[Lightstalkers] Canon 20D lockup http://www.lightstalkers.org/canon-20d-lockup An entire Lightstalkers thread via RSS/XML. en-us Canon 20D lockup Hi. One of my 20D is out of commission. It gives me "Error CF" message and does not fire. It fires when I take the card out. I used several different cards and lenses on them but same results. I have another 20D, and all the cards and lenses I tested with works fine on the other body. I tried to format the card, but when I do that, I get "Error 99." I tried to reload the firmware (I have 1.1), the camera doesn't even recognize the card. I wonder if anyone has suggestions... I am in Congo... so I cannot fedex it to Canon to get it repaired..... My thanks in advance, Jiro Wed, 12 Mar 2008 12:53:45 +0000 http://www.lightstalkers.org/canon-20d-lockup Re: Canon 20D lockup Hi Jiro: I remember reading that what you have experienced is not all that rare. Has to do with turning the camera off to switch lenses or something like that & then when you power back up -- you experience the lock-up. A few folks said that you might want to take the battery out & then replace it again (something with electrical contacts? discharge? -- don't know, but...) I went to find the link I'd read -- think it might have been this one: http:&#47;&#47;photography-on-the.net&#47;forum&#47;showthread.php?t=43350 Hope this helps you to sort it out, D Thu, 21 Apr 2005 04:49:53 +0000 http://www.lightstalkers.org/canon-20d-lockup#2762 Re: Canon 20D lockup Yeah Jiro: I looked around some more. Two things. Take out your battery & replace it. For starters. It's a known glitch that Canon has tried to resolve. to that end, there's been a few firmware updates since your 1.1 was released. Get the latest one online? Thu, 21 Apr 2005 05:21:23 +0000 http://www.lightstalkers.org/canon-20d-lockup#2763 Re: Canon 20D lockup Oh man Jiro, Not you too... I have had both of my 20D's go out of commission in the four months that I have owned them.... Maybe we should write a joint letter to those folks. Hope all is well there (besides the camera trouble that is)...

I'm not a Canon shooter but I have had the same problem with a couple of my Nikon Ds. It just plain SUCKS!! Good luck.

Thu, 21 Apr 2005 13:17:21 +0000 http://www.lightstalkers.org/canon-20d-lockup#2771 Re: Canon 20D lockup I am distraught to hear these 20D stories. I have one as well, and it has not acted hinky in the 4-odd months I have owned it (just watch, now that I have said something, it will spontaneously combust or something) Is there a list of errors posted somewhere? I looked on Canon's site to see what "Error 99" meant but don't seem to see one.

