Top 20 Canon EOS 400D / Rebel XTi Digital Camera with 18-55mm Lens Questions & Answers

check for corrosion on your battery's contacts. If that's OK try operating your camera with the lense off. If succeeded, you should try and fix your lense (do check if your camera wasn't damaged by it too).

I had this problem and thank you to the gent that suggested there was a battery compartment closing detection mechanism. I have a battery grip and had removed that to register my t2i (needed the serial number on the bottom) and never checked operation after replacing. I toyed with the lever using a pen and noticed the red light flicker. I replaced the battery grip with batteries and all is well. Sometimes we need a nudge to dig deeper... I had looked at the possibility of a door closed switch much the same as the the switch on the sd card door. I took a second look and found it. Thanks a million for jogging my analytical brain!

This is usually caused by impact or sticky liquid spillage on the flash causing it to stick down. Lift up on the flash head when it clicks to free it and then used a Qtip soaked in water or Windex to clean around the flash. You may have to disassemble the flash and clean the pivots -especially the pivot screw if rusted (scape off the rust with a Xacto blade and then lightly coat with grease)

Yes, it could be an issue with the camera or the battery. The easiest way to find out is to try a different battery in the camera. If this works then the most likely culprit is your battery. If this doesn't work then your camera requires service.A good camera store should let you try one of their batteries in your camera.

usually this is caused by putting the card in sideways. you can usually see if pins are bent or pushed through (loose floating around inside) and you see an empty black rectangle where the pin should be.pins are soldered to main circuit, and the XTi uses lead free solder which requires skill to repair. this is repairable but would run you somewhere in the $150-190 range

You don't need any special software to use your camera.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, despite what I said first, you can use any photo cataloging program, such as Picsaa.

Sorry to hear about this. I have a similar camera and have been racking my brain about this...

My only thought...are you using the same battery charger? Perhaps the battery charger is to blame. You may be out of battery on both batteries. When you install the battery, does ANYTHING happen? Does it say, LOW Battery or CHANGE the battery? Or is it totally black? If nothing happens at all, you should probably contact Canon directly. Or purchase a new charger and see if that fixes the problem.

SD cards come in different levels. If you look at your card there should be a number on the front of the card. the higher the number means the faster the card. If you have a level 6 card then you shouldn't have the problem of getting a busy signal. your photos are large files and if your card is slow ie a level 3 then it takes time for the data to copy to it. So find yourself a level 5 or 6 card and you shouldn't have this problem.

Hiyou might have a problem of either main pcb or power control pcd (dc/dc convertor). it is common but it cost. It cause usually come from loosen screw going around inside and short. If it is lucky, then your unit would just a fuse brown. If not, it has to change main pcb and all of computer adjustment is involved. Your local repair shop would charge you around $65 to 235.

read the below website on aftermarket lenese for Canon.. It may shock you to purchase a genuine Canon lens instead

Hi. I can give you some advices, but be very careful!

What do you have to do?

Clean (very carefully) the 8 gold color lens contact pins on the camera body
lens mount. Be sure that you're doing good.
Remove your CF memory card and take out the camera's both batteries (the main one and the smaller date/time battery).
While the batteries are removed, turn on the camera and let it for like 5 minutes.
Turn your camera off and attach your CF memory card & your batteris where it belongs. Also, re-attach the lens. Turn your camera on.


You can also update your firmware!


I hope it works!

Mcm,
Trying taking a Q-tip with some alcohol and cleaning the contacts inside the battery chamber. Also, you can take it to your local camera store and ask them to try it with one of their batteries to rule out if yours is dead.

Thank you.

I have read quite a lot about this infamous Error 99 on the Internet. Rather than try to summarise or duplicate the information here, I'm going to point you to someone who's already done just that, from bitter experience, I think! There's a very comprehensive essay about the various possible causes of Error 99 here (follow link).

Welcome to Fixya
Err 99 could means 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.

Most Canons don't seem to be able to embed the date on photos unless the resolution is set to "postcard mode", which is 1600 by something pixels. Set to that resolution, and then try to set the date mark feature (it will be greyed out when the resolution is not set to a compatible mode).
