Introduction

Camera fails with “lens error” while switching on.

Happens because the camera is not rugged and dirt can penetrate the lens from the front.

Guide describes taking the camera apart including the complete lens. During all steps careful cleaning / removing of dirt is not speciffically mentioned in the steps.

What you need

Step 1

              Opening camera case

Camera flash circuitry contains a high-voltage capacitor. This is charged after turning the camera off and removing the battery. Be sure you either discharge the capacitor or at least do not touch it in any way.

Step 5

              Remove camera from front housing

Insert spudger as shown to lift camera out of case on bottom area around the tripod thread first
Once the bottom part is out, its easy to carefully pull out the camera

Step 8

              Remove metal frame bracket (1)

Remove the two screws shown in first picture
Unhook the first easy to access clip on the side of the lens body
Unhook the second more obstructed hook. Be careful not to touch the capacitor’s connectors (black round thingy), it might still be charged.
If the two hooks are unhooked, the lens body can be lifted upwards.

Step 13

              Disassemble lens (2)

Remove small axis with a pair of good pliers. The axis needs to be removed as otherwise the zoom lens will not come off easily
Last picture shows the assembly with zoom lens still on.
When lifting the zoom lens, the stabilizer lens will swing up. Remember this upon assembly, as you will have to move it back (down) again

Step 14

              Disassemble lens (3)

Here´s the stabilizer lens visible
Lift the zoom lens as shown
The small gear has a notch in the housing that the nose must be fitted back in upon assembly

Step 15

              Disassemble lens (4)

The stabilizer lens (or what I call it, it might be the focus after all) is kept in place with three clips.
Red arrow shows direction in which stabilizer lens must be moved upon assembly
Unhook all three and the little noses come out of their holder
Carefully pull out the inner lens body.
Do not pull as it is connected with a tiny ribbon wire

Step 16

              Disassemble lens (5)

Lift the lens barrel out by pushing slightly from the front
Unhook the inner control ring as shown. The spudger needs almost no force and the ring springs out
The inner ring can be lifted out. It has three guides with different shape, so fitting back in is possible without a marking

Step 17

              Disassemble lens (6)

Now the last two parts can be separated.
Rotate the parts carefully against each other until the three metal noses move out of their guidance rails.

Step 18

              Done

Here´s a overview of all the parts we´ve got.
I really cannot work out how to correctly operate the crop tool…
Putting back together isn´t much more difficult, and would have worked in my case if not for the charged capacitor and a non-isolated screwdriver, but that´s a different story.
