I've run into two people who had lock up problems,
one person who had a weird problem where downloading
long exposure images took as long as the images took
to aquire and now I'm hearing the camera has focusing
problems.  Did they release this 10D re-do too soon?

Two doesn't seem statistically significant to make an assumption like that
considering the tens of thousands that have been sold in the last couple of
months. I've had mine for over a month and never experienced a problem. It's
fast, accurate, and a joy to use.

So... keep on trolling.....

I never even heard of such a bug.
Details, even fabricated ones?

A $15 card reader works and will not drain the battery.

All of what I've told you is accurate.  Of course, a handful of such
occurances doesn't mean the camera is flawed,
but with electronic components being as reliable as they are,
things like this can often be traced to design flaws.
So, instead of acting like a little girl who was told she was
ugly, just because you own the camera, why not just indicate
that your camera (even though as the other poster said, the
experience of two people does not = a substantive sample)
works well?  I really do not understand the irrational emotionalism
of owners of Canon and Nikon products.

Make that 4 people Rich...
I bought 2 of the mongrel things. Serial numbers not in the same group so it
couldn't have been an isolated incident. Both locked up when I changed
lenses (yes, genuine Canon lenses) and one died completely. I traded the
dead one (full refund) for a 1D II. The other one I flashed the firmware to
1.05 and fixed the lens change problem only to find more problems when I
used a grip. It too eventually died without warning in the middel of a santa
shoot.

I seems as if the Canon grip has an issue too. Can't use the batteries past
30% discharge or the camera kills itself. This camera is a load of crap. It
forward focused out of the box and still has reliability problems. The
problems with 20Ds might not surface for casual users but press them into
500 shots a day environment and they are duds!

Interesting.  I hadn't seen the focus issues myself, but it was
reported by two people in a yahoo group.  Also, the oddball thing
where the camera takes minutes to aquire the image once the exposure
was done I've seen first hand. The owner of the thing ended up
using his film-based Olympus OM-1 in place of the Canon.

That would be someone not realizing that dark-frame-subtraction noise
reduction was enabled.

So if you take a five minute exposure, the addition of the dark frame

You mean the manual, or the laws of physics? ;-)

Dark frame subtraction is making use of the rather predictable amount
of noise that is generated during exposure. Longer exposure means more
noise, and is dependent on temperature. It also allows to reduce the
visiblity of hot/dead/stuck pixels as well.

Probably the manual.  I'm pretty familiar with dark frames, owing to
doing astrophotography, but to have it as a "default" is probably a
mistake.  But, I'd have to how it's presented in the manual to find
out if the user whom I saw having the problem was just being sloppy
in not reading it.

It's off by default, so the user must have switched Custom Function 02
(1 second or longer, long exposure noise reduction) to on.

Dark frame is turned off by default on the 20D.

That isn't pathetic that is just how it works. It needs two images with the
same exposure one for the image and one to use to remove the noise. If it
was to do a 1/500 of a second frame to remove the noise to speed up the
process it wouldn't have any noise to remove. This is why this function is
turned off by default. It should only be used by those that truly understand
what it is doing and why so that they don't bitch and complain like morons.

It's not something to "fix".  That's how the process works.  It has to
take the same length of time as the initial exposure.

That's not pathetic; that's the definition of dark frame subtraction.
You can turn it off if you want, but if you want it on, there is no
other way to get the proper dark frame to subtract than to take an
exposure of equal length with the shutter closed.

Is that the only way it could be implemented? That's a lot of down
time when shooting a series of 5-minute exposures. Could Canon have
designed this feature like custom white balance, where one reference
dark frame (of 5 minutes) is taken and then subtracted from all of the
subsequent 5-minute exposures?

No, not and have it work properly.

Variables that affect noise are exposure time, ISO, and sensor temperature.
Because of the latter, the dark frame has to be done at the same time as
the exposure, especially with long exposures, where the sensor will get
hotter as you do more exposures in a row.  That will change the noise
pattern.

