Photo Forum / General Photo Topics / Australian Photography / December 2004Praise the God of EOS a 20D brought back to life!
Since my 20D dies unexpectedly I have plugged the batteries back in - hoping for signs of life about every 6 hours. This morning it powered up! All my custom settings are still in it. I decided to apply the firmware upgrade 1.05 and do some tests to check it's functionality. Somewhere I read this problem could have been caused bu the 1.04 upgrade I applied a few weeks ago. I can't find anything wrong with it now! How odd. I'll still get it back to Canon but now instead of being able to demonstrate a dead camera... Hmm. Getting odder by the day. >Since my 20D dies unexpectedly I have plugged the batteries back in - hoping >for signs of life about every 6 hours. This morning it powered up!

Sometimes you need to leave batteries out of mobile computing devices for a longish time before they fully reset themselves. (I have NO knowledge of the 20D or any other DLSR but I understand they are mobile computers with some glass and mirrors). > Does Canon tell you the reboot sequence?

I guy in the US killed his 20D when he did a firmware upgrade with the lens on the camera. Several days later when he was about to return it, it booted up. I suspect you are right about the time frame. I shot 200 or so pics with the camera today and it works fine. Beats me!!! >No, Canon told me nothing.

A manual on one such device I owned referred to > it as the "programmers hole". The backup battery in this model is in the normal battery compartment. It didn't go flat because my custom functions were intact so the camera didn't re-set itself, it just powered up when it previously wouldn't. I'm not satisfied with the output images since the initial failure either. I ordered a EOS 3 film body yesterday and when it arrives, I'll get this one back to Canon. My gut feeling is that the sensor is the problem. Perhaps distorting in the heat of the day. 36 degrees today and the case I use for the camera in the boot of my car is over 44c which is outside the specified operating range of the camera. I don't know what temperature it can get to in storage but seeing as the camera is powered on even when switched off, I suspect the maximum storage temperature is the same as the maximum operating temperature... And it's only the first day of summer!!! Somehow I fear these 20Ds are not suitable for use in most of Australia during summer. I hope I'm wrong. Doug > Somehow I fear these 20Ds are not suitable for > use in most of Australia during summer. I hope I'm wrong. I think most electronics, and many humans are not suitable for use in most of Australia during summer! :o We had our first 41 degree day over the weekend <sigh> It's gonna be a stinker this year. -Chris D >My gut feeling is that the sensor is the problem.

You really shouldn't let cameras stew in that sort of heat. If you must keep it in the boot, my advice is to throw the whole camera bag into a $5 foam plastic Esky, to keep it from cooking. And if you're shooting film as well, you really should be doing the same thing for your film. > I don't know what temperature it can get to in storage but >seeing as the camera is powered on even when switched off, I suspect the >maximum storage temperature is the same as the maximum operating >temperature...

My 10D coped just fine with the 42c days we got here last summer. While you may well get weird behaviour from your 20D when the body is overheated, you'll most likely find that it returns to normal as soon as the body temperature gets back within normal range.

Perna condita delenda est > ---^----^--------------------------------------------------------------- That's all well and good Lionel if it were not for the fact all my summer work involves travel and shooting in the tropics or outback. I keep a thermometer in the boot and it often gets to 50C in there. Unfortunately outside in the sun it's not much better. I really don't have the option to stick my cameras in a bag of ice everytime they run hot. The indoor work is not a problem. I can shoot 1000+ frames a day. Move outside in the midday sun and it doesn't take long for the camera to heat up. I don't know what the solution is but if Canon stick their head in the sand like Intel have done over their CPUs running in cases under 38C... Plenty of Pros will soon enough dump Canon. My contention is that if a Multinational company sells products into a country where over 2 thirds of it's land mass experiences tempratures higher than the goods are designed to work in... They are working outside the law by selling goods unsuitable for the purpose they are intended. I can't afford to wait 3 days for a cameras to "return to normal" like this one did. Doug Hi Ryadia, I got the web space thing working at bigpond, and I didnt even have to waste hours on the phone to support, thanks for your help, I was nearly about to fork out more money to them until I saw your url. Now all I have to do is work out a website design (sigh) SignatureMichael Brown Melbourne Australia www.photo.net/photos/mlbrown > > I wouldn't worry too much.

Hence my suggestion of putting your gear in an eskie when it's in the boot of your car. > I really don't have the option to >stick my cameras in a bag of ice everytime they run hot. The indoor work is >not a problem. I can shoot 1000+ frames a day. Uh... I wasn't suggesting that you use ice. Just that you insulate your gear when not in use, to prevent the guts of the camera from getting stinking hot in the boot. >Move outside in the midday sun and it doesn't take long for the camera to >heat up.

I doubt it. It's a matter of physics. There is no brand of DSLR that's immune to the laws of physics. >My contention is that if a Multinational company sells products into a >country where over 2 thirds of it's land mass experiences tempratures higher >than the goods are designed to work in...

Ask me some time how international electrical manufacturers deal with having most of their market split between 220VAC & 240VAC countries. > I can't >afford to wait 3 days for a cameras to "return to normal" like this one did. I seriously doubt that the problem you had with your camera is a typical reaction to overheating. SignatureW . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

If you put the gear on the floor (not on the exhaust side), then thoroughly insulate above the gear (not below) then I would expect the temperature of the camera would approximate the shade temperature, rather than the inside cabin temperature. That should keep it below about 45C most places and times which is not too far out of spec, especially when non-operating (I know it is really "idle" rather than "off").

After having 2 Statesmans stolen, each with about 10 grand worth of camera gear in the boot, I now take it with me. > All photographers should buy wagons and drive around with the AC on. ;-) > > When I park, the gear comes with me, so temp is never a problem.

The Exaust therory is OK but why not just pull down the centre of the rear seat and let the air con flow into the boot? I use a LowePro Mini trecker back pack when I go into the bush. I'm doing a 6 day shoot next year and I intend to monitor the heat inside it closely before then to know what to expect. I don't have the luxury of parking a Statesman under a Gum tree during the day. Several days hard slog on outback tracks by 4WD and then several days walking and shooting. Hardly the Gold Coast! Along with the camera and grip are a 120 ~300 mm f2.8 lens, several other (Glass) lenses and a Tripod. I used to do this with a 4x5 field camera in my younger days. Even this digital outfit is on the edge of what I feel comfortable with now. My partners have to carry the camping gear and food. I had no trouble last year with a 10D but I lost some shots I'd have otherwise salvaged from the previous year's MF gear. Hopefully the extra image size will help this year... If the cameras keep going. > The Exaust therory is OK but why not just pull down the centre of the rear > seat and let the air con flow into the boot? I was worried about the temperature in the *parked* car. As you say, while moving along you would want to move the gear to the cooled cabin because the whole floor area gets hot, from engine cooling air as well as the exhaust. You really notice this with a 4WD moving fairly slowly in the desert. > > > >That's all well and good Lionel if it were not for the fact all my > summer [quoted text clipped - 31 lines] > having 2 Statesmans stolen, each with about 10 grand worth of camera gear in > the boot, I now take it with me. For the city I agree, but I had mentally gone on holiday already and my car was the most secure place - better than the tent!

That maybe because there is a small internal rechargeable battery that keeps power going to the internal memory (bios???). You can lose your settings if you let it go flat, or they go back to default at the next power-up /viz |
