Please take note of these points of advice: - O-rings should be absolutely clean and be greased thinly. We recommend the use of waterproof Silicone grease (eg. SUBAL-Silicone grease). Too much grease results in the accumulation of small dirt particles which are invisible.
It is absolutely essential to change them regularly. Please note that the especially soft quality of the original SUBAL O-ring material looses elasticity prematurely if it is permanently compressed. So, if you plan not to use your housing for a long time,...
PREPARING THE CAMERA There is nothing to change on your Canon 7D for the use with SUBAL CD7. Knowledge and familiarisation with the functions of your camera is essential to avoid mistakes when installing and using the camera. We recommend you study your camera manual thoroughly before installing the camera.
PREPARING THE LENS To change the focal length on zoom lenses, or for manual focusing with fixed focal length lenses, special lens gears are required which need to be fitted to the lens barrels. Mounting the gear rings Zooming gear ring Depending on the type of the lens, the zooming gear ring is fitted onto the lens either from the front or from the rear.
When rinsing the housing make sure the port is attached properly and flash sockets are sealed with plugs if no strobes are fitted. The SUBAL Quicklock System locking levers are spring-loaded and require that they be depressed before rotating. Warning! Do not forcefully turn the levers otherwise damage could occur.
Check the proper function of the ON-OFF control before closing the housing. CHANGING A LENS SUBAL CD7 allows changing the lens without camera removal. Remove the frontport. Turn the lens release knob clockwise approx. one quarter turn to release the lens lock mechanism.
THE INTERCHANGEABLE PORT SYSTEM For your SUBAL housing, there is a wide range of front ports available, the largest of all manufacturers. This allows you the use of a multitude of regular lenses under water, ranging from fisheye lenses, extreme wide angle-lenses, zooming lenses and macro lenses.
OPERATING THE FUNCTIONS The operation of the camera functions is the same as surface use: By pressing the corresponding levers, push buttons or turning of the knobs. If illumination of the subject is insufficient to guarantee proper autofocus operation, additional lighting has to be used (pilot light of flash unit, etc.) or the camera has to be switched over to manual focus.
MOUNTING AND CONNECTING A FLASH UNIT A wide range of perfected strobearms are available for the combination of a SUBAL CD7 housing with SUBAL flash housings and strobes of many manufacturers. The arms are fastened by pushing them onto an adapter plate on the upper part of the housing. The swivel arm is secured by screwing the footscrew into the center indentation of the adapter plate.

CHECK-LIST After ensuring that the main O-ring has been installed and the housing closed properly, please check carefully ONCE AGAIN, whether: The gap between the housing frontpart and the lid seems equally spaced all around. The gap between the housing frontpart and the frontport seems equally spaced all around and the O-ring has not been squeezed out.
