Lens error


I've got the answers...

Problem: Lens error.
Symptom: Lens will not extend upon power up.
Cause: Lens is impeded while trying to extend.
This is usually caused by one of two circumstances. (1) The user dropped the camera while the lens was extended causing a mechanical failure. (2) The lens attempts to extend while in a pouch or pocket without the user's knowledge. This usually happens when the user is carrying the camera with the battery in. When/if the REC button or power button is pressed accidentally, the lens will attempt to extend but can't. This causes the main drive gears to be damaged.

Solution: Replace the main drive gear assembly. This should only be done by a qualified tech.
If you've experienced this you know exactly what I mean. This should clear up any notion that the "Lens Gods" have cursed you. Although this may have appeared to be a mystery, it's always caused by something!

Problem: Lens error.
Symptom: Lens extends, makes a few buzzing noises and retracts, resulting in "lens error" message.
Cause: This is caused by damage to the focus lens often by impact, or sand in the mechanism.
Solution:The focus lens gears either need to be replaced or the assembly completely rebuilt. Again, this should be done by a qualified tech. It's a very delicate process.

Problem: Aperture unit failure
Symptom: images appear to be washed out, over exposed and often have horizontal lines through them.
Cause:The aperture unit is either stuck, damaged or not receiving the proper electrical signal to activate. The result is that the aperture remains open after the picture is taken and CCD is over exposed.
Solution:Completely rebuild the aperture unit, which requires complete lens dis-assembly and rebuild. Again, this should be done by a qualified tech. It's a VERY delicate process.

Hope this helps.

Turns on for a few seconds, lens starts to extend, turns off.


Assuming that the battery is OK, the most likely cause for this behaviour is an out-of-kilter lens drive. If you are lucky it's just some dirt or grit jamming the lens. Try blowing some compressed air in the lens grooves, or place the camera with unextended lens down and gently tap it to dislodge any dust or sand. Repeat while lens is extending. If this fails, GENTLY try to help the lens extend. Do not force (you risk permanent damage to the lens, assuming there is no damage now). If the lens rotates while extending, still gently try to help it to rotate, twisting in the direction of rotation.

Unfortunately, it's possible that the lens drive is actually damaged and can't be realigned manually. In this case the camera will need to be repaired. Also, even if you succeed in refitting the lens - you'll hear a slight "click" and the lens will start working happily - you'll need to exercise extra care in case the drive is no longer up to spec.

Unfortunately, "extending lens" cameras are very sensitive to accidents such as turning on while something is blocking the lens from extending fully. In most cases there's an overload sensor which will retract the lens and power off the camera - but sometimes the overload will have damaged the internal drive train, which is often (not very cleverly, in my opinion) made of plastic instead of metal.

Canon PowerShot SX100 IS Lens Stuck


If the lens does not extend/retract when the camera is powered on, then lens assembly is damaged.

Unfortunately, such Canon SX100 (and the SX110 too) has a very fragile lens assembly, and it's damaged very easily. Most of the times the internal gears, the plastic post guides and the motor are damaged at the same time, so the only solution is to replace the whole lens assembly.

The lens replacement requires a qualified camera repair technician, unless you want to try in repair it yourself, which requires tools (scredrivers, soldering iron, desoldering tool, magnifier glass with light, etc).

Lens Problem


Hi Kento,

Thanks for accurate description, the problem is cristal clear.

As often happens the lens had been damaged by the shock.

All you can do is trying gently to push the lens inside with your finger while turning camera on and off.

This will probably not work, as lens gears are bent and damaged.

The whole lens barrel must be taken apart and remounted. Probably some part need replacement.

If it is still under guaranty it wont be easy get this kind of repair covered, only way to cover it is if the camera came like this in package, I don't think you can get away with it.

Casio EX-Z700 was dropped in sand. When camera is turned on lens makes a grating sound and the moniter screen is cloudy. It originally said lens error, but no longer says anything.


Hello, I'm Mark Faith from the states. I purchased the CASIO EX-Z700 series.
However, I accidentally dropped the camera when the camera was on and the lens was extended.
It makes a grating sound, and the monitor screen said "Lens error".

Now, the camera is turned off with its lens extended.
When I see the lens from the top, the lens position is more concentrated to the right, and the gaps between each lens is bigger on the left hand side of the lens.

I sincerely hope this would help you to analyze the lens situation.
I'll be patiently waiting for a list of solutions.
Thanks.

Mark

My Pentax Optio S7 has developped a fault. When I turn it on, the zoom pops out, the screen lights up but it makes a buzzing sound then the zoom retracts and it switches itself off.


The gearing for the lens has become damaged and the lens can no longer fully extend. As a result, the camera detects a fault when attempting to extend the lens and shuts itself off. The most frequent cause of this kind of damage is dropping the camera with the lens extended. Always used the wrist strap!

Unfortunately, there is no way to correct this at the consumer level for this camera. It is very compactly designed, and the lens is the hardest to get at. Even if you were able to get to it, you'd still need the replacement part for whatever has become damaged. You will need to return this for repairs - although with the price of this camera, buying a new one will probably be cheaper.

My SD110 problem sounds similar...any ideas?


It sounds like the gear train that extends/retracts the lens is not meshing properly. This can happen due to dirt/debris getting in around the lens units and into the gearing, or damage to the gears due to impact (dropping the camera with the lens extended). You might try blowing some "canned air" around the lens while turning the camera on/off to see if you can dislodge the debris, but the unit probably needs repair to get it functioning correctly again. That model is about 4 years old, and for the price it was selling for in 2004, you can get a really nice new digital camera at today's prices.

Lens error


This error... lens error.. can be the result of many abuses. If the lens is held back as it is extending, it can damage the tiny parts. If the lens is bumped while it is extended, it may damage the internal parts beyond repair. Sometimes the lens get off track as a result of a blow while extended.
If the camera is dropped, the lens mechanism can be damaged from the impact, even though it is not extended.
If you treat a digital camera with a lot of care, and put in a padded camera bag, you may extend the life of the camera.

Lens doesn't extend


its likely the lens was physically damaged/jammed during the drop. Your best bet is to take it to the local camera shop for repairs. I would also refrain from turning it on to reduce the possibility of further damage.
