I've been getting an error 99 code recently. It happens after I've taken several photos. I'll turn it off, wait a few seconds and then try again. I can usually get a few more pix, but then it pops up again. I took the lens to the camera shop thinking that was the problem (it's a quantaray)and they said it works fine. Any idea's what the problem could be?

there are many things about that error. some says is a bad contact between the lens and body. it can be fixed turning the camara off removing the battery and wait 134 seconds. cleaning the contacts can be usefull.

Actually, it can be more than the lens... I had a similar episode that was cleared up by cleaning the flash contacts. Quite possibly it is some sort of contact is dirty.

I have gotten this error with a bad memory card too. I read somewhere, about 3 years ago or I would site it, that the error 99 just means, "hey umm user theres a problem, not quite sure what to tell you it is so umm 99!"

This was with a 300d when I got the error.
A friend of mine also got the error on his 20d when he would use one of my lenses on his camera.

Are you using a battery grip on the camera? I get that sometimes with that, I just unscrew it a bit until the power disconnects and then screw it back in.

Okay, this struck me as really funny :)

Koriley is right its a 'catch all' error code. Some people use a rubber (eraser) to clean the contacts, which can help. I had the same thing, but it was the shutter malfunctioning... and it had to go back :(

I hope its nothing as serious!

Do you experience this with original lenses or with lenses from other manufacturers? I know that older thrid part lenses can have this problem and I've experienced it myself with an older Sigma zoom.
11/09/2006 11:54:38 AM · #9
I was about to mention the sigma problem. Thats the lense that does it on my friends camera..

my d60 started doing that, then stopped being able to fire the flash at the same time the shutter was open...the entire shutter mechanism is failing.

you can clean all of the metal contact points on your lens, camera, battery, etc...as a way of making sure that isn't a problem.

Just looking at the lens is only looking at half the issue. It's the communication between the camera and the lens. As has already been suggested it's most likely the contacts so giving them a good cleaning is a first step.

Also, if the lens is somehow loose on the body then connection could be lost, especially if the lens is fairly heavy and the mount is a bit loose.

Taking the camera body and the lens to the camera shop and showing them the error will also help in determining the exact problem.

This would happen frequently with my XT when I used my 17-40 "L" I would remedy the problem by taking the lens off and putting it back on. It only happened when I used this particular lens on that body. It has never happened on my 5D yet.

I also faced similar problem when I swich between new Compact Flash card with the old one in my 20D.

Do we have a technical guide where we can find the possible solutions for these kind of problem?

unfortunately, when you see the "99" error, it really is a catch-all. The most *common* cause is contact-related, but certainly not the only cause, as evidenced by the previous posts.
The best way to troubleshoot is to carefully note the conditions under which it happens, and see if you can narrow it down to a particular lens, or card, etc.; that way, you have an idea of where the problem is. If the camera does end up needing service, being able to provide this kind of informtion to Canon will greatly increase the probability that they will be able to correctly diagnose and correct it in the shortest possible time.

I may be a little late on this one looking at the dates but, ... once upon a time in a past life, I was an electronic technician specializing in small electronics and test equipment. The fact is that, all contacts corrode by virtue of their ability to conduct electricity. That corrosion tends to become an insulator slowly stomping the flow of the electricty necessary to make the camera work. And, yes, an erasser works for cleaning the corrosion off the contacts. However, a new dollar bill or equivelant works much better. It has just the right roughness to scrape the corrosion off the contact(s) and it doesn't leave damn rubber dust that can get into the sensor area. In either case, whether using a monitory note or an erasor, don't work the contacts over to hard as the scraping wears them out.

It is the camera maker suggesting that you dump Canon and buy Nikon.

Oh the dreaded error 099
My 350D is getting it after about 40K shutter actuations.
Sometimes it hangs, with only a battery removal to reset it, then when the battery is put back in, the shutter closes. If I try and use anything on the back, such as preview pics, ISO, AF, WB adjustments, etc, it locks up showing only the battery life icon with one bar showing on the small LCD , and only a battery out/back in will reset it so it can be used again. The camera will still function for the most part with all the settings as they are, with an occasional lockup and battery out/in to restore it. The grip has been removed, both batteries tried, all the flash cards tried, all the lenses tried, the contacts cleaned on body & lenses, all to no avail.

At least my last 100 shots or so this past week came out OK, shooting blind with no preview/histogram available. Good thing I had it set to ISO200, AWB, Partial metering, Flash exposure compensation at -1EV, RAW and no in-camera contrast, sharpening & saturation boost. At least the exposure compensation, exposure lock & the AF points adjustments still work if needed.

UGH.
Time to send it in...

Update:
I'm not going to send it in after all. I am replacing the shutter assembly myself.
I fix stuff for a living, so why not this? Nothing to lose anyway.

From my experience, error 99 seems to most often indicate a failing shutter. I have had it before and the problem deteriorates until the camera fails and requires a shutter overhaul.

i got error 99 when the contacts on my lens got grubby. i still haven't had that lens fixed, but my others work just fine.
12/07/2007 04:24:47 PM · #20
Just to add to this, a friend of mine has a 300D and was having error 99 with his 70-300 lens. I put it on my 1DMKII and it gave me an error specific to the lens itself. I'm not sure if the 1 series has better self diagnostics for the codes or what but I could take one photo with the lens on mine and it would give me a code 01 or 02 cant remember which is was.

I got 70K clicks (and then it was the shutter button not the shutter that went south) out of my 20D after the 99 error a couple times... as mentioned below I think it is just the Catch All error. For me it was as simple as dropping the battery(ies) and all was fine.

Got this error on the 4th of July while taking pictures of a fireworks show. Only have about 12K shutter actuations on my 40D. Tried removing and replacing the matteries, the lens, tried every lens I own, removing and replacing battery pack, cleaning lens contacts (was obviously not using the flash so I didn't clean that contact). No clue why it did it, took it back where I bought it and they sent it out for repair. Amazing, just when you think you did something right by buying three grand worth of camera and lenses and stupid crap like this won't happen, it happens. Good thing I have my 30D as a backup because I have a wedding tomorrow and would've been screwed otherwise!

I have a Cannon 40 D and it has come up with an "error 99 " message today. I was shooting and then all of a sudden it came on. It will not go away. I changed lenses, cleaned the contacts, changed batteries, took off battery grip. I did all that and still there . Does anyone have any information on this and what I can try differnt , I just hate to send it back to Cannon it will take forever... But from what I have been reading looks like I will need to send that back.

I have a Rebel XTi for +2years and recently I was bothered by the Err99 message. After a lot of exercises I noticed that the problem occurred only with the 28-90 canon lens. I've tried to clean the contacts, both on camera and on lens, and nothing new happened. The problem is not continuous and it seems to me some kinf of problem in the lens itself. So I have two ways to go: by new lens and give CAnon a chance or just switch to another big brand.

on my canon 40D I have tried ...

cleaning the lens contacts
replacing the batteries
removing the battery grip and replacing it
removing the time/date battery to reset the camera
tried 2 other lenses (after cleaning the contacts)
I even tried to put the camera into sensor cleaning mode, but it just flips the mirror back down and gives err99

The camera is about 2.5 years old with less than 7000 shutter acuations
The camera was on a tripod being used for product shots at the time of this happening

I have shoot ...
a comissioned landscape shoot this thursday at sunset
more product shots to be done in a couple of weeks time
a concert on 20th July
white water rafting 24th July
holiday in newquay 9th-13th August
a wedding on 14th August

So I need my camera and cant afford a replacement at the moment.

Any ideas people
thx in advnace
