If someone says that a camera has a problem and ANYONE says that theirs doesn't, they take that as a personal insult on their credibility or question their competence level and they react accordingly. Some people, like Jack, like to insult others into submission if he can't disprove them. It's funny that both Jack and I agree that there are some bad cameras out there and some good ones yet all he likes to do is harp about the bad ones and take pot shots at the ones who disagree. My take on this whole thing is to just go out and take pictures with the camera. If you don't look like they should, check for a problem. If there is definitely one, send it back. It just seems to me that some people want others to run their cameras through a torture test and hope they'll find a problem so they'll have company (as evidenced by Hugo's constant "welcome to the club" posts) in their disappointment. With all this ranting about "bad cameras" and urging for testing until you find a problem, no one can just ENJOY their new camera. It saddened me to see a fellow who'd just got his 10D in his hands be too afraid to even take it out and use it because of all the ruckus these few people have raised.

For the record:
I don't dispute Bill's claim. Looks like he may have a miscalibration issue with his 10D and/or lens.
I don't dispute any of the other dozens of genuine AF complaints; this is to be expected from a production run of several thousands.
I DO have a problem with people who brand the 10D a "faulty" camera based on the small % of manufacturing errors.
I DO have a problem with people who brand happy 10D owners "Canon PRs". I am a happy 10D owner, have run several in-depth AF tests, and can confirm that MY 10D works well.
All things said and done, it's quite comical to read some of the posts that absolutely trash the 10D for micro-millimetre inaccuracies at f/1.8. Do you really expect that level of accuracy from a mid-range camera, especially when these errors will almost NEVER be seen in real-world photos?
Want professional-grade AF? But a 1D or 1Ds.
Have a miscalibrated 10D? Send it in for repair.
Where is all this anger coming from guys?
Best,

Sorry, Mike, I would discredit any tests that are not done on a stable tripod, in good light, with a large enough stationary target with contrast, using the centre point only, with a MF test run along with it. There are too many ways that things can go wrong and it is easy to blame the camera.
Like you've said, it could be you recomposing after achieving focus, or it could be handshake, or it could be the camera moved slightly due to pressure from your finger, or your left hand inadvertently slipping the zoom ring or focus ring a little, etc.

Zero my heroSomething I found when doing my focus test was that sometimes my
hands moved enough that the focus pont was not over what I focused
on. The Canon software doesn't reflect the foucus point accurately
if you lock on focus and recompose the shot.
I ran my test seven times and one time I had front focusing and the
above is what happened. My hands moved. I'm too lazy to setup my
tripod. It is packed away for a trip.

...but it's not unexpected. The major underlying reaction of these "dissenters" is that Canon DELIBERATELY sold them a bad product. I feel that's why they're striking back by trying to make Canon lose sales if they can. This is so sad. Hugo's even going to the extreme of trying to make Canon's follow up service look bad with his blow-by-blow descriptions. Really pathetic.

were talking cm not mm and cm makes a difference if you are using DOF to enhance a subject and are blurring the background or foreground tough to explain to a client why their wife is blurry and the object in front of her is sharp.
ps many people here are complaining that i am using this forum as an oppurtunity to possibly discover a flaw in not onlyMY camera but possibly others
especially "perlrider" intresting thiis person thinks this is all a waist of time yet the subject of these post are self explanatory and there is nothing forcing people to read them yet this person has posted at last check 18 times that 12% of the post interesting?

That's why I placed a card BESIDE the ruler and focused on it instead of the ruler. As my test showed, the camera focused right on target. My wife just got home with her 10D and, much to her chagrin ("That's stupid!"), I did the test again with her 10D and the 28-135. It came through perfectly too. That's TWO 10Ds that I know for certain DON'T have the front or back focusing problem! I'm not saying that ALL of them work properly because the ones I have do but I don't think it's as big an "issue" as some would have you believe. I truly think some of these people, whether they relaize it or not, are actually trying to strike back at Canon by scaring off sales. It's a shame that some people will pass on this fine camera because of the harping these few people do.Try doing this test with a series of flat surfaces that are
perpendicular to the lens, which are large enough to clearly fully
contain the "focus point", and which have sufficient detail to
provide some contrast for AF. The sides of cereal boxes could be
used, or some film canisters. Either put these at varying distances
from the camera or lay them out in a perfect line, and then shoot
from an angle.
The problem with the "ruler test" is that it's difficult to really
ensure where the focus point is focusing on, and how the AF is
going to lock. Providing a broad perpendicular surface clears up
some of these ambiguities.
Also, put the camera on a tripod, use the lowest ISO, select the
middle focus point, use the widest aperture on the lens, provide
plenty of ambient light, etc.
I've done this sort of test with my D60, no doubt inspired by the
flood of "My D60 front focuses" cries that, a few months ago, were
only interrupted by the "My D60 rear focuses" cries. Try as I
might, my D60 never did anything but focus spot on the right target.

Bill, I agree. Seems you have a problem with your 10D. But...do all 10D's have this problem? Nope. Mine doesn't, focuses down to the millimetre (as long as there's enough contrast and light of course). I wouldn't expect it to nail AF in poor light with no contrast, not even the 1D will do that.
My point was that some of the posts regarding the AF issue are way overhyped, with the attacks becoming personal. Overzealous posters who say that NO 10D has a problem annoy me just as much as those that say all 10D's have a problem and all happy 10D owners work for Canon. These are the same people that buy Fords and complaint that their cars aren't built as well as BMWs. Come on!
I'm sure if you send you camera back to Canon they will gladly repair it for you, and you will have a perfectly working, focusing 10D.
Good luck, and good shooting.

I rest my case. This IS a guy who drives a car dealer nuts. Most people would turn down the heat if they're too hot, but this guy not only measures front focus with questionable ruler photos, but he takes a thermometer into his BMW to make sure the temp he sets his climate control is the same reading on the thermometer.example just bought a 2003 330 BMW convertible had trouble with the
heat at first i thought it was just me heat was always on too hot.
brought it in and the dealer who i am friends with showed me a
bulliten from bmw stating that cars of my model produced in a
certain month have a programming error in the climate control
How sad. Everybody give up on this thread and relax. Take some freaking photos or something.

i hope so i sent mine back this evening if my 10d was working i wouldn't be posting to this forum i would be out shooting pictures
i agree with you
it is intresting if you look at all these posts many of them are waisted on useless
display of emotion i just post to see if other people have had this problem and if so
how did they find out and what was canon's response
if every one focused( no pun intended) on that this forum would be more enjoyable

and trying to inject some common sense here. YOU got a bad camera. That does NOT make them all bad. Since you have determined that YOU have a defective camera, you need to deal with it. Trying to scare people away from the camera because of YOUR bad experience is not constructive. Your "ruler" test has been done already... it's not new. In fact, it's gotten VERY old and that's why people are responding negatively to you in some cases. It's clear to me that in SOME cases there could be user error in finding these issues because of some of the responses to my test. Obviously some people believe you can just dial up any particular f/stop on every lens because someone has f/1.8 on their lens. Since you've been into photography for some years, you should know this isn't the case. But the majority of your experience seems to lie in film photography with the recent introduction of digital. It may be photography but it IS different. You'll see flaws in digital that may have been there all along but never was aware of it. With the instant feedback of digital, you see MUCH more. I also have 30 years in photography and I really enjoyed working in a darkroom but I learned things when I switched to digital and saw things I hadn't seen when working with film. And I hope you're not trying to insinuate that I somehow gain from 10D sales or possibly work for Canon as I do not. I simply hate to see people scared away from a camera that I feel is a good value. I'm very sorry that you got a defective camera and I'm happy you sent it back for adjustment. That's a POSITIVE step.