No, no. I did not pour that precious soy sauce, Craig... in fact my shippment including my precious soy hasn't arrived yet (still somewhere between New York and here). Scott, yeah, man! We do need to get all the photogs together and write to Canon!!!! I was hoping for a miracle cure... but doesn't seem to be any... I am coming back to US briefly in June, so hopefully I can send them in for repair to CPS (it's still under warranty) before I head back here. I am going into the woods (probably jungle is more proper term) tomorrow for a week for a story on refugees. Hopefully I won't see any blinking massage. I am taking my Leica just in case (hope I remember how to put films in it). Jiro Sun, 24 Apr 2005 09:03:39 +0000 http://www.lightstalkers.org/canon-20d-lockup#2813 Re: Canon 20D lockup Hey Jiro, how you doing? You probably won't see this post until after you return from your week in the jungle, where I guess your Leica might have performed better than the ailing 20D... How is that Leica these days? I miss it, man... Sorry to hear about the digi lockup... the firmware updates that Canon released last year seemed to have solved the problem, so it's puzzling that you're facing these difficulties. Did you also try removing the internal backup battery found in the body itself (not the regular lithium ion battery that resides in the grip and powers the main operations of the camera, but the button-sized CR2016 battery that retains the camera's parameter settings)? Not sure it would help, but you could try that... Alternatively, you could try updating to firmware version 2.0 but be sure to follow the directions posted on http:&#47;&#47;web.canon.jp&#47;Imaging&#47;eos20d&#47;eos20d_firmware-e.html closely (e.g., remove lens from body first, then remove main battery from camera for at least two seconds after firmware upgrade). If your camera refuses to recognise the cf though, even with the lens off, it could be a job for Canon servicing... Good luck buddy, Jonathan Tue, 26 Apr 2005 22:31:34 +0000 http://www.lightstalkers.org/canon-20d-lockup#2861 Re: Canon 20D lockup <p>Anyone have any idea how Jiro or Scott Eells went with this fault and if repaired, has it repeated?&nbsp; <br/> <br/> I'm interested in the solution to this specific problem and seek assistance from anyone who had it resolved.&nbsp;That is, seemly random cf err&nbsp;&nbsp;that renders the camera useless, even when religiously following the manual and when&nbsp;fresh CF cards are inserted with battery drop/reformat attempt etc.&nbsp;&nbsp;<br/> <br/> Canon have had&nbsp;my 20D&nbsp;on 4 occasions totalling &gt;2 months over the last 6 and replaced 1 CF unit in May. They have my camera now.&nbsp; The latest quotation is for a replacement CF unit and digital board.&nbsp; (Yeah, they sent me a quote for a warranty rework after I paid for a sensor clean.)&nbsp; This is probably unrelated to the dirty lens/firmware Err99&nbsp;issue and the Lexar CF&nbsp;matters.&nbsp; I have noticed an increasing number of users with identical problems.&nbsp;It is not card brand related but appears to only effect &gt;1GB high speed cards.<br/> <br/> For those reporting this hardware fault have Canon indeed repaired it or should I be briefing my lawyer?&nbsp; Apart from the time delays and blood pressure effects, they have failed to rectify supply of faulty equipment and blamed me for the fault ( On the 3rd attendance, the report claimed &quot;tested OK, then a capitalised NB:&nbsp; PLEASE FORMAT CF CARDS ONLY WITH THE CAMERA.- I had never done otherwise and had told them so on every occasion.)<br/> <br/> I know my camera is a dog, but I'm getting an impression the 20D hardware may&nbsp;have a high failure rate.&nbsp;Great camera when it works but maybe I should be cutting losses and either going Nikon or negotiating an upgrade.<br/> <br/> Dave&nbsp;&nbsp; <br/> <br/> </p> Mon, 12 Sep 2005 03:16:42 +0000 http://www.lightstalkers.org/canon-20d-lockup#7534 Re: Canon 20D lockup Dave,<br/> <br/> When I sent my camera to CPS in New Jersey, they just updated the firmware and sent it back... of course... same problem... (died on me when angry folks are throwing chunks of concrete at me in Kinshasa)... So I gave my camera to a nice agent with Redux when I saw her in Perpignan, and it is on its way back to Canon.... so as you can see, I haven't be able to use 20D for over 6 months... thank god that the other 20D I have is hanging in...&nbsp;<br/> <br/> Jiro Mon, 12 Sep 2005 03:25:40 +0000 http://www.lightstalkers.org/canon-20d-lockup#7535 Re: Canon 20D lockup My pre-ordered Canon 20D and vert grip (both very low serial numbers) started giving me trouble after a couple of months. I called Canon, they said a firmware upgrade should solve the problem (NOV 2004.) It did, briefly.<br/> <br/> I brought it in to Jamesburg (I live right up the road) in March 2005, explaining the same battery-flash lockup problem was going on. They checked it out, upgraded the firmware again and sent me on my merry way.