You always have the option to do that yourself.  You can also break your
shots down into multiple, smaller segments, and generate a blackframe of
the length of each segment, and subtract it from each, and blend the
results together. for even lower noise.  If there are moving trails,
though, you'll get a dropout between exposures.

you obviously have trouble with the dark frame concept.

John Doe - 29 Dec 2004 17:44 GMT
That is what I was wondering because then a say 30 second exposure would be
a 60 second one. 30 Seconds for the image and another 30 seconds for the
frame that the camera uses to remove the long exposure noise.

If you're doing 500 shots a day, you need to be using professional

This is what I mean by operator error. I had a friend at work who owned a
B-grade sports coupe and took it motocross racing on weekends. He complained
about his car having reliability problems with steering and suspension!!
Now, the 20D is not a B-grade camera (I own one, so ofcourse I dont feel
that way), but it is not a full pro body. It can be used for professional
purposes, but in a 500/day shooting situation, a 20D should not be the main
body. I would be surprised if any sub $2000 DSLR body would not exhibit some
type of problem over a period of time where it was taking 500 shots per day.
Some of the issues might even be battery! Some real wackos out there, I tell
ya.

I have yet to see a 20D, but I've had a 10D since shortly after they
came out. It's a great camera but I certainly wouldn't expect it to do
500 shots per day.

Why?  I had several days this summer, and 2 days in the spring, where I shot
600-700 pictures with my Olympus C-2100UZ.  Granted I did go through at least
one battery change.  For snap happy amateurs, I don't see 500 shots/day as
being unreasonable.  I am looking at DSLRs right now, and I would expect any of
them to be able to handle 500 shots/day.

FYI  the problems I have with 20D (other than focus issues) didn't exist in
the 10D and none of them exist in the 1D. I've seen my rivals shoot 600 and
700 shots a day with Nikon coolpix consumer cameras. I used to do it on film
with Canon 3000s. No... Your assesment of the likelyhood of reliability for
6 weeks work a year is off the mark. Randall will love this... My SD9 Sigma
shot this assignment last year and was the backup for the 20D this year.
Guess which camera did the last 2 weeks work and never faltered? Come on

How many SDx cameras have sold, compared to 10Ds an 20Ds?  You're going

I have bought one, SD9 I bought 2, 20Ds and I bought one, 10D previously.
For me that makes 3 problem cameras from the same maker compared to none
from Sigma.
Hey... I know, I just got a fluke in the Sigma and was downright unlucky
with the Canon's, right?

If Canon would just tell me they are on the case I might feel better but all
they say is bring the camera in and we'll take two weeks to look at it.

I use this camera for 400-600 shots at any given time, and never a battery
problem, forward or backfocus or any other "reliability" problem.  The only
one I've had, related to the camera and after the update on firmware, is the
gawdawful flash metering wit EX series flashes.  And that stupid AA battery
holder with the grip, that now is reposing in a drawer, soon to be
forgotten.

Don't forget that the most vocal crier of "foul" against Canon's 20D was
taking seventeen trillion shots in high Aussie heat, *using the built in
flash*! And some of the time with the above battery grip that certainly

If you assume 1% flawed cameras, your chance to get 2 bad
ones is 1:10.000.  People have been known to win the lottery
with much worse chances.

How do you measure 30% discharge?
Display?  Amperage counter?  Images taken?  Volt meter?
Voltage under load?  Time to load the battery afterwards?

Anyway, I cannot duplicate your grip problems.

that you were goiong to sell it on Ebay, but I haven't yet seen a reply

Accuracy does not make truth.
For all we know you have run into 2 people with lock
up problems and 20.000 20D owners without these problems.

Care to answer the questions?

I imagined there was a computer inside.  I must have been mistaken,
it's all hardwired and there's no firmware which might have simply
normal bugs, so it must be a design flaw.

So 2 nebulous bug reports make a design flaw, yet many 'no

How do you rule out that a few bad cameras slip through QA?

Not sure where you've been during all the ruckus Wolfgang but it couldn't
have been lurking on where a lot of early owners reported all the problems

the cameras with version 1.04 which Canon rushed out a few weeks after the
camera was released. When I took mine in to have the thing reset, I just
happened to notice the rows and rows of what looked like 20Ds in the
workshop.

This is the camera the OP found 2 reports of malfunction over. It is quite a
trick to actually come across 2 people with 20D cameras this early in their
life. For both to have reported problems like I have, some 10,000 miles away
is a rare coincidence indeed.

As for your query as to how I arrived at 30% battery capacity... The charger
Canon provide has little winking lights to indicate battery life in thirds
as it is charged. 2 winks and it's 1/3rd! Each time the camera malfunctioned
with the grip, the batteries were at 30% charge. Since then I have done away
with the grip and used just the single battery without any lockups. Does
this give you a clue as to what might be the problem?

All the problems? AFAIK there was a lock-up issue which was fixed by a
firmware update.
Other issues were related to unspecified brand lenses and dirty lens
contacts, possibly a few failing CF cards, and don't forget
inexperienced user error.

The battery grip is something I distrusted from the beginning, and has
been found to cause at least some if not most of the reported issues.
Lose the grip and problems are usually solved (which is of course not
a real solution, it should work as sold).

Yes, it is a very popular camera, so even a small percentage of issues
will amount to a significant quantity. Of course the cameras may have
been there for other reasons than you assume (e.g. firmware upgrade,
sensor cleaning, checking for often (unjustly) claimed focus
inaccuracy).

Probably not yet looking for a DSLR, but I think I did quite
extensive research, especially on the 20D --- after all, a DSLR
is rather expensive --- and saw nothing which said the camera was
a bad product.  I have not yet had any reasons to revise my
opinion.  The camera is not perfect, obviously, but so far I
only hit minor things.

> There were also a fair few who upgraded their firmware and killed

Actually, the firmware in 1.0.4 was not flawed.  It's exactly
the same firmware as in 1.0.5.  (Which is why I don't believe it
was rushed.)

The firmware loading program of 1.0.4 was not working correctly in
some cases, causing a lot of problems --- which Canon acknowledged
and apologized for.

As to "upgrades a few weeks after the camera was released":
you are using Outlook Express as a news reader, aren't you?  I
can point you to bugs unfixed for years and critical upgrades
mere days after releasing the software.  Are you measuring by a
different yard stick there?

Try going to your workshop and ask how many they sold and how
many ever came back with problems, including a broken 1.0.4
upgrade.

> This is the camera the OP found 2 reports of malfunction over. It is quite a

Why?  Do you believe only a handful of units were ever sold?
I was under the impression it was a very well selling camera.

Only if distance is a variable in the error reported.
Otherwise the locality is not relevant.

Uh --- are you talking about the Canon Battery Charger CB-5L,
which at least came with my 20D?

If so,  you are mistaken on two counts:
- 1 blip is 0-50% (not 0-30%),
- 2 blips is 50+%,
- 3 blips is ~75+%,
- continous is full.

And since this is a Lithium-Ion accumulator, it'll charge
rather quickly to ca. 70% and trickle-charge to full.

Just for kicks I inserted a BP-511A, fully charged 2 days ago,
into the CB-5L:
1 blip, 1 blip, 1 blip, 2 blips, 3 blips, continous.

This has been my observation every time: it'll always start at
1 blip ... but the time spent in 1 and 2 blip mode depends on
how low the battery was run.

Thus I believe your method may badly underestimate the battery
charge left --- you'd probably have to measure the time to load
the battery fully or at least to 3 blips for a usable estimate.

Anyway, the battery works well in my grip.

Assuming the battery grip is not completely broken by design
(mine works), and that your 30% may be wrong (I'll treat it as
'it works in the beginning, but later it stops') it must be an
error either peculiar to your grip or to some grips.  To my mind
the following ideas come:
   - a hairline crack +
       - lower battery voltage.  The Li-Ion-graphite discharge
         curve shows only a drop in the last 20%, so the battery'd
         probably be nearly empty at that time.
       - Heat.  Intensive use of the camera (especially in
         outside heat and/or lots of internal flash) will heat
         up the camera and will spill over into parts of the
         grip as well, causing a crack to disrupt contact enough.
   - cold solder joint --- maybe a QA problem or shock or
     vibration induced (e.g. during transport to your dealer).
     Maybe heat or vibration will cause it to fail temporarily,
     maybe it 'just' increases internal resistance too much for
     a not very full or nearly spent battery.
   - corroded or marginal contacts, either at the battery-grip
     or at the grip-camera interface, causing too much resistance
     for some battery voltages.  May also become worse with heat.
     Have you tried the other battery bay in the grip?
   - marginal contact grip-battery due to size and form being tolerances.
   - marginal contact grip-battery due to dirt (though I
     don't think that'd be the case with your grip)
   - marginal contact grip-battery due to marginal fastening
     to camera body (not screwed fast tightly enough)

On your assessment of the battery measurement, my batteries were at 50% when
the camera failed. I grant their must be something wrong in the grip's
circuitry because without it, I can get the whole battery life without
problems.

I agree also that many of the problems I had may have been environmental. I
used the internal flash after I discharged the external flash batteries and
didn't have fresh ones in my pocket. I was so pleased with the results I
just kept using it. After the failure I looked up the manual and discovered
these cameras are unsuitable for use in some parts of Australia (where I am)
due to the 40C maximum operating environment. It often gets over that here
and on one of the days it gave trouble, it did.

I also think that when this camera is working, it has no equal in the same
class. My issue with many of the disciples of EOS is the way in which you
all defend the indefensible. It is just not good enough to sell a product
for the cost of this camera with faults in it. It is even worse to sell a
product like this camera into a country where daytime temperatures often
exceed the operating environment of the camera... And Canon are not alone
here. The 1D II has a 5C higher operating environment. The 1D I bought when
one of the 20Ds died has given no trouble. It also cost 3 times as much!

So in response to the OP's questions... Yes, I believer the 20D is a flawed
camera. It might be good in Europe but it certainly is not a desert dwellers
camera.

The Australian market is so tiny, its not worth for Canon to worry about the
oddball case of someone in Alice Springs shootin' 500 shots a day of the sun

I am not bashing Oz (just kidding somewhat) - I lived there most of my life
(been livin' in the US for the past 5 years), but what you speak of is a
tiny fraction of users. Not only is it hot where you are shooting, but its
probably very humid. Pretty tough for any electronic device to be used
heavily in that type of env. BTW, as you know much of the "habitted" parts
of Oz have nice mild weather (Melbourne eg). If you hate the 20D so much,
get something else, but dont get all flustered about it. Let the rest of the
users enjoy their (working) cameras. They probably send the lemons to Oz
anyway.

Circuity or contacts.  I'd bet 3:1 on contact troubles over
circuitry troubles --- there's not that much circuitry inside!

There is no product without faults, be the product software,
cameras, cars or butter knifes.  All that matters is if, how much
and how often these faults impede you and/or others.

Well, there _may_ be a relationship between tolerance and price.

When you walk into a camera store in Australia and the temperature is 43C...
Supposedly the camera can't be demonstrated due to the temperature exceeding
the camera's operating environment. Silly as it sounds this is a real
scenario in Summer and in a lot of Australia. So how can you claim it a
limitation when the camera is unusable in the country it is sold in?

If Canon were in the least ethical, they would either not sell a product
unsuitable for a countries environment or make it work in that environment
in the first place. Even Volvo send their pre production cars to Australia
for testing before they go into production... Why not a camera?

Not all the world is Australia.  I usually see that tunnel vision
just from USAnians, though.  But there are other countries ---
lots of them --- where the 20D is sold, too, which do very seldom
'enjoy' 35°C.  And I venture guess, the 20D is selling more there
than in Australia.

Additionally, you have heard of air-conditioned studios?
The camera would be very usable there, wouldn't it?  So it's not
"unusable" after all.  Oh, do the coastal regions of Australia
--- you know, where most of the population resides --- do they
get as hot as often as well?

