Lens canon 28-135 IS

Just one page of a repair manual from Canon. Just to ask yourself if you understand how to adjust a lens. If you can't make up anything from this, it is not worth buying a repair manual for this lens, because bringing it to a certified Canon repair shop will be cheaper. And the result 1000 times better.
Opening a lens is no problem. Putting it together so you can use it as sharp as it should be, needs special tools and special skills.

sounds like the motor is cactus to me, have you checked to see if there is any drive (power) to the motor?

If only the shutter eye is not opening but the lens is extending properly, then you will need to remove the fron shutter frame and review it.

It may be that one (or both) springs that open the lens protector are loose, or the plastic tab that allows to open/close the lens protector is broken.

If the lens does not extend 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 solutio 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).

Best regards,

Put in real Kodak batteries. pull out the lens a bit. same just happened to mine

Hi

What you are seeing is a generic error message, starting your camera again won't do anything unfortunately.

You need to replace the lens, we have your lens repair available on our site for about $75! If we can help please let us know.

I have two Canon Power shots---the A610, and the A630. The lens cover is starting to hang on my 630 when the lens retracts.

If the lens is extended, take your fingertip and try to move the cover a bit to see if it springs open. If not, then the mechanism within the lens needs to be replaced.

Canon makes a great camera, and I would tell you to try to have it fixed if it costs less than 75 dollars. At 75-100 dollars it's a toss-up. More than a 100 dollars---it's your call.

Since you have already tried the basic steps just try to apply some pressure and check. If the lens still do not open up you need to get it repaired from a tech shop.

Thanks

there is a defective flexwire inside the lens or unfortunately the opening or fstops motor is defective. flexwire is easy to repair but a replacement motor is not available or hard to find, (the magnet inside the motor is slowly disintegrating causing it to stall)
