20 Most Recent Canon EOS 400D Digital Camera Questions & Answers

This error message is common to a broken lens ribbon problem. Does the lens work in manual and not in auto. If so it could well be the problem. The fix is to have the lens ribbon replaced.

Dear! It would be easy or very bad. First you can check your memory card pins bent in receptance unit. It is hard to see. You should use flash light with magnifying glass. It not the problem then mostly like some loosen screw running around and shorting the circuitry. One of these is very common problem of a certain canon product. It is an engineer defect design. It should be factory recall problem but no they don't recall the problem. Both problem solving need some delicate skill. They need both disassemble! Hope you luck! A Professional Camera Clinic Guy!

What wide angle lens is it need f number it may be to old to work on eos 400d

If it is just one Flash card, then the card may have failed. If however you have tried other Flash cards and you get the same problem then one of the contacts (small gold coloured pins inside the camera that mate with the Flash Card) may have bent causing the error.

Take it off green rectangle and set it on P. Then the flash will only pop up if you push the flash button

Poor how? What are you shooting?

Check your battery level, if not, there might be a loose cable inside your camera, or a faulty button. Might need to open it.

just replace card and try or format card your card have some poblem

Unplug the camera if it's connected, then shut down and restart your computer.In the future you might want to consider NOT connecting your camera to your computer. The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa.

Just go to Canon's website where you'll find a section called Customer Support or similar wording.
There you'll find easy steps to getting the manual for your camera downloaded.

Sigma makes lenses with a variety of mounts to fit a variety of cameras. A lens with a Pentax mount, for example, will not fit a Canon camera. Assuming you get a lens with a Canon mount then yes, it will work on your Canon.

Welcome to Fixya
Err 99 could mean several different things, such as... Memory Card, Lens or Lens contacts....

Here's what you can try:
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.