<br/> <br/> I saw the Press release about the issue with the vertical grip (released April 2005) in mid-May, and brought the vertical grip in for repair. They wanted to keep the camera as well, but I had assignments that weekend. So they 'fixed' the vertical grip and it acted up on the very first shoot after the repair.<br/> <br/> I shot without the grip when possible, but that wasn't really a fix.<br/> <br/> So, I brought the 20D and grip to Canon, June 12th, managed to get it to Error out in three tries at CPS, they ran a diagnostic and determined that there was also an issue with the camera, and that's why the vert grip fix was ineffective. They told me it would be 7-10 days to get it taken care of...which was great, considering I was leaving for a week in Portugal on the 20th...I had to make a bit of a ruckus and get the site manager involved for them to rush the repair, since, well, really, they've had the camera a number of times, and after much discussion, they promised to have the camera back to me before I left for Europe.<br/> <br/> It worked mostly OK on the trip. I was shooting mostly scenics and AF in One-shot mode, or manual focus.<br/> <br/> Got home from the trip, and shot a sports assignment in AI servo. LOCKUP.&nbsp; Did the whole battery, CF, lens, Vertical grip strip-down and reattach routine and after five tries managed to fire off a couple more shots before it happened again.<br/> <br/> This was a Friday afternoon.<br/> <br/> I called Canon Jamesburg monday morning, spoke to a CPS rep, explained everything, and asked her when I could come down to Jamesburg and pick up a new 20D and vertical grip. I was told it didn't work like that, and that they would have to run the whole diagnostic to determine if it could be repaired, and that no one at Jamesburg could authorize a replacement unit. Based on a previous conversation, I had the name of the person at Jamesburg who was authorized to order a replacement, and then I asked to speak to the Repair supervisor. I got the same runaround.<br/> <br/> I asked for the telephone number of the Director of Repairs and Customer Satisfaction at the CUSA corporate office.<br/> <br/> I left a detailed message, with every repair number and explained that I expected a replacement authorization to be expedited by the end of the day.<br/> <br/> Then I called back and asked to speak to the CUSA CEO. I didn't get to talke to him directly, but I did cause a bit of a ruckus with his Admin and she put me through to the &quot;Presidential Complaint Call Center...&quot; whatever that means. I once again retold all my camera and repair woes and the guy promised to look into it.<br/> <br/> Meanwhile, the Director of repairs at Lake Success called back and told me that he had authorized the replacement, and apologized for the runaround.<br/> <br/> Two days later I dropped off my old malfunctioning 20D and grip and picked up a brand new camera and grip. The service record stated: '4th Repair attempt. Replacement unit issued.'<br/> <br/> I've had zero problems with the new gear so far (about 8000 shots...); however, I do feel that the camera is a little bit 'slower' all around than the original, but that's just a feel, not quantifiable.<br/> <br/> Cause a ruckus, see what happens.<br/> <br/> <br/> Mon, 12 Sep 2005 08:06:42 +0000 http://www.lightstalkers.org/canon-20d-lockup#7546 Re: Canon 20D lockup Thanks for the responses.&nbsp; Jiro,&nbsp; you need an assignment on one of our beaches!&nbsp;&nbsp; The worst the 20D did to me was fail when I was hanging out of a chopper about to shoot a flying Jabiru (black headed stork)- No Kinshasa rock throwers!<br/> <br/> I am definitely on the replacement route but I might try and negotiate an upgrade- I'll update with Canon's response.&nbsp; The 20D is getting a reputation for unreliability&nbsp;compounded by shoddy support.<br/> <br/> Thanks again,<br/> <br/> Dave Mon, 12 Sep 2005 20:33:55 +0000 http://www.lightstalkers.org/canon-20d-lockup#7566 Re: Canon 20D lockup My experiences with the pre-ordered 20D are a big reason why I have not preordered a 5D or a 1dmiiN...I'm going to let everyone else test it out for a while, and see what issues arise with either of these two cameras...<br/> Mon, 12 Sep 2005 21:07:27 +0000 http://www.lightstalkers.org/canon-20d-lockup#7568 Re: Canon 20D lockup Canon Australia just called and are acting pretty quickly once the problem was confirmed and are replacing my 20D.&nbsp; &nbsp;Jack's thinking is&nbsp;sensible considering any new technology and Canon's apparent use of customers as crash-testers.&nbsp;&nbsp;&nbsp;In this case I'm back at square one&nbsp; on my 20D so&nbsp;I have asked for a 5D upgrade price.&nbsp; I might be swapping a lemon for a cumquat but I'm hoping on a mango.&nbsp; (Apologies for the fruity analogy).<br/> <br/> Dave Mon, 12 Sep 2005 22:10:05 +0000 http://www.lightstalkers.org/canon-20d-lockup#7572 Re: Canon 20D lockup Yes.

Just hit the streets and got off about 20 frames before I got the "error 99" on my 20D, and it of course, stopped working (keeps shooting frames). This is the second time since December (when I bought two new bodies) I have got that error/problem and the forth time one of my 20D's has stopped working on me while on assignment. Just got my other body back that was in repairs for months because of the same problem. Good stuff...........

I have two 20D's bought in March. I've had one error 99. Also, perhaps one other error. Removing the battery, waiting a minute, and replacing the same battery cured the problems. Rare problem for me. I have heard speculation that the contacts in the lens can cause the problem. Two scenarios. One is use of non-Canon lenses. Other is letting heavy lens such as 70-200 hang from the camera which pulls the lens down in the mount. I have never, however, really read that anybody can nail those two scenarios down. Always turn off the camera when changing lenses. Always reformat the card in the camera before using. Be aware that the 20D isn't sealed as well against weather as the "pro" cameras. Remember, too, these are prosumer cameras, not pro cameras. I back my 20D's with a 1DmkII but only use when necessary (sports, etc.) because of the weight. The Canon 5D may well have issues as the 20D since it, too, is not a true "pro" camera. Oh, and my Leica M is always with me. Heh. Tue, 18 Oct 2005 07:52:09 +0000 http://www.lightstalkers.org/canon-20d-lockup#9017 Re: Canon 20D lockup I've heard there may be two reasons for Error 99's. I've had a couple in the past and the turn off/battery out/pause to use favourite curse/battery in/turn on method has always worked. One is the gold contacts on the lens mount (or your lenses) simply need a clean - the Error 99 is because of some communications glitch between the lens and camera. Or in Jiro's and Erin's case, maybe it's humidity or moisture causing the error? Or maybe the 70-200 'pull' mentioned? The other more depressing reason is it could be a warning that your shutter is about to die : ( Not straight away...but its kinda like playing Russian Roulette from then on. This could be an urban myth (God knows I hope it is) but if you've really been hammering your camera with thousands and thousands of shutter actuations, it's maybe possible as there's a limit to the number of shutter actuations in these things before failure. If it makes you feel any better I've had a 5D for just over a week and had my first corrupted CF card yesterday. DOH! Just for reference, if you don't have it - get Photo Rescue software by Data Rescue if your cards fail. It's saved me several times...including yesterday...phew.

Tue, 14 Aug 2007 07:16:13 +0000 http://www.lightstalkers.org/canon-20d-lockup#86121 Re: Canon 20D lockup My 20D gave out after around 120,000 frame count last Friday. The shutter fires by itself and I had to take out the batteries (I use a vertical grip) to stop it. That's the first time it happened in the two years since I bought it. Right before that happened I got "Error 99" messages several times and I rebooted and it was okay for a while until it finally conked out. The Canon factory repair center (in Jamesburg, NJ) said the whole mirror-shutter box needs to be replaced and it will cost me a mere $155 and the fix will take five days. That is, unless there are other serious issues with it that will drive the repair costs up and it might not be worth it. Canon will let me know whether it will be just $155 or more. FYI.

I've had two 20Ds for two years now, and on occassion in humidity, especially when leaping from air conditioned car into hot humid conditions I'll get an error... not sure which error code, its been a while, but I'll pull out the batteries (or battery grip) and wipe down the connectors, as well as lens connectors if necessary, and it seems to resolve things. Error 99 means lens problem I think, check manual, but when my lens crapped out it gave an Error 99. Wed, 15 Aug 2007 11:58:25 +0000 http://www.lightstalkers.org/canon-20d-lockup#86323
