I guess you can tell us what the percentage is of users reporting this problem?
Nope, what makes you think I can do that? This is not a rumor I have started. Nor did I post I have err99 problems with my 50D. I am only expressing my concerns as a potential 50D buyer. Nothing more, nothing less.
In case you have not noticed, this has happened with every Canon DSLR made. Nikon and other DSLR's get error messages as well, in case you don't know.
Of all the Canon and Nikon gear I have owned and used so far, I haven't had a single err99 issue. You make it sound as if it happens all the time... Where I come from, an error is an error because something isn't working as it is suppose to... Since you seem to be an expert on this matter, maybe you can provide us with some percentages...
Perhaps all the fearmongers and rumor-posters should read up a bit on error messages. Any reason why we should believe this rumor in the first place?
Any reason why we shouldn't...? You just said yourself it happens all the time. Besides that, why should all the 50D owners who are reporting err99's lying about it?
I have to go out now and see how many err99's I can get on my 50D.

not so. most modern electronics today work on high/low not on/off concept. turning off a product requires a path resistance at x ohms or higher not a complete open. same the other way around to go on. if you exceed these values errors occur. corrosion or poor manufacturing technique play havoc with these things especially on close tolerance circuits. insufficient grounding of shielded areas also.
sorry people these things no longer are simple battery to lamp series circuits. the level of sophistication in these things to both operate communicate and use power efficiently is rather daunting and sometimes what sounds like BS may not always be so due to the level of understanding needed to understand how they actually do work ...Show more →
Seems true because my old MarkIII had the same symptons and Canon issued a new firmware to slow it down. I had error 1,6,99 & lens lockup & camera lockup with that camera...

The claim made here, and attibuted to a Canon rep, is that the 50D contacts do not incorporate enough gold, and thus are defective. 50D being a brand new camera, the phenomena which you describe are not an answer for the claimed issue, because, as you rightly point out, they may apply over time, but not instantly. Also the fact that the contacts "do not incorporate enough gold" or whatever, does not in any way make them defective or less conductive. Plain copper would work just fine in the short term. Hence my conclusion that the explanation is nonsense.
Agreed. Some of my older EOS bodies have contacts with no gold--frequent lens changes wore it off--and they work fine.

sorry, dont think that will ever work. Imagin how many users have problems that DONT post on forums. The forum people are only a slight handful.
The same goes for those who don't have problems. These statements that "many" people are having problems with Err99 is not backed up by any data other than a those complaining on forums.

Ohms law would be a good place to start, read up on that and you will begin to understand;
I=VR
Gold and copper have different resistivity as does gold and tin or any other metal. If the program code is written to identify information as resistance values in a minuscule range then the difference in resistivity in the contacts could by all means show errors or cause faulty focus info ect.
Copper Resistivity = 1.7E-6 ohm-cm
Gold= 2.44 e-8 ohm-m
Huge difference if all of your calculations are read on ohms and resistance.
I have no Idea how how the canon programs are written but the theoretics of the problem described make sense from an engineering point of view. ...Show more →

you think so do you? you are not just talking of simple voltage levels you are talking data at various voltage levels. we are talking another level here. hence your conclusion is that you don't really know. i can't tell you how many (pins) contacts i have to change on canon (no relation) plugs for data issues on the B777 due to poor contact and corrosion. but hey what do i know? i just work with this stuff daily.

Well, in your first post, you said There were some reports ...... , then in your second post, you said, ...... that so many 50D users ..... . Can't you decide if it is "some" or "many"?

Well whoopee for you. Perhaps if you read the links I provided, you would see that it is not an isolated problem, and not restricted to Canon cameras. You might also learn that many err99 messages are a result of dirty or poor contacts on the lens, not the camera.

How about because the rumor is alleging the fault is with the camera contacts, and no proof has been offered to back this up. I said the err99 has happened on every Canon DSLR model made, and the links I provided back this up. And, I never said 50D owners are lying about err99's, but perhaps you can show us where some of these owners have proved that the err99 is being caused by the contacts as stated in the rumor?
Got the err99 error once, after about 20 shots on the camera. I pulled the battery and it fixed the problem, and it never came back again.
I returned my 50D five days after buying it, and am now totally glad I did! I'd hate to have a hampered AF due to some scrimping on gold in the contacts.

Thanks for providing me with all this information. I also looked at your posted 50D images, and although it is hard to conclude anything based on web-sized images, they look allright. You obviously seem happy with your new 50D. Well, good for you
Thruth of the matter is that there are many reports (while at first there were only some) of 50D owners reporting err99's. As a customer I really don't care what is causing this (I am not going to defend the "rumor" either). I am concerned about it though. An error is an error, whatever the cause... On top of that there is already a FW update... What is that all about? I think I have a right to be critical... Canon expects me to pay some good (and well earned) money for their products.
Maybe I was lucky never to have experienced err99's with my Nikon and Canon gear. Yes, I guess "whoopee" indeed... But I feel sorry for all those people who have bought a brand new 50D (and paid the grand price for it) and have gotten err99's. It is very disappointing to read about it.
This err99 "issue", some other considerations, and the fact that the official ACR 4.6 release doesn't do a better job at noise conversions than ACR 4.6 beta/RC, is making me cancel my 50D purchase. And nothing you scream at me is going to change my mind about that
BTW I have never seen anyone getting so defensive over a piece of equipment... Relax man, there are more important things in life

I have had err99 on 10D, 20D, and 1DMk2. So what?
Always cleared by removing and re-inserting battery and only once in a blue moon. Big deal.
I have even had errXXX on Mac computers. So what?
Why is it that we are so complacent with things like this. Instead, we should be letting Canon know this is unacceptable. Just imagine telling the bride that you missed the famous kiss because your camera locked up. Canon will not do a thing about this if we all think this type of function is just par for the course.

That is because we all accept these issues and all we have to do is pull out the battery and reset it. Hogwash. Canon is starting to go down the path that the American car manufactures did with releasing low quality product. We need to let Canon know this is not acceptable for a product that costs $1500.

I am with you on this one... I doubt if it will make a difference though. Canon doesn't really care. They have proven that too many times already... Sad but true.
I can get a error every time on my Canon DSLR's by inadvertantly installing a lens when the power switch is on. I still occasionally forget and do this, since the camera goes to sleep after a minute or so, and its easy to overlook.

The xxD are rather cheap cameras and Canon is known for unreliability. I would hope that the pros would be using a tried and true D3 or 1D MK III (one that works properly), or even a 5D perhaps. At least I would not expect anyone to use the new model of the week for serious work before the bugs are known. Even so, failures will occur.

That is not normal IME. At least I've never experienced that issue in thousands of lens changes.
I'm with you EBH, I never power off either my 5D or 30D for a lens change and I've NEVER had any kind of error on either camera, with any lens. Have used the 30D for two years and the 5D for almost 1, no errors, no lock-ups, nothing. I have to disagree about the xxD being cheap cameras, I've been very happy with my 30D and still use it for my long lenses in conjunction with the wide and prime lenses on my 5D.
I agree with Daan B,. why is imagemaster getting so defensive about his camera ? If it worked fine for him, good for him, kudos. But heck, clearly, there are other beta users who can repro the bug consistently. I would get ticked if I had spent $1500 for a new camera. Daan B has a point where he can show his frustration, cos his camera has a fault. Not sure why the Master is getting all worked up....
