In the menu of my Canon 450D I am missing icons: The shooting (camera) icon, the 3rd icon (spanner with 3 dots) and the star icon (my menu) Is there any way for me to get these icons back? I only noticed today when I went into menu that they are missing and am not sure who did it or who played around with my camera. Thanks in advance for your help.

Do you have the dial set to either P, Tv, Av, M or A-DEP? It will only work in those modes, and will probably only be in the camera icon menu when the camera is set to one of those modes.
Hope that helps.

The only way to have the Date directly on the photo is to change your picture size into postcard mode. do that by hitting function set, and going to the bottom of the options where you choose your picture size... after that do what you described above, however the option will not be greyed out... that will put the pictures directly on the photo... warning!! the reason they make it a pain in the rear is because it will be on all pictures all the time.. no way to remove after!!! you can get several photo programs that will let you insert the date on only the pictures you choose.. Or you can go somewhere other then walmart where the technicians aren't required to have them ready in an hour... yes.. speed isn't always best... and they should be able to choose it in there settings... because the Date is always in your file Data... just not being displayed.. Or go get a little photo printer and print the ones you want... average cost.. 30 cents.. a little more.. but you have the control!! and you don't have to burn and gas while doing so!! Cheers

It sounds like the image stabilization "on" indicator.

SOURCE: Canon 450D, ERROR 99 only when flash pops up

Err 99 usually means your lens contacts are dirty either on the lens itself or on the camera.

To isolate the cause of the issue, do the following: -
1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert only a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, the camera may be faulty and requires a service. If it does not, then: -
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, then the CF card is faulty. Try a different card. If the message does not appear: -
1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.

If the “ERR 99" message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99" with a different Canon lens attached, then the camera is faulty and should be serviced.
