I droped my canon sd 950 is digital elph titanium,from like 4ft and it says lens error,restart camera? What can i do?

Try the procedures in this tip.

You may have gotten dirt or dust into the lens mechanism. Sometimes an air cleaner can help the situation.

This is probably THE single most common failure among digital cameras. There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

its a lens assembly problem, it might be damaged from impact or may be something like dust is making diffficult for it to work u have to take it ti service

Was the camera dropped or has it been exposed to sand dirt etc?

Try these procedures.

Dear ashlyw:

A lens error due to impact damage most often requires service.
If you get an E18 message or a "lens error restart camera" message on your LCD screen and you restart the camera several times to no avail, you will almost certainly need to call Canon Tech Support at 1-800-828-4040 and have it sent in for service as there is little or nothing you can do to resolve the issue.

Hope this helps.

Sincerely,

I have the same problem. How do you restart the camera. I have pulled the battery and SD card, but can't get to a menu screen to restart to camera.

The following blog outlines some repair options for a lens error:
