The outcome of the Official 10D AF test in Korea

Go to last post
Exactly, yet that has not stopped you from denouncing the 10D focus results as horrible and unacceptable. One might thiink you are predisposed to negativity when it comes to the 10D and focusing.

I'm going to assume that it's a focus test that's done in good
light, designed with a very contrasty subject.

Discounting human error in conducting each shot, I'd think the AF
accuracy under such conditions should be less than 1 percent.

Of course, we don't even know what constitutes an "AF error" in
this test.

This should be a case study about how this issue has been completely blown out of proportion. There are those that are so eager to condemn this camera that they allow common sense to be replaced with the truly ridiculous.

DavidP starts out by condeming the camera based on the test results wityout even bothering to understand the testing conditions. In a later post he postulates that if this test were done in good light with a contrasty subject these results are horrible.

Look at Stefan's response. He has already went forward to carry the torch that indeed this test was done in good light and with high contrast subjects.. He goes on to say that "But if it's already at 6.8% under ideal conditions, where will it go to from there? 30%? 50%? More? That's terrible!""

I predict that within two days it will be widely reported that the 10D suffers from a 30 to 50 percent focus failure rate.

This is almost funny.

That is my assumption, too. But then again, it's only that - an

I couldn't agree more. Focusing at a well lit, contrasty target
which does not move with properly functioning equipment needs to
yield a 99% to 100% succes rate. Not less than that. If it doesn't,
the AF system has one or more MAJOR flaws in design. Take away any
of the two (good light, contrast) and move your target (or the
camera) around even slowly and the error rate will skyrocket all on
its own. But if it's already at 6.8% under ideal conditions, where
will it go to from there? 30%? 50%? More? That's terrible!

You seem to have plenty of time and energy to denounce the 10D and this supposed focus issue. Why don't you take the time to understand what the actual test conditions were prior to starting yet another "the 10D focus sucks" thread?
DavidP said:
Assuming that these were actual AF targets (high contrast) shot
under good light, there's just no excuse for a 6.8% error rate in
the AF.

Especially when a flash was used (did they turn off the AF-Assist?).

These aren't "real world shots" we're talking about. Presuambly
they were very controlled tests that an AF system should be able to
handle with ease.
John Fisher said:
....if you actually read the post.

"1. Out of 279 shots taken using 50mm f/1.8, 17 shots failed to
nail the focus point. That translates into 6.8% focus error, which
Canon concluded as an acceptable range."

The 6% has nothing to do with QC on production units, it has to do
with individual pictures take by all of the cameras. This
translates to approximately 2 pictures per 36 shot roll of film
which are not perfectly focused. While this may seem like the end
of the world to some, others are free to observe how silly it seems
to think this is a real world problem.

By the way from the actual statements made (as opposed to made up
stuff by some less alert people), it would seem that this test lead
to the conclusion by the Korean Camera Club that there was no
significant problem concerning the focus capabilities of the EOS
10D.

I'd be happy if 1 out of 100 pics where OOF -

But my hit rate is 1 sharp pic in 12 - on a good day / the rest are FF
When it focuses spot on the results are amazing !!!!!!

My 1st body was enchanged ( was FF at F2.8 )
The second 10D I got was also FF at F2.8

The camera has now been sent into service 3 times

10D and 24~70L went in for Full calibrations ........... each time and have had personal assurance from the service manager each time that it's 100% -

Canon Service has had my camera longer than me .

Unfortunatly this is not good enough ,
I've given the camera and canon heaps of chances to get it right , but i have no
confidence in the camera now ---

As a Wedding Photographer I cant chance using it for a Wedding .

So I will be returning back to my Blad and 35mm Film cameras
  • which gives me spot on focused images.
Thanks to everyone who has posted ideas ect on ways to rectify the way
the 10D focuses .

Zipp

Fun and games always

I'm an engineer. And I try to be objective, and discuss the ISSUES, not personalities.

It's not hard at all to extrapolate the experiences I've had with a 1D to the 10D, especially when so many others have posted about those problems.
GBear said:
I like DavidP and his comments are often valuable. But how
interesting that you would turn for your definitive information on
the 10D to a man, however skilled, who (if I understand correctly)
neither owns nor uses one...

(I have no alternative suggestion; I just literally find this
interesting, and rather typical of this forum - perhaps the people
who actually USE the camera are so fanatically biased, either PRO
or CON - that DavidP is more reliable)>

What do you know about the AF test targets used? The fact that the D100 used as control fared worse than the 10d should tell you something. It is not difficult to device a test that would confuse even the best AF system in the world. For a normal AF test target with good contrast, 6.8% failure WOULD be bad, but we just don't know at what conditions the failures occured in this test. Canon might have been present, but I don't think they DID the test. The failures were probably acceptable at the conditions where they occurred (low light, small target or low contrast target)

I haven’t had a chance to browse through the forum to see if anyone
else already posted the news. But, here’s an update on what
happened at the official testing of AF issue among the Korean SLR
club that began to boycott 10D.

The test was done in the presence of 5 SLR club member, Canon
technical team, and LG reps. The test equipment was one 1Ds, one
Nikon D100 and five 10D. Of the five 10d’s 3 of them had already
gone through service and 2 of them had not. Apparently all five
10Ds tested were presented by SLR club as defective or problematic
even after recalibration [Correct me if I am wrong, my Korean is
very rusty].

Here’s a brief summary of the result
1. Out of 279 shots taken using 50mm f/1.8, 17 shots failed to nail
the focus point. That translates into 6.8% focus error, which
Canon concluded as an acceptable range.
2. There was no correlation b/w focus failure and serial number of
the camera tested. The serial numbers of the 10Ds included
0330-,0530-,0730-.
3. The three recalibrated 10Ds produced much sharper results than
the non-adjusted.
4. The Canon’s position after the test was that there is no
focusing issue with 10Ds in production.
5. SLR club members seemed to agree on this point as well, at east
on an official note.

Here are some other tidbits that came out of this meeting.
1. On average 10% of Korean 10D users went back for service.
According to Canon, this number is much higher than those seen in
any other countries.
2. Of 1D, 1Ds and 10D, 10D, according to Canon, 10D sensor has the

highest AF sensitivity, which doesn’t mean it’s better [I couldn’t
quite understand this point].
3. Firmware 1.0.1 has nothing to do with any AF issues.
4. According to the test, 10D demonstrated higher focusing accuracy
than Nikon D100 [no quantitative test results were given].
5. LG/Canon stated that any focus recalibration after this meeting
would be done using a standard body and lens shipped from Canon,
Japan to avoid any further compatibility issue between different
lenses and bodies.
6. Another surprising outcome was that LG would extend their
warranty service to 2 years from the date the camera goes through
service.

Now, my personal conclusion!
1. There apparently exist some 10D with focusing problem, but they
seem to fall under the manufacturer’s acceptable quality control
error.
2. At least in Korean DSLR user circle, the majority of focusing
issues reported on their site were more psychological than factual.
3. Here’s the last but not the least. We should stop posting or
reading about this AF woes and go out and take pictures. Once
there was a time when this forum was about photography and not
photo gear.

Happy clicking….

I made it quite clear that the the conditions and procedures carried out have to be ASSUMED. And like David said, when such a test is carried out through (or at least in the presence of) reps of Canon, as well as their national distributors, it's fair to assume they set up this test properly. It would make no sense for them to use poor lighting and a low-contrast target. Under this assumption, the error rate they have experienced can only go up in real-world conditions, not down.

But I conceed it's possible they did the test by photographing a black truck in moonlight, so everybody elses AF error rate will be much better than their 6.8%.

In never expect to have a flat tyre when I first time start the engine of my new car. Why? The QC of the car factory can easily detect such thing as a flat tyre. It is their business to make sure the car will roll out of the factory with ease. No flat tyre in a new car is a basic assumption.

Those 10D AF problems presumably have been in those cameras from the day they leaved the Canon factory. Working AF in a new AF camera is a basic assumption. It is their (Canons) business to make sure their cameras work when they leave the factory.

My new 10D is in for AF calibration. My camera had a flat tyre from day one. Canon would not success in the car business.

What I understood from this test - in which many of key engineers from Canon including inventor of USM mechanism based on what I heard - are as follows;

1. they(Canon professionals, Korean amateurs, photography related professionals, etc) tested with 5 bodies both in-doors and out-doors to simulate the field environments.

2. they used many lenses, not only 50mm f1.8.

I think Mr. Solo misunderstood the messages in the BBS. One of the member announced that in this official test, shooting the rulers with 50mm f1.8 had very little thing with actual field test because many bodies including 1D which showed focus variation at ruler test showed very sharp images at real field tests. Maybe this paragraph gives him some translation error.

3. They together shot 279 pictures. Still it is not very clear whether the 6.8% of focus errors are from AF module, user error or circumstances. It may be some issue but nobody(except Canon) is very confident about this. I could read from the board that Canon actually prepared and presented many hidden internal technical information - therefore all of them were forced to sign on non-disclusure agreement - all of them agreed that AF module could never be 100% percent perfect.

Because 10D has smaller CMOS area, Canon should have developed 'more accurate AF sensor' to meet technical AF standard of better cameras, meanins 1D and 1DS. Although AF sensor itself was made more accurate, due to smaller CMOS, it does not mean 10D has better AF functionality - that is what I understood. Do you?

One of the main problem until this test - which is very exceptional one I believe - was that the distributors could never provide satisfacatory services to their customers. They adjusted lenses and bodies without any standard tool from developers which amplified the bad effect. Canon and the distributor admitted this problem and they are now building a new(?) standard of calibration and offered 2 years warranty to customers who purchased 10D before this event to compensate miscalibrated bodies and lenses - in the mean time Canon declared that the AF module of any software is not changed or will not be changed before and after this event.

The above is all based on my personal understanding to help you to see the facts of the test.

I don't think the miss rate of 6.8% is anything to write home about or even get carried away about.

My Fuji 6900z had at least 20% miss rate, probably more, yet I still shot thousands of keepers.
My Sony 707 was not as bad, maybe 15%, once again thousands of keepers.
My 10D not 6.8%, maybe 2-3% and most of those are my fault.
I'm not perfect and either is the camera, or any camera for that matter.

It's difficult to comment on the results of the test without knowing exactly how the test was done. We don't know the test setup used, we don't know how many shots were taken with and how many were taken without a flash.

However, I tend to agree with you that 6.8% failure rate was high if the test was performed under ideal conditions (e.g. similar to the 'standard' test described by Pekka) and 1 DOF (using the stand COC of 0.035mm) was used as the criteria for judging failure. At least my 10D yielded less than 1% failure under these conditions according to my own test.

If it was a real world test then 6.8% was not too bad, but such a test and result won't silent the doubters. I won't do that I were Canon. So, I really don't understand.

One more thing interested me though. The Korean people seem to be quite critical on this issue (the 10% return rate confirmed that), why then do you think that they accept the results? I wonder.
DavidP said:
Canon was involved in this test, were they not? Don't you think
that they'd want to give the 10D every chance possible?

From a few posts, it even sounds like the test were done with a
flash (AF-Assist lamp) and at f/4 and f/5.6

If true, then the 6.8% failure rate really IS horrible.

I have the same query... being so critical on the issue, why would they accept such "apparently unacceptable" resuly? There must be something we don't know.

May be you could help by telling us more on what's been said in the slrclub website. I can't read Korean. :-(
papablue002 said:
Being a native Korean living in LA, I've been following slrclub
forum closely for awhile. Slrclub members were much more vocal than
dpreview members on focusing issues, even went far as to boycott
10D. It seems clear that after the test slrclub members are
satisfied by the outcome. If those hyper-sensitive members are
satisfied by the outcome, then I must conclude that focusing issue
is not a design flaw.
But I can't help wonder why my 10D misses focus once in awhile.
Click to expand...
 
With all the 'engineers' in here.....

Not that it's a HUGE difference, but 17 missed shot out of 79 is 6.09%, not 6.8%.

Also, the 5 10D's were "presented as defective." So, this, again, does not translate to a sample of all 10Ds. Nobody ever denied some 10Ds had problems; if even two of these really were problematic, that skews the sample.

Also, 5 cameras do not a representative sample make!

We also don't know how those 17 bad shots were distributed. All evenly though all 5 cameras??? Doubt it... There could be a chance even one had 13 missed shots, another 2, two 1, one zero! So, one in the batch could have truly been defective -- the others could have been just fine. Hell, 4 could have been fine, with one bad one. Even if the distribution was close to even, we could see one with more problems than the others, say 3/3/3/3/5 or 3/2/3/3/6!

If I went to any electronics store, picked out 5 supposed "bad" units of one type, even risking the chance that one TRULY was bad, 6.09% accuracy in anything it's supposed to do would not be that horrible.

gone through service and 2 of them had not. Apparently all five
10Ds tested were presented by SLR club as defective or problematic
even after recalibration [Correct me if I am wrong, my Korean is
very rusty].

Here’s a brief summary of the result
1. Out of 279 shots taken using 50mm f/1.8, 17 shots failed to nail
the focus point. That translates into 6.8% focus error, which
Canon concluded as an acceptable range.
2. There was no correlation b/w focus failure and serial number of
the camera tested. The serial numbers of the 10Ds included
0330-,0530-,0730-.
3. The three recalibrated 10Ds produced much sharper results than
the non-adjusted.
4. The Canon’s position after the test was that there is no
focusing issue with 10Ds in production.
5. SLR club members seemed to agree on this point as well, at east
on an official note.

Here are some other tidbits that came out of this meeting.
1. On average 10% of Korean 10D users went back for service.
According to Canon, this number is much higher than those seen in
any other countries.
2. Of 1D, 1Ds and 10D, 10D, according to Canon, 10D sensor has the
highest AF sensitivity, which doesn’t mean it’s better [I couldn’t
quite understand this point].
3. Firmware 1.0.1 has nothing to do with any AF issues.
4. According to the test, 10D demonstrated higher focusing accuracy
than Nikon D100 [no quantitative test results were given].
5. LG/Canon stated that any focus recalibration after this meeting
would be done using a standard body and lens shipped from Canon,
Japan to avoid any further compatibility issue between different
lenses and bodies.
6. Another surprising outcome was that LG would extend their
warranty service to 2 years from the date the camera goes through
service.

Now, my personal conclusion!
1. There apparently exist some 10D with focusing problem, but they
seem to fall under the manufacturer’s acceptable quality control
error.
2. At least in Korean DSLR user circle, the majority of focusing
issues reported on their site were more psychological than factual.
3. Here’s the last but not the least. We should stop posting or
reading about this AF woes and go out and take pictures. Once
there was a time when this forum was about photography and not
photo gear.

Happy clicking….
