Canon IXUS40, rubber(?) seal between lens rings & body keeps popping out

I have a Canon IXUS40. The rubber(?) seal between lens rings & the body keeps popping out. Is this something I can replace myself? It started to happen when I was travelling somewhere extremely hot. I suspect the heat expanded or softened the ring so it became over-sized for the original diameter, or the adhesive keeping it in place melted. Thanks.

It can be replaced, but requires removing the front face of the camera. Here's an example disassembly. Proceed no further than removing the front face to install the seal:

Not sure where you could find a replacement other than from another (broken) camera. The seal is mainly intended to minimize sand and grit from entering the camera, but is not necessary for operation of the camera.

The camera turns on the lens dont return back into the camera

This is a typical lens problems unfortunately.

If the lens is stuck at an angle like the leaning tower of Pisa, then you can try to "snap" it back towards the middle to straighten it out. This is done at your own risk. Hold onto the larger ring of the lens, the one closer to the body of the camera and place the round edge of the outer section of the lens against the edge of a table or counter. Now apply pressure on the lens, pressing it back towards the middle. Hopefully the guide pin that is out of its track will pop back in and everything will work properly again!

If the lens is not at an angle, it needs to be replaced, that's the easiest solution because trying to rebuild one of these lenses is extremely difficult. You would be best off dealing with Canon directly for this repair! 1-800-OK-CANON

The f stop say ee

You're apparently using a lens with an aperture ring. Turn it to its smallest aperture (largest f/number). You control the aperture from the camera body, the same way as on a lens without an aperture ring.

If the lens doesn't have an aperture ring, clean the electrical contacts on the back of the lens and in the lens mount.

HI I have a cannon eos digital SLR. When I try to take a picture error 99 appears on the screen. I do not know how to correct it. Will I have to send it back to the cannon company? Is there someway I can...

Error 99 and believe me I've been there is Canon's catch all error code cause if the camera can't figure out what's wrong it goes to Error 99. Canon doesn't release any information directly towards error 99 due to several different causes. That was the bad news. The good news or at least the better news is that most of the time error 99 is caused by dirty contacts between the camera and lens. At least this is the problem I'll address in this solution.
You will need a new pencil with a red rubber eraser, make sure the camera is turned off, remove the lens from your camera and put a body cap on. If you do not have a body cap lay the camera lens mount face down on a clean lint free surface. Take the lens and hold as vertical as possible with the rear lens element facing down and turn the lens body so you can see the gold contacts. Use the red rubber eraser to gently clean the contacts. Make sure they are clean and all rubber dust is removed from the lens and contacts. on the lens you may use a little puffer/blower or a lens cloth not a tissue. Do not use a liquid cleaner. Once you have finished the cleaning of these contacts either put a rear lens cap on or set the lens where it is not going to get knocked over sitting on a clean dust free surface with the contacts down. Now take the camera and as much as possible keep the lens cavity pointing down to eliminate any rubber dust from entering the camera, clean the contacts again gently with the rubber eraser clear the dust with a lens cloth not a tissue DO NOT use a puffer/blower at this point because it will only blow the dirt into the camera. Once you are satisfied that area is clean reinstall the lens make sure it's locked and turn on the camera. You should be "Good to go". Well lets hope so anyway. Error 99 can also be a problem with third party lenses like Tamron, Sigma, Tokina not having the up to date electronics to match your camera properly Error 99 can also be caused by requiring a camera firmware update but for now lets just go with cleaning the lens to camera contacts.

I have a canon eos Rebel DXS - I dropped it and now it won't focus.

Normally I'd say your camera is due for a trip to the service department but, depending on the surface the camera was dropped on and did it hit lens first or body. So without knowing let me ask you to do this. Remove the lens and quickly install the body cap on the camera. Hold the lens firmly in a hand and shake it vertically gently but with a little vigor listen for a rattle, stop, do it again horizontally listen for a rattle. If it rattles the lens has internal damage if not and the camera appears to be functioning then I'm going to instruct you on how to clean the gold contacts on the lens and body.
Using a new pencil with a red rubber eraser gently rub/clean the gold contacts while holding the lens almost vertical with the contacts facing down, use a puffer/blower to clear away the rubber dust. On the camera body, remove the body cap and hold the camera with the lens mount facing down as best possible and clean the tinny gold contacts with the red rubber eraser. DO NOT use a puffer/blower or blow on this part to remove eraser dust. Keep the camera lens mount facing down as much as possible and use a lens tissue to clean away any rubber dust. When you have completed this install the lens on the camera and make sure it clicks and locks solidly. Try your camera again, if it works great if not it means there is an electrical break within the camera or lens and it needs to got to a service depot. Hope everything work for you

Error 99 for canon 350D

Error 99 says on the canon site to upgrade your firmware, so I did that, still no joy. Then i read on this site to clean the contacts between lens and camera with a soft eraser...worked a treat. No more err 99 and I will be keeping the rubber in my kit!!

E18 error on Canon ixus40 - lens stuck

The E18 error is an error message on Canon digital cameras. The E18 error occurs when anything prevents the zoom lens from properly extending or retracting.[1] The error has become notorious in the Canon user community as it can completely disable the camera, requiring expensive repairs.
A quick internet search for "E18" + "canon" quickly reveals hundreds of similar complaints. reports that the "lens has a feature called bellows claw, which is a gear that physically extends and retracts the lens. A piece that holds the lens, the barrier plate, is not large enough and can sometimes cause the bellows claw to malfunction, resulting in a stuck lens". The result is a black screen that only contains the error message, E18. Another problem mentioned on the site blames a sticky iris in the lens, caused by grease entering inside from the microphones built into the lens. The buildup freezes up the ability of the lens to open.

Lens is jamed

Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:

Error 01

What camera is this?

If DSLR, that out the lens from body. Look into the lens, is aperture is closed or opened? It should be open on Canon and open or closes on Nikon(make sure you can turn the Aperture ring).

SD Card capacity and make problem with IXUS40/SD300

Basally, you are not limited with the SD card capacity. It is an "economic" decision only. Sandisk is one of the best companies for it.
