Canon 1D Mk IV confirmed to work in 1D Mk III underwater housings
Great news for Canon 1D / 1Ds Mark III shooters! At the DEMA Show 2009, we confirmed that the upcoming Canon 1D Mark IV works perfectly in underwater housings designed for the Canon 1D / 1Ds Mark III.
The only possible issue is that by default, the 1D4 uses the FEL button to start and stop video. Some housings, like the Seacam housing we used for the test, do not provide for access to the FEL button. It looks like it will be easy to modify the ISO lever so that it hits the FEL button instead, but then photographers will have to find another way to change ISO. Hopefully, the 1D4 will feature a way to change the video start/stop button so hardware modifications are unnecessary.
