Sand in focus/zoom ring

Hi

There is a couple of sand particles in the zoom/focus ring of my camera and i just want to remove the ring to blow away the sand. It makes a grating noise when i use the ring.

Now I just want to know how to disassemble the ring, preferably not the whole lens assembly. I don't want to mess with the optics!

Any help appreciated.

How do I get the lens barrel to slide smoothly?


The lens you seem to be referring to is the14-42mm.these were the basic consumer kit lens and has a tendency to allow dust and debris to enter via the rear element/ mount.this is relatively easy to access and fix.you need to have a small Philips screwdriver some QTips and a fine paintbrush or blower.whilst the lens is facing down on flat surface...remove the four screws that hold the mount to the lens body.remove the electrical contact strip screws...you have to be careful and slot the electric contact through past rear mount whilst gently lift up the mount so as not to break the ribbon cable.you should see a small metal cog on pin .check slot position when zoom is closed..then this can be removed and inspected for sand and dust particles.brush anything off the cogs.inspect the internal cog ring whilst turn zoom slowly for any debris.clean and remove any particles.reinsert cog after you zoom closed and return cog to correct position.check if the zoom is now smoother.feed electrical contact back through rear mount re screw.always keep rear cap on lens when not in use.never travel to beach environments as you will most certainly introduce sand into the mechanism.if the lens is still jumpy then it is likely debris has entered within the deeper mechanics of the zoom mechanism.this is much more fiddly to do ...I think YouTube has some strip down tutorials on similar lens.good luck!

My camera getting hang


The non-functioning of the camera can be a fault in the shutter, zoom or auto focus sections and may be due to the failure of the Main control system or the drive. A simple was is to reset and we can try by removing the battery and card for some time. Now replace only the battery and while switching power ON, tap the lens hood on the palm of your hands so as to disengage any dirt or mechanism being struck.
If you had happened to visit outdoor specially the beach then it is possible that fine particles or sand can be trapped within.Use some air to blow between the lens to dislodge any sand particles struck inside. Unless you are familiar with handling of small devices must the camera be opened. If so check the voltage on the motor drive, check the auto focus and Zoom drives, it must be free with manual movement. If jammed the motor can be removed and released. If none of these works then you can think of taking consensus with the service centre.
Get estimate before you decide. It will be good to have it checked at the authorised service as you do not have to run around for spares.

Lens will not extend when turned on message on screen lens error


Hi,

This error indicate that focusing ring got stuck or jammed due sand, dust or may be due to external shock caused by dropping the device.
  • Try compressed air. With a fine tip blow off gun around lens barrel. It should remove all dust and sand. Turn the camera on this will solve the problem.
  • You can gently bump the camera to try to free the focusing ring.
  • You can try to turn camera ON at the table (facing it to the ceiling), don't put camera down face to the floor when opening.

If motor is running but lens won't retract sometimes lens would slip off with the gear or break off a tooth in the gear when it gets dropped. Try to gently move the lens barrel around with the finger and see if it is moving, but if tooth or gear is broken lens will move once or twice then it will stuck again.

Else your camera need to be disassembled to get at the focusing ring at Service Center.

Thanks and have a nice day

Machine clicks when turned on and focus is stuck. it sounds like focus gears aren't meshing properly


hi, Zoom/Focus Error occurs when there the lenses are not able to move and something is obstructing the movement like some dust or sand grains etc., to dislodge the obstructing particles try tapping the lense side corner of the camera on a table top lightly (not too hard please, as the lense and autofocus combination is quite fragile) a couple of times in switch off mode and trying to power on after every 2-3 taps.

hope this helps
cheers

My daughter dropped her sister's Nikon Coolpix S560 in the sanddunes today with the lens open. It still took pictures after that but the lens wouldn't close. Now it opens and closes and makes a grating...


It seems that some sand particles are lodged between the lens casing and the camera's body. and when it finds that there is resistence in moving the lens, it shuts down. Use somethig that sucks, like the vacuum cleaner to **** the sand particles out. Do not blow, else the sand will go further in.

Lens error please help!!!


If the sand is in the zoom gears or auto focus gears then the camera would need to be disassembled to remove. Nice thing about this camera is that no soldering is required to take apart. A few small screwdrivers, and some tweezers would be all that is required. Canned air and a needle might also be helpful for removing the sand. If the camera just buzzes then I would say that the sand is in the auto focus gears (the stepper motor will buzz). If the auto focus lens is not fully retracted then the camera lens will not go back in (to prevent the auto focus lens from bumping against the shutter assembly)

Whenever i on (start) camera ,Zoom Nikkor is not opening


Hi,

Your guess maybe right.

If your camera is of SLR type then you can easily open the lens and give it a vaccum blower to blow dust.
If it doesn't work or your camera is compact type then you have to seek help of good mechanic.

Hello sticky, This is a lens assembly mechanism problem. It is a delicate part of any camera. Altrought some people may sugest you to use a compressed air spray to remove the sand in the inner lens by blowing it out i don't recomand that because sand particles can be pushed out even further in the lens and could be causing even more damage. The lens assembly is composed of several servomotors, coils, some sensors and the actual lens. It does the following jobs: it extends the lens back and forth achieves focus by moving the lens zooms the lens by rotating them in the same time as the whole objective is moved back and forth Each of these operations is controlled by some servomotors who actually move these parts and are also connected to some sensors that pass the readings back to a main processing unit. When you open the camera this processing unit will check to see if the lens assembly is able to do all of these 3 things. Failure to comply with even one of them will result in some error (lens error) or simply having the camera not opening. "Lens error" or "zoom error" is a generic message, doesn't mean that the lens itself are damaged, could be the connector to their servomotors, sensor failure, some coils that are out of position and things like that. In your case the sand particles are preventing the servomotors to properly align the lens. They are all related to the lens assembly. Because this is a VERY fragile part of any camera I don't suggest you to try a DiY repair because you can damage the lens even further. Even service centers have problems repairing this, most time it is done under a microscope and some times it simply can't be fixed. This problems occur most of the time in corelation with the camera being dropped or received some shocks but even some small particles or sand in your case, can cause this problems as you can see. I would recomand you to go to a service center. Try not the big ones that represent large corporations (because they are expensive), instead look for a smaller one. Tell them you have a lens assembly problem, also tell them that it's caused by sand, ask them to make you a diagnostic and then ask for a cost estimate BEFORE they actually repair the camera. If the lens assembly is damaged beyound repair it will need to be changed as a whole, including all connectors, CCD sensor and so on. This could cost from $70 - $200 excluding labor parts that can be about $100. Therefore you should ask them a cost estimate. I'm sorry for not being able to provide a DiY solution but like i've said, i don't recomand one. In the future try not to expose the camera to any shock, sand or excesive dust and temperature variation. These are all known to give a great deal of trouble with digital cameras. If you need more info please post back. Good luck.
