Having problems with your Canon EOS 40D Digital Camera ?

How do I change the aperature in the manual mode. As I change the shutter speed using the top dial, that works fine however, I'm having trouble using the dial on the back to change the aperature. What should I do?


Answers :

Make sure that the power switch is in the correct position.
It actually has three positions:
\012
    \012
  • Off
  • \012
  • On (with quick control dial disabled!)
  • \012
  • Third position (quick control dial enabled!)
So, when the power switch is in the middle position (ON), the rear control dial is disabled in order to save you from inadvertently changing the setting, when you are wearing the camera on a neck strap.
So be sure to put it in the third position.

Intermittent problem The camera works fine for awhile then the 4-way selector suddenly will not change the menu. Or it gets stuck on full flash or no flash. The selections may get mixed up. The review won't activate except for the last shot sometimes. Then if you leave the camera for a couple of days it seems to fix itself. Everything is fine then suddenly all the troubles come back.

Hi, I've just recieved my nikon d90 back from a repair and service, and although everything appears to be working fine, whenever I want to change shooting modes,( auto, P, M, flash off etc), they only work once I have selected them, and then turned the camera off and back on. In other words I cannot be shooting in the Auto mode and then switch to "flash off auto"....all that happens is that the auto focus works but the shutter will not operate. If I switch the camera off and on however, I can t

Grinding noise I had my cd500 fixed in November. The little piece that holds the cd in came off. They fixed that, but then when I got it back I was still getting format errors. They gave it back and told me to only use mavica discs. And since then that is what I've been doing. However I am still hearing a loud grinding noise when the picture is being burned. Do you know what it is? I am wondering if I need to take it back in.
