Manual Lens Focus Wheel

The Survey3 PRO housing is compatible with our Manual Lens Focus Wheel. Once the focus wheel is installed you can rotate the wheel to adjust the lens focus.
To turn the Manual Lens Focus Wheel you need to remove the Lens Cover. Grab the Lens Cover and twist it counterclockwise. When the tabs of the cap are out from under the housing tabs pull the cap off:
If it is difficult to twist the Lens Cap you can use some pliers to grab it more securely. We apply some grease to the inside to help it twist, but over time the grease may thin and need to be replaced. We use Super Lube Multi-Purpose Synthetic Grease, but other similar grease can be used.
Touch the Manual Lens Focus Wheel and rotate it, which will rotate the lens and change the focus. It is best to watch the live video preview on the camera's rear LCD touchscreen so you can watch the focus change as you turn the wheel. The center of the image will focus first, followed by the edges.
Once the image is focused how you prefer, reinstall the Lens Cap. Push the cap fully onto the housing and then rotate it clockwise until it stops under the housing tabs. You want to install the cap with the tabs close to going under the housing tabs so that it is not rotating more than is needed.
Your manually focused Survey3 PRO camera is ready to use.
Follow our instructions carefully and you will not damage your camera and lens. MAPIR is not liable if you damage something while installing the Manual Lens Focus Wheel.
Remove the Survey3 PRO Camera Pull Tab if it is installed:
Use a plastic pry tool to pop off the green faceplate, working your way around to fully remove it. You can also use a thin card like an old credit card. There are small tabs holding it to the camera housing. Some tabs may break a little, but there should be enough to reinstall it securely later.
Set the green faceplate aside for now:
Grab the lens and unscrew it counterclockwise to remove it:
Locate the manual focus wheel which is compatible with your camera lens. The wheel with the larger hole in the middle (shown below) is for the wider angle lens of the Survey3W camera. The smaller hole wheel is for the narrower lens of the Survey3N camera.
Grab the lens and push it down into the focus wheel. Be careful NOT to push down on the colored filter which is installed on the bottom of the lens. If you crack the filter on the lens you will likely need to replace the lens.
The lens should be pushed all the way into the wheel:
Look at the lens from the front and make sure there is no gap between the lens and the wheel:
Unscrew the two small screws on the green faceplate:
Remove the black plastic lens surround:
Reinstall the green faceplate by pushing it onto the camera housing:
Screw the lens with manual focusing wheel clockwise into the camera lens mount. Go slow until you feel it thread in without resistance. The lens and lens mount have metal threads so it's difficult to damage the threads unless you do not install the lens straight. Sometimes turning it clockwise and counterclockwise until it grabs the correct lens mount threads helps.
Reinstall the Camera Pull Tab. Your installation is complete on the Survey3 camera.
Remove the PRO lens surround spacer if currently installed by rotating it counterclockwise and pulling it out:
