colin_fieldgate Posted December 9, 2002 Share Posted December 9, 2002 Today, a clear, sunny and cold (-1 deg C) day I had a fault occur twice with my EOS-1v. While in AV and AI Servo mode the aperture reading went to "00" and the shutter would not fire. The AF mode also went blank (not showing "Single Shot" or "AI Servo"). I removed the lens and re-fitted it and everything was OK again. The lens is a EF 70-200 mm f2.8 L IS with an EF 1.4 Mk II TC. Any ideas? Its like the camera believed there was no lens attached. Does this mean the contacts are dirty? They look spotless (outfit purchased in February and shot only ~60 rolls). Link to comment Share on other sites More sharing options...
paul_purcell Posted December 9, 2002 Share Posted December 9, 2002 Did you try installing a warm battery? Keep a spare in an inside pocket, and alternate them to keep the power supply warm and functioning. Besides that, haven't a clue, sorry. Link to comment Share on other sites More sharing options...
colin_fieldