Question about Canon EOS 40D Digital Camera

3 Answers

EOS 40D died without obvious reason.

I was using the camera in the morning. When I came to switch on in the afternoon, there was no response from the camera. I recharged the battery and cleaned its contacts, but to no avail. Suspect circuit board is burned out.

As a camera repairman with 35 years of experience repairing all makes and models of cameras, I have done several EOS 40D's with this issue. The problem is one of the two motors in the body, 1 for mirror shutter charging 1 for flash head up has gone bad. When the camera is powered on the microprocessor pulses the motors for 20ms to check the battery. The motors in this camera are an extremely new design that are breaking in sometimes a very short time. Just did a repair with a shutter/mirror count of 2370 on it.

Some problems such as suspected circuit board issue will most likely require a return to the manufacturer.

Is the canon eos 40d,the same as the canon 40d,if not whats the difference,can you answer please


They are the same thing. There is only one Canon EOS 40D. If you've seen it listed differently it's just that they've left out the EOS prefix. All Canon DSLR cameras are named EOS.

Switched to MAC - have EOS40D and SX100 - will not download SX100


Yes, you need to install the SX100 driver software as well. I wouldn't overwrite older versions of the Canon software, though, so do a selective install if you can.

Firing "lag time" response


Hi poseguerai, 
Try this:
I had the same issue and even if it sounds crazy giving a massage to the shutter button all around in circles helped and when you switch on the camera has no shutter lag again.
I hope it works as it did for me.

Canon 40D can not turn on


Same problem. Fully charged main battery. In my case, I hadn't used the camera in over 6 months. All I did was pull the main battery and then pulled the small CR 2016 button cell battery located inside the main battery compartment and re-inserted both batteries. The camera made a quiet click and then turned on with the main power switch and asked to reset the date and time. Works fine now. If this doesn't work just purchase a new button cell.
