Inleiding

Here we´re dismantling a digital camera in order to clean a stuck/obstucted lens mechanic.

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.

    • 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.

    • To release the LCD ribbon cable lift the tiny black bar carefully with a fla blade screwdriver or spudger

    • Second pic shows open connector

    • Front shot of the camera

    • 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.

    • The metal frame separates from the rest of the camera.

    • It´s still connected to the black plastic of the bottom part.

    • Rotate it counterclockwise to unhook it from the little plastic pins

    • Finally the metal frame is gone

    • As before, carefully lift the two black flaps of the camera sensor and lens connectors

    • Second picture shows flap up

    • The lens body (and sensor) are removed

    • Remove four phillips screws, one is hidden under a small cover

    • Unhook one clip

    • Place the lens facing down before continuing.

    • Carefully pry the box open as shown. The top part is the sensor, so once open do try to keep it clean.

  12. Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (1): stap 12, afbeelding 1 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (1): stap 12, afbeelding 2 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (1): stap 12, afbeelding 3 van 3
    • First a picture of the sensor and the rest

    • Now remove two small gears as shown

    • 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

  14. Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (3): stap 14, afbeelding 1 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (3): stap 14, afbeelding 2 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (3): stap 14, afbeelding 3 van 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

  15. Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (4): stap 15, afbeelding 1 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (4): stap 15, afbeelding 2 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (4): stap 15, afbeelding 3 van 3
    • 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

  16. Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (5): stap 16, afbeelding 1 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (5): stap 16, afbeelding 2 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (5): stap 16, afbeelding 3 van 3
    • 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

  17. Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (6): stap 17, afbeelding 1 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (6): stap 17, afbeelding 2 van 3 Repairing Casio Exilim EX-Z350 Lens mechanics, Disassemble lens (6): stap 17, afbeelding 3 van 3
    • 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.

  18. Repairing Casio Exilim EX-Z350 Lens mechanics, Done: stap 18, afbeelding 1 van 1
    • 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.
