Canon error code 99

Hi there! I just bought a Canon 400D and tried to use a zoom lense from my old Canon SLR, but can't take any photos - 'error code 99, turn camera off and on again' - that doesn't work, though. Camera works perfectly with 28-55 lens that came with it. Why does the old lens not work? Thanks for any help.

Re: Canon error code 99

Your camera performs a quick 'integrity' check before each shot and goes into error 99 mode if the lens in incompatible or has a diaphragm problem. ( it will also display e99 if the shutter or flash unit is not ok but this does not apply here ). This is how you can check whether the diaphragm mechanism is ok : attach lens to your old camera and set camera to AV and set F stop to 16 . open back and release shutter and look through the back to see if your lens is closing to F 16. If it is closing fine then the lens is ok but is not compatible with your D400.

On my EOS 400D, my view lense cannot use as a view finder.

The 400D does not have LiveView capability. You have to look through the viewfinder, as SLR uses have done for half a century.

What is error ''99'' on a 400D

error 99 on a 400D is a problem with the lens contacts this is what the canon people say to do read this!!

The guy at tech support listened and then told me that the lens contacts were dirty and to get a pencil with an eraser on the end, just a regular old pencil with a red rubber eraser. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them.

Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly. I used a lens cloth and dabbed at the contacts rather than blow them so as not to blow the erasings inside the camera.

I did this to each of my three lenses just to be sure. Lo and behold, it worked

hope that helps!!! have a good day!!!! :)

Whats the best economical lens to use for indoor photograph with

If you are new to photography in general and especially SLR photography I would suggest holding off on buying any lenses besides the 18-55mm.

The reason I suggest not buying extra lenses just yet is coz you need to get to know your camera and if you are new to SLR photography then you need to get your fundamentals right. Sure the 400D will let you shoot in full auto mode but you will really not learn much doing that and certainly not be making the most of your camera in that process and that will extend to your new lenses too.

Get used the the control, the 18-55 is a great little cheap lens with the pop up flash it will work great for most family pics. The 55-200mm is a new "cheap" lens, its been marketed as letting you go beyond 55mm thats why it starts at 55mm goes to 200mm.

Hope this helps you...

I have a digital slr 400d canon camera. It is getting the message error 99 after taking a few pictures. what can I do to get rid of it?

Hi There,
on these models the 99 code is generic, and can mean a bunch of different errors, but usually it is dirty contacts. It can be on the battery, or more likely between the lens and camera body.

Check out this link here, there are a lot of good things to try.

Good luck. And don't listen to the comments that Canon is bad, I have had Canon's for years, and they are great cameras!

Cannon Eos 400D Err 99?

Error 99 is a NONSPECIFIC error message. It is almost always associated with the LENS. I first got this error on my EOS 20D whei I tried to use an older Sigma zoom lens (7 years older than the camera). I don't use off-brand lenses with my Canons. Try removing the main battery first followed by the time & date battery which is hidden in the battery compartment beside the main battery. This will reset your camera. Good Luck!

My Canon is displaying - Err 99 what should I do?

This can mean a host of different problems but try these things to fix it:
  1. clean the lense contacts as poor conection between the camera and the lenses can cause this. Also clean the contacts on the body of the camera.  The contacts should be cleaned with a plastic eraser, but make sure it is clean before using it.
  2. Clean the battery contacts (on the battery)
  3. Change lenses and see if you have the same problem (does it only have this problem on one lense?)
  4. Make sure you have the lates firmware installed.
Don't swap lenses while the camera is writing to the memory card, lots of things like this can cause this error message. Also the flash can cause it.
Usually the lense is the culprit so make sure it is fully cleaned.

Error 99 in canon 400D

You will get that error when using some lenses other than Canon. A lot of the older Sigma lenses have that issue. Do you get this error when using newer Canon EOS lenses?
