I Will Never Buy CANON Products Again

People should be aware that anything electronic is subject to Electrostatic Discharge damage. And it is an imperfect world.
Good luck

I do sympathise with you, actualy I had my heart set on a 20-35
f2.8L that was going reasonably cheap on Ebay but then I read a
Photozone review that said great lens but keep in mind youd be
lucky to have it repaired AT ANY PRICE if something went wrong due
to the age of its parts! (89 model) Opened my eyes.

Opened your eyes to what?

To the fact that even expensive lenses, not just bodies, have a relatively short used by date due to the not worth/able to repair factor. I'm still suprised though that an EF L lense would possibly not be repairable at all.

Back in 1990 I bought an EOS 630 with the 35-70mm kit lens, and have used it ever since. After a lot of arguing and pleading my wife bought me a 20D and 17-85 for my birthday.

The day my 20D arrived I pulled out my old EOS 630 to compare, and decided to put the 35-70mm on it to see what it was like.

Anyway, the zoom was really stiff and would stick at about 60mm on the way to 70mm, and the front lens assembly flopped in and out of its own accord. Previously it had worked fine. What the...?

7 months later, curiosity got the better of me, and I disassembled the 35-70 to see what the problem was. What I discovered was you can't disassemble that lens without breaking it, seriously the thing is (was) glued and soldered together. So, there were some contact pins that rest on an inner part of the lens assembly, and appear to send distance info back - probably to the flash. These longish pins had caught on the corresponding printed circuit board on the lens barrel and were all bent out of shape.

I never did find out what the problem was with the floppy front lens assembly, but there was some other damage caused by my trying to force the lens to 70mm, so it must have been that.

So I got 16 years use out of a $300 lens - call it 35 cents a week. That sounds like pretty good value for money to me.

I did manage to test it against my 17-85mm, and it was close optically, but just a little bit off in resolution. The colour was little bit more accurate though.

Apart from an AE-1 Program that used to die regularly at great cost to the owner, and a EF 50mm f1.8 that front focussed severely straight out of the box I have nothing but praise for the reliability of Canon equipment.

There are regular posts on here regarding recalibration issues, but rarely ones regarding breakdown or repair.

If the OP has an issue with his 10D then I feel for him. He must be severely unlucky, or something.

Resolution??

Let's review the meaning of "Resolution":

Resolution

The number of pixels per inch in an image, or the number of dots per inch used by an output device.

Do you really know what you are complaining about?

I've switched to Nikon. Their cameras never break, and their warrantees are lifetime ... which of course costs them nothing, since nothing ever goes wrong with their cameras.

Why hasn't everyone on this forum made the switch yet?

You're right, I agree 100%. I would never buy a product from a
company that didn't have an absolutely perfect 0% failure rate.
And as far as warranties go, they should all last forever. And, if
a piece of gear ever does fail, which of course it wouldn't, it
should be fixed free, for life, and I should get some cash in the
deal, too.

When not in use, I keep my 20D (sans batteries, of course) in a plastic bag in the freezer. Canon told me it will pretty much keep forever that way.

What sort of maintenance would've prevented a fault in the CMOS
chip as mentioned by the OP?
Click to expand...
That CMOS chip and other electronique parts have a tendancy to
oxydate.

When not in use you should:
  • Discharge totally your battery and store it empty. Don't leave it
in the camera.
  • Keep your camera in a dry rather cool place. Some companies sell
cases for you to keep your camera at a constant humidity rate.

Anyone who's had the foam seals on a mid 70s SLR knows that time alone is rough on a camera. I had the deteriorated gooey foam on mine replaced with felt some 10 years ago and it is now fine. It was obviously out of warranty and I personally paid for it even though all of them manufactured in the same time suffered the same fate. Such is life.

Hi Steve, as for Resolution, I define it as the ability to resolve adjacent line pairs. A lot of physics texts books do the same, so who am I to judge? Sometimes I judge it as the ability to define a sharp edge, which is for my purposes pretty much the same thing.

I wasn't complaining, I was making an observation based on my empirical test results.

What I think is interesting is that a 16 year old consumer lens pretty much matches a new consumer lens. There was very little difference able to be seen.

I know you didn't mean to fully discharge it, but with Li-Ion batteries it can ruin the battery if it's dead when you put it into storage (just dead, not fully discharged).

The reason for that is that the Li-Ion battery will lose a small amount of its charge when it's just sitting there. If you kill the battery to 5% of its capacity (by using it until it's dead) and then put it into storage, it'll discharge and short itself after just a month or two. Charging it to 40% gives you about 6-7 months.

I'm not talking about the permanent capcity loss, by the way. That's a separate matter.

I guess the point is moot anyway, since he wasn't really asking about battery maintenance.
crouvrais said:
Sorry I expressed myself incorrectly, I didn't mean by total
discharge taking the cell to 0V.
Even NICAD and NiMH shouldn't be completly discharged but taken
down to 1v per cell. Discharging to 0V could lead to cell reversal

Total discharge in my mind, was taking to the cell to it's lowest
operational voltage, not to 0V. I should have been more precis, my
expression was incorrect/inappropriate.

Thanks for raising this point.

By the way, I don't know for Canon but for other batteries, you are
sometimes required to charge them once a year and discharge them.

YES WE WOULD. I have a mid 70s SLR where the foam went bad
and I get it repaired on my dime and did not once complain. I also
have a EOS A2/EOS 5 where the command dial broke (ALL of
them have this command dial problem and I'll bet 90% of them
have broken) and I got it repaired as well. I paid for it and have
made no complaints about it. The fact that it broke after warranty
is just the way life works. Canon guaranteed it for a year and it
exceeded their guarantee. End of story. I'm still a Canon customer.
 
I just can't tolerate the ever increasing attitude of our time that every fricken' expectation must be satisfied despite a complete lack of objectivity and common sense. And heaven forbid Suzie Selfish doesn't get her way! She then calls the local, often portly and gregarious, consumer protection news guy who strong arms big bad corporation into giving in due to the threat of bad press. ;) I just don't get it. The pendulum has now swung from the ridiculous to the sublime.

BTW, my reply was actually kind by my sociopathic standards. :)

There's a difference between 20 years and 1.5 years. Everyone knows foam degrades with time. That's normal wear and tear. Having a sensor fail is not normal wear and tear. It would be almost impossible for a user to destroy a sensor without leaving a mark on the camera. If the poster's story is true, Canon would know that the sensor was faulty. I don't know how Australia works, but in California he could have a chance at legally forcing Canon to pay for the repair. Even when things are out of warranty, if it can be shown that they failed due to a defect rather than wear and tear or customer abuse, then sometimes the manufacturer can be forced to cover the repair anyway.

I think this all goes to the fact that basing warrantees on the
passage of time rather than the actual usage of the product is
pretty lame. Unless Canon truly believes that the sensor on a 30D
is likely to fail after 12 months in a dark closet, why does the
warranty expire after a year? To save money, which I think was the
original poster's point.
Click to expand...
So, what yardstick would you use for warranty coverage? Time? Actuations? Lunar Cycles? (just kidding).

But seriously, what would you consider fair and practical?

Most people who buy a camera USE it, they don't put it in a closet unused for a year, so that's not a fair comparison.
