Alright i got my baby today, and since i've wasted alot of time reading 40D problems threads, i' decided to test my 40D, here are the results.

i suspect the mirror going up and down causes vibrations and it gets soft pics, so i decided to test it ;).i picked up my tripod, focused ONCE, and then set it to manual for both pics, i was also using timer on these.

fulll picture with mirror lockup

Nice -- a very useful exploration of mirror-lock! Now you make me wonder if the IS would helps at all to suppress mirror-slap.

my 70 200 L IS has tipod dectection and i did tests with it on / off on my 350D, and i saw no diference, and here i see exacly the same... it doesnt supress shake at all.

ok so when you peek into the viewfinder or "hole" and u see the picture, you're looking a mirror, and when u shoot, the mirror gets up ( so the viewfinder gets dark ), and back down.

to enable it go custom functions C.fN III : autofocus / drives function 7, if you put enable, when you press the shuter button the mirror will go up, and when u press it again it will take the picture and come back down.

Flips the mirror up prior to a shot well before the shutter opens for the purpose of reducing vibration (causing motion blur).

You can enable it via Custom Functions. I don't own a Mark III or 40D, but you can also use Live View as a means to trigger MLU.

Thanks! Do us all a favor and perform the mirror lock-up vs. no mirror lock-up test with the 10/20/30D, 5D, and 1D series and report back.

Mirror lockup is the process of flipping up the mirror which is located just in front of the sensor. When an SLR takes a photo, the mirror (which allows the photographer to view what image the lens is taking) flips up and the shutter opens allowing the image to be taken. When the mirror flips up, it causes a bit of vibration. This vibration is unnoticeable at higher shutter speeds but at lower shutter speeds can cause the image to be blurry.
The mirror lockup function flips the mirror up when the shutter button is pressed down. The photographer then depresses the shutter button to take the actual shot. This will reduce vibration on the camera. The downside is that the photographer cannot see what he/she is shooting because the mirror is flipped up.
The mirror lockup function is under CFN III on your 40D.

so you are stating that it's completely normal to have shacky/blurry shots ?
this is not aceptable at all...

these weren't 30 seconds exposure's

from my experience with the 350D, this has never happened to me, neither on my friends nikon d200 and 5D...

and from here : http://www.northlight-images.co.uk/Canon_40D​.html (external link)

29th September Is there a 'vibration problem' with some 40Ds?
It's just I received a report of some 40Ds having a problem sometimes after pressing the shutter release. This came from Japan and appears to have lost quite a bit in translation, so if anyone has any additional info I'd welcome an email?
From the report I had it seems Canon replaced faulty items pretty quickly, but the whole report was sufficiently vague that I can't be sure what it's about?? ;-)a"

you feel pretty secure with your 40D, since you're OK with a dead pixel on the LCD screen, and who knows what else.

Mirror lockup is a pretty standard practice for tripod use.

these weren't 30 seconds exposure's

30 second exposures won't show mirror slap fuzziness. The amount of time the camera is shaking is a tiny fraction of the total exposure time. In a short exposure, that fraction is much larger.

I'm saying you can find something wrong with anything if you look hard enough. Sad but true. Your test doesn't prove anything we don't already know. MLU reduces shake. And?

Of course. How else will I be able to make myself feel good about spending my money on inferior equipment? The 50L is in the loving hands of a fellow board member and is doing just fine. ;)

Unlike some people, you can go back and view images I've posted and see that most of them, with the exception of a few, are what I create with these so-called "not acceptable" tools. I let my images speak for themselves, and I'm not talking about pictures of rulers, newspaper articles and Canon boxes. ;) I guess this means I'm content with mediocracy.

yes that's why 30D is sharper than some 40D's.

one of those problems is Right on this thread:
