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


A camera is a very complex device so any internal damage would need a proper repair, it may only be a disturbed internal problem but with fiddly screws and the need to keep dust free a good repair place is needed.
As for you just check and refit any items you can like a card or battery etc, if new and bought with a credit card there may be an insurance on it or you can call on or contents policy maybe, as there are lots of policies on new items for a short time in respect of damage claims.
If a cheap cost to purchase and not worth the cost of repair then auction on ebay to recover some money.

Sorry, hope that helps you decide..........

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...

If lens has AF/MF switch, make sure it's set to AF. Check/clean connectors between camera and lens. Try with good light source.

Have you checked camera battery with voltage tester to see if it is charged fully and if not charge battery or put new battery in. Rich

When showing busy, most of the time the camera detected an error, but can't find out what is causing the error.
Try the normal "reset" method as follows:
Like a cold boot for a computer, the camera can be "rebooted"
follow the following steps:
Switch of the camera and remove the battery.
Remove the memory card and the lens. (if possible)
Recharge the battery. Wait till the indicator on the charger indicates the battery is fully charged.
Check all contacts, if they are clean and shiny. Contacts (from battery and memory card, only to be cleaned with a dry cloth or cotton swab(s).
Reinsert the battery, reinsert the memory card and re-attach the lens.
Then switch on the camera.
If this does not help, contact a certified Canon repair centre.

Err 99 Some other fault.
There is something wrong, but the camera does not know what.
This number is for all errors the camera can't handle.

How old are your batteries, and are they Canon brand or a cheap eBay type off brand? Most times we see this the batteries are old and won't hold a full charge or are cheap off-brand ones.

Has the camera been exposed to intense moisture or fallen into water. Water damage can drain a battery quickly.

There is a software adjustment to set the battery inhibit voltage, but you will have to take your camera to Canon as it is proprietary software only they have

also check for bent CF pins

Tr5y a factory reset on the camera. And try another Memory card.

Sorry I only have a such manual, but on the drawing it says Focusinstellingsknop (pag. 30).
That switch, on the lens, should on AF and not on MF. Did you check that one?
All EOS lenses do have such a switch.

Not sure in which context this refers to but it could mean the resolution of your image 600 pixel by 600 pixels.

No there isn't Ian. What lens are you using just out of curiosity? There have been the odd issue with Tamron lenses causing error 99s constantly. Check your firmware just to be on the safeside - and keep it up to date if you can. Firmware is designed to iron out little kinks such as errors and other anomalies.

It may be the lens try a different lens at your nearest photography shop as the auto focus is usually a lens problem. other wise try resetting your cam remove all batts including the lithium one and the CF card wait about 20mins then replace if prob still persists then try again without any lens and see if it trys to focus and make sure the shutter is working if its ok so far then u need to try a new lens at local shop and then if it works the body is ok if not then it needs a service!

Did you remove the USB cable? As long as there is an USB cable in the camera, you can't power it up.
Then you still have to check if the battery is still in good order. Batteries do have a limited time of life. And you only can be sure it is charged, when it works in another (same model) camera.
