the illuminator button. Reassignment of these functions through the DSLR’s custom menu setting is not necessary. Visit the Aquatica website for more information.