How comes you don't castigate the shop for not telling you the
limitation they *must* have known about?

> If Canon were in the least ethical, they would either not sell a product

So you'd really demand that Canon violate free trade agreements
and somehow force your local camera shops not to import and sell
the cameras the shops think their customers want?

Unlike air-conditioned studios, the number of air-conditioned
roads is severely limited, even in Australia ...

All your arguments considered, Wolfgang, How would you feel if you shelled
out $7k AUD for a project and all the cameras died from environmental
fatigue 10 day into a 6 week shoot?

How would you feel also, if your plans to shoot a very rare Croc hunting
expedition in the far north suddenly needed an extra $5k AUD of cameras
because the "pro" 1D, II decided the heat was too much also?

Free Trade agreement or not, any manufacturer selling goods in Australia has
to abide by the Trade Practices Act. Part of it relates to suitability for
purpose. If the cameras (20D and 1D, II) are not suitable for Professional
use, the importer is in breach of the act. How too, will the
Photojournalists covering the disasters of the world in arid and tropical
regions react to their cameras shutting down from fatigue? Probably the same
way I have... Get rid of them and go back to more reliable gear.

Your arguments are flawed.
I agree the 20D is a nice camera and that Australia's heat is limited to
maybe 4 months of the year. Can I come and live at your place during those
months? They are the most productive for me.

Well, I'd be pretty, aeh, unhappy, about that.  Now, if I bought
the camera in Australia, especially in a place where the same heat
is (sand or salt or water being another problem, but one _ought_
to know about them), I'd be really non-plussed with the shop for
not telling me.

Assuming, of course, that is a stated limitation of said camera.

However, if I took said camera to such a place (having bought it
in, say, Europe --- especially if I *didn't* ask my dealer "Will it
work well in central, hot, dry, dusty, desert Australia?" before)
and stumbled over limitations clearly stated in TFM, my fault
it is.

How'd you feel when you go visit McMurdo station and your camera
decided that it is waaay to cold there and you'd need another one?
_I_'d consider a conventional body as back-up ...

Ah, so all camera shops belong to Canon (manufacturing arm) in Australia?
I'd thought it was a more, ah, free country.

What is and what is not "Professional use" and if they are suitable
is something for the courts to decide.  I still stand on my point:
They are perfectly suitable for studio work.  If they are suitable
for professional studio work anywhere in the world is another
question, obviously.

Photojournalists (daily newspapers) know their equipment ---
they have to --- and know their environments, at least if they
do their job.  Thus they'll have suitable cameras, and know the
limitations and 'flaws' and flaws of their gear.  They also have
colleagues to ask for advice.

Photojournalists (large print or magazines) probably still use
slides (and medium format cameras) for the neccessary resolution.

So are yours.

You may find the travel costs prohibitive, and of course, shooting
pictures in Australia is right out, then.  Oh, your landlord does
not let you dwell for free (nor does mine), so some compensation
will be needed.  (No, my employer will probably not be happy with
me being stuck in Australia, not with all these drop bears and
deadly everything around.  And I don't, ah, _like_ that much heat.)

Apart from that ... well, bring plenty _warm_ clothes, a
storm-proof umbrella and/or tarpaulin and sou'wester, sand for
the pavement and warm shoes.

That's because the 20D has an option to take a black frame after
exposures a second or longer in length, to subtract the noise.

My 10D backfocuses.  My 20D does not backfocus or frontfocus in any

You know, its amazing how many people think this is a problem. Solution is
simple, go to Cfn and turn off noise reduction. Like anything else (whether
it be computer SW, cars, stereo equipment, cell phones etc etc) most of the
problems people encounter are operator error. In some of those cases people
abuse their equipment and expect it to work. I would just ignore these
screwballs (hehe). I have been using Canon equipment for years (so have many
of my friends) - never had a single problem. This would explain why Canon is
the most successful DSLR/SLR maker.

My 20D has no problem, same for my friend. Your gonna tell me that both of
us are lucky , right ?
