PREPARATION OF THE LENS

Depending on the lens used, there are a number of gear options possible. Using the right gear (s) and correctly mounting them on the lens is very important for a smooth housing operation. Use the following chart to determine which gear(s) to use and follow the installation directions for each gear carefully. Since the aperture control is achieved through the Sub-Command Dial, the use of AF types of lenses is mandatory. The focus/zoom gear can vary from one lens to the other.

Refer to the lens selection chart on page 14 for compatible lens,

If the camera is set in manual focus a focus gear must be mounted on the lens. If you are using a zoom lens with a zoom ring the camera must be on auto focus, also note that if using an 8” dome port you may need to install a closeup diopter on the lens to correct the minimum focusing distance of the lens so that it will be able to focus on the virtual image created by the dome.

Focus Gear installation:

1.Set the lens to minimum focus distance.

2.Mount the focus gear over the focus ring of the lens such that the round indentation etched on the side of the gear is facing the rear of lens and is aligned with the Distance Index of the lens (for full gears orientation is immaterial).

3 (a) For Slip-on gears (gears without mounting screws): Slide the gear over the lens and align the gear with the front of the lens focusing ring.

(b)For gears with mounting screws:Tighten the three set screws evenly. Tighten each screw approximately ½ a turn working around the gear until all the three (3) screws are tightened, and the gear is concentric with the lens body.

CAUTION: Do not over-tighten these screws, as this might bind the lens barrel, thus restricting the rotation of the focus ring and/or damaging the lens. Conversely under-tightening these screws might cause the gear to slip or lose alignment.

4.Rotate the focus ring several times to make sure it moves smoothly and the gear does not slip before closing the housing

WARNING: Never attempt to operate the camera in autofocus mode with the lens mounted focus gear engaged. This might cause serious damage to your camera or to the lens.

Zoom lenses: When using a zoom lens, the focus/zoom gear should be mounted on the zoom lens control. The housing focus control becomes the zoom control. Focusing of lens is achieved by using the camera’s autofocus system.
