Having problems with your Canon EOS 40D Digital Camera ?

Sometimes, when I take a picture with my 40d the automatic shutter speeds that display can fluctuate dramatically from 100th of a second to 10th of second in just a split second before I press the shutter, leaving me with an overexposed picture. Why does this fluctuation happen?



Answers :

Your camera is probably set to SPOT exposure instead of AVERAGE exposure,. Which means, your camera is taking readings from a smaller area within the frame instead of using the whole frame to decide exposure. When in spot exposure you can move a hair and the exposure will change dramatically. does this make sense? put your camera back into average metering.

Cannon EOS500D, taking a picture in creative modes I have to press the shutter button twice to take a picture.(not counting the half pressing of the shutter button. the second pressing of the shutter button can be any length of time to take a picture.

On my Sony Cybershot DSC-P8 camera, the shutter will not operate when I press the shutter button to take a picture. Everything else seems to be working. This happened all of a sudden. The camera took about 8 pictures, then after turning it off for about 2 hours, it would not take any more pictures. This happens even after I push the reset button, take the battery in & out and the memory stick in & out. I have not had any problems with this camera until now.

This is a recently purchased camera that was working beautifully until recently. It just stopped taking pictures; when the shutter release is pressed, nothing happens. The only clue I have to what is happening came when I pressed the Quick View button and got a No Card message. I changed the CF card to one I took from my Canon Rebel XT and that I knew was working fine - again the message No Card when the QV button was pressed. Does that help at all in defining the problem? Any ideas what the pro

My Canon SD950 IS camera will take about 30 seconds to take a flash picture. You have to hold down the shutter button for a long time. The flash indicator flashes on the display for quite a while and then the picture is finally taken. This seems to have happened after the battery was run down to nothing. After that, this flash problem appeared. I have got another battery but this still happens. I have reset to default settings as well . Still has problem. What is wrong?

I have a Polaroid Impulse QPS and it won't turn on anymore. Usually to take photos I open the flash and a little red light comes on next to the button that you press to take a picture. In a couple seconds it turns to green and I can take the picture, but all of a sudden the light stopped going on at all. so when I press the button, nothing happens. I was thinking maybe it's a battery problem, but I can't figure out where to put batteris in the camera! I got it used, so I've never done it be

When I switch the camera on the screen stays blank even though the lens comes out, it eventually goes off (with the lens still out after about 40 seconds). I can get the camera to work if I press the green "view" key and then, after the picture appears, press the red camera icon and it will go into auto shoot mode. Happens every time now. I can't take it in under warranty as it was a present and I don't have the receipt unfortunately.

I've owned this camera Nikon F65 for a few years and it was working perfectly, but I haven't used it for the past year or so and now it just stopped working!

Pictures a very overexposed. Inside I can shoot without a flash at 400 ISO and they come out right. Outside they turn white. Also the shutter speed won't register. I can set it at 125 or even 500 and it comes out at about 1/30 or 1/60 of a second. Lower shutter speeds are actually lower. This happened a day after I cleaned my sensor. Could that be the problems?
