Introduction

The lens unit is usually damaged when the camera is dropped on the ground or experiences some other kind of impact. If the lens unit does not move when you turn the camera on, it will need to be replaced. If the lens is cracked, it will need to be replaced. All you need for this guide is a Phillips 00 screwdriver, a Phillips 000 screwdriver, and your new lens unit from Fujifilm. As long as the camera is turned off and the battery is removed, there are no safety risks involved. To protect your new lens, always put on the strap when using the camera, and keep it in a case when you are not using it.

Step 1

The battery compartment can be found on the backside of the camera. Pinpoint this compartment and focus on the right edge of the compartment gate to find the opening latch.

Step 2

Pinch the latch in towards the battery compartment gate. This will release the gate and allow it to open.
Completely open the gate and remove from camera. Take out the battery and replace the gate.

Step 3

Face the front side of the camera towards you. To locate the left side turn the left side of the camera towards you.
Take out the four screws, sized 4.75 mm, with the Phillips #000 screwdriver.

Using a Philips PH0x60 screwdriver works well too

Step 4

Looking at the left side, flip the top of the camera towards you to locate the top side of the camera.
Take out the screw sized 9.75 mm, located on top side of the camera, with a Phillips #000 screwdriver.

Step 5

Looking at the top of the camera, flip the camera 180 degrees to locate the bottom side of the camera.
Take out the screw, sized 3.75 mm, located on the bottom side of the camera, this time with a Phillips #00 screwdriver.

Step 6

Remove the silver casing from the top of the camera. It is loosely clipped in and should come off easily.
Using a thin spudger, remove the chrome plastic cover from which the film is ejected. It is clipped onto the main body of the camera, and should come off with a sharp pull.
Using a thin spudger, pry off the silver casing from the bottom of the camera.
The bottom silver casing is clipped on tightly around the film ejection area, but is not held on by any screws or glue. Make sure to unclip it fully (this may take some force) before removing it, to avoid breaking it.

I had to pry off the silver casing firts, and then remove the anchors. There are screws holding the anchors under the silver casing

Step 7

There is a 4.75 mm screw located above the film ejection area. Use a Phillips #000 screwdriver to remove it.
Using a Philips #000 screwdriver, unscrew the strap anchors from the top and bottom of the camera.

Step 8

Open up the camera by releasing the latches on the top and bottom of the camera. There are 2 latches on top and 2 on the bottom. Once the two halves of the camera are unhooked, you can easily pry open the camera with your hands.
Set camera down on a flat surface with both sides facing up.
The top shutter button is connected using two thin soldered wires (black and red) to the main board. Use caution when prying the camera open.
Avoid touching the area around the flash capacitor (the big black cylinder) as it could result in an uncomfortable (but non-dangerous) electric shock, even with the battery removed.

Step 9

Set aside the black, plastic loop located inside the lens cavity.
Use a Phillips #000 screwdriver to remove the two 3.75 mm sized screws marked in the photo.
Move aside the motherboard located under the top screw. Then remove the marked 3.75 mm sized screw.

The third screw in this step is incorrectly marked. The one that has to come out is actually the one to the right of the one marked. The board is probably more precisely referred to as just a circuit board not a motherboard to be nitpicky.

Step 10

Remove the next two screws with a Phillips #000 screwdriver. The upper screw, sized 1.75 mm, is facing in towards the center of the lens unit. The lower screw, sized 4.75 mm, is to the right of the upper screw and faces down into the camera.
