Makes me wish Canon made their battery doors and grips like my old Minolta (the grip had space for the camera's battery door still attached in its native position; no door removal necessary).

I just ran across this posting where I have to say that my 40D
gives me fits with the shutter button. It is very frustrating
because sometimes the camera requires me to really press down hard on
the shutter button where this extra muscle exertion/movement causes
unwanted camera shake. Sometimes I even have to press the
shutter button down a couple of times very quickly where it causes me
to loose that one moment where I need to capture that perfect image.
I have tried everything besides sending it in but it does it so
randomly that Canon may think I'm crazy. I've noticed that this
glitch happens more when the camera is presented with lower light
situations but it always does it in the worst moments. I've gone into
the custom menu and played around with some of the functions like
"Lens drive when AF impossible" Focus search on, where
sometimes I think it's helped but other times I say crap.
I have my camera set up where I use the back exposure lock button
to set focus. I had to switch the operation of this button with the
AF-ON so that my BG-E2N battery grip would operate in the same way.
So with this set up the shutter button when pressed half way sets
exposure and when you press it the rest of the way the image is
taken. Whether my camera has the focus set or not as determined by
the green dot in the view finder the camera will take the picture, so
this issue is not related to the camera not taking the picture
because it thinks it has not achieved focus.
It addition the camera's shutter button does not feel as smooth as
when it was new. Another related issue that I feel is different
about the camera is that it seems like your finger has to be directly
in the center of the button where you have to press in a perfect
downward motion. I understand that this is the way buttons work
but it did not require this in its first year of service. When
the camera was new it would snap the shutter if you blew on it. I
rely on super sensitive buttons/controls because I am a
photojournalist/sports photographer where I am usually running around
by the seat of my pants, sweat dripping off my head, sweaty
fingers/hands, and all. Moments happen so quickly that
sometimes I'm not usually set up waiting for them. Most of the time I
am moving around and scanning with my eyes where I pop my camera up
and need a shot in as little time as possible. My trigger finger
usually floats back and forth between the grip and the shutter button
where at times it isn't in the perfect alignment with the button.
My camera's is in perfect condition where I take excellent care of
it but it has seen some drizzle and very dusty conditions through
it's service. One answer may be that I just need to spring for
the pro body. Someday soon hopefully Canon will make the 1D Mark 4
with all the additions of the 50D/5D Mark 2 plus retain the higher
end buttons and switches. This would be the better option for me
then upgrading to the 5D Mark II. The 40D has been a great camera but
this button issue is very frustrating! I also have a 30D that has
seen a lot of use and it does not do this.
Do any of these problems that I mention sound like the ones that
you are having Sinh Nhut Nguyen?
Send it in. Canon's going to look at the internals, and most likely replace the shutter switch as part of their repair estimate. Besides, as I've been told by Canon, if you send something to them for repair, and you decide you don't like the estimate and want to skip the work, they pay to ship the gear back to you.
Rumor says the 1D4 is coming soon, though (since it's rumor) the specifics are still hazy.

BThornhill: I would send it in to Canon, fix is about $180-250.
Here's the quick fix that I've tried and it's worked both time (however read above for my comment on the battery).
-Turn off thecamera
-Press the button for about 20-30 times
-Do a circular motion (twisting) every time while the button is being pressed down.
Try those steps first, then try the battery. If it works, it will work for a while, problem will occur again because the contacts beneath the button are dirty and the only way to permanently fixthis problemis to open it and clean it. Good luck and please let me and others know the result, thanks.

<p style="margin-bottom: 0in;"]Thanks for the two responses
considering my post. This problem is most likely from the
accumulation of all the dust and moisture but the only kicker is that
my 30D has seen a lot more dust and moisture as well as shutter
actuations and it's shutter button still works flawlessly. Side note:
Those where some pretty good macro photos that Tobben posted of his
dismantled camera. Great job Tobben and thanks for posting them. I'm a pretty bold individual where I've
taken apart my 17-55mm IS lens to clean the dust prone front element
but his tear down of the entire camera body looks insane.
Add me to the list of people with the shutter button having intermittent issues. My 40D was purchased in August '08. Occasionally (more often now) I have to press it all the way down and hard for it to work. Such force on the side of the camera causes motion blur, and is really annoying.[:@] I'll try all of the suggestions mentioned in this thread, and post here later with the results.
I finally have had enough with my 40D shutter release button problem. So I brought it in to Canon and the charge is $180. They also clean your sensor and mirror while they're at it, a $30 value (used to be free though).
I will update you guys when I pick up my camera.
Nate,
Got a call from Canon yesterday and went to pick up my camera. They cleaned and changed the shutter release button unit and also the main board (whatever this is I don't know). Everything was $180 and I was left only one day without the camera.
Wow, that was super quick! I'm happy for ya Nate.
Did you ask why the hell they had to replace the main board?
I did ask why, the receptionist didn't know. He just said, the technician also replace the main board, a $67 value, which I got for free []
