Camera shuts off when you click the shutter button

This is a common situation with compact point&shoot cameras. Between the time you press the shutter release button and it takes a picture, it has a lot to do. It has to find the subject and focus on it, meter the light and set the exposure, perhaps set the white balance, and other things. Larger, more powerful (and more expensive) DSLRs have more powerful processors and additional hardware to speed up the process.

One way you can reduce this shutter lag is to press the shutter release button halfway to focus and meter before you need the picture. Keep the shutter button pressed halfway until the action hits its peak, then press it the rest of the way.

You cannot take a picture when your camera has not been focused yet. This is done by pointing your selected focus point on your subject, then click the shutter button halfway / half-pressed until you here a beep or see a dot on the lower left portion of your viewfinder. Once you have locked your focus, press the shutter button all the way down to take the shot.

A few suggestions: The mirror lock up function has been activated. The sensor cleaning mode has been activated, doing this the camera as soon as you trip the shutter the mirror will come up and all other functions of the camera are inoperable. the mirror will stay in that position until it runs out of battery or you turn it off. The part you said about having to removing the battery doesn't make scents for this function though. Sensor cleaning is in the Custom Functions.
I know you said regardless of lenses and batteries how long do you wait before shutting the camera off and removing the battery? I know that's a question and we aren't suppose to answer a question with a question but the reason I'm asking is that the Canon 40D has a long 30 second shutter speed and a "bulb" setting. It is possible that the camera has been set to "AV" and the shutter is timing out, OR it's been turned to BULB and that mirror will stay there until the camera battery is dead before it drops. Couple things to check out before the next thing I'd think about is the amount of shutter actuation. The Canon 40D has a shutter good for 100,000 clicks/actuation. Sounds like a lot but if you are doing time laps or extended video it's very possible to blow the shutter out of these.

Sounds like a loose screw inside shorting out one of the curciut boards! tccamerarepair.com

Your fix could be as simple as cleaning the camera's battery contacts, or it could be something more serious and expensive. Before you pay for expensive repairs that you may or may not need, check the Kodak Help Center by clicking on the link below. It uses a simple Q&A format to diagnose problems and propose solutions.

This sounds like it might be a defective CCD imager. If so, Sony should fix this for you for free, but it will cost you $15 shipping. This is regardless of your camera's warranty status. Please check the following link for more info:

There is something wrong with the settings of the camera.
When it is on setting or view mode is fine. It is not supposed to take pictures.
Go thru the Menu and pick the way you want your pictures, size and all those details, switch them take pictures and keep switching the settings until you get it right.

My camera was taking 3 pictures at the time, and it was because of the setting was set to do that. Don't be afraid of changing the setting for pictures, you can always change and try different things, digital pictures can be erased right away. So you can try as much as you want.
Try all options in the setting for taking a picture, change a setting, try to take a picture and see what happens. Then try on another setting and so on.

I assume so...mine is doing it as well. Even weirder is you hold a combo of buttons (i think power and mic, I dont remember exactly) and you can go into this manufacturers menu for setting up and testing the device. In that, it will take pictures and everything...and still i cannot get it to stop shutting off like that. It makes a weird clicking noise when it shuts off too...sounds like the shutter perhaps. Click click. If you find a solution to it please email me at [email protected]
