I had one lockup from using this camera. I really didn't know it was a
bathroom window I was shooting through but anyway I made bail just fine.

I don't know.

There was a firmware issue and the revised firmware did correct the problem
in some cases.

Probably not. I am still experiencing lockups, have the latest firmware,
and never use a battery grip. My problem seems to be related to one lens (a
100-400 IS). Other users have also reported lockups when using IS lenses.
However, it seems to be a rather rare problem.

My 20Ds all locked up on changing the lens but upgrading the firmware
fixed the problem... Until I bought some 580 EX Speedlights! One after
the other, they locked up with the speedlights set to ETTL and the
camera set to 1/250th sync on Av mode. Canon have no answer, there are
no further firmware upgrades and the problem is very specific.
Thankfully it doesn't happen with my 1d Mk II.

This really is **** poor stuff from a company confessing to want market
share at any cost. I personally am seriously evaluating dumping my
entire Canon camera collection and buying Nikon or Olympus.

The deception Canon pulled in claiming the 20D had superior low light
performance when all they did was include a really poor de noising
routine to ISO 200 and higher pictures is pretty pathetic. Use high ISO
at the risk of lost detail.

I speak from Professional use. There is no reason to believe a private
user could not accept an occasional lockup and the detail loss at high
ISO is really only noticeable with very big poster prints. This makes up
a lot of my business so I am proportionally more dissatisfied than most.

I have an October 2004 20D, and it has only locked up on me one
afternoon during the use of one particular battery; an old and very-used
battery. On no other days and on no other uses of that battery or any
other battery has it locked up. I am up to folder 252 canon, which
means I have taken 15,200 images.

You keep saying this, but I have yet to see any evidence of it. The
noise in my 20D RAW data looks like real noise to me, and when I use
something that reduces noise on the images, detail drops away. Detail
that was *there*, mixed with noise.

The real test would be to take the same shot with two cameras, with a
sharp t-mount lens, both set to ISO 1600, and both set to use the same
aperture and shutter speed, and see how the detail compares.

I've just received a letter from Canon, they have replaced the pin assembly
and the cf slot at no charge. There appeared no physical damage and
certainly no bent pins. I was having sporadic lockups and CF read errors,
usually only whilst changing CF cards during long sessions. If I left the
camera off for 10 miutes or so, the card would read ok.

I'll pick up the camera today. This weekend will be spent trying to repeat
the problem. If all goes well, I'll be singing this camera's praises
following 6 months of use. If not, I'll be posting a $#1+ - bucket.

Hi, The lockup problem was caused in some cases by using Lexar 80x cf cards,
Lexar are changing all cards

The Lexar problem had nothing to do with lock up. It was about lost
images.

Here is my scenario:

1. 20D with 17-85 IS USM
2. Sandisk 1gig Ultra II
3. Shooting in continuous mode
4. Shooting in AI SERVO mode
5. Stopping inbetween to rezoom (camera downloading to CF card)
6. ERR99 when I try to continue shots

Have had the camera since April and no problems at all except for this one
situation. 99% of the time I shot in one shot focus and non-continuous.

My speculation is that there is some issue in regards to trying to read and
write at the same time as well as communicate to the lens during ai servo
mode. More like processing than any particular hardware issue. I know that I
have read many postings about CF cards, IS, pins on the lens, firmware
etc....and believe it to be more in regards to how the camera itself can
multi task and handle complex situations. The power users in the group may
experience this more (not that the casual user wont). If anyone wants to
help me with my thoughts by testing in the above way and see if it happens
more so than not, I'd be interested to hear about the results. If more folks
say that it just happens doing simple point and shoot, then I declare I
would be stumped.

Ed,
I had the same problem with my 20d and the 70-300mm lens.
I would shoot about 8 to 10 photos and the camera would lock up and I would get
the ERR99 message. This only occurred with the 70-300mm lens.
I sent the lens in for service and Cannon said they replaced the IS lens unit.
The lens and camera now work fine.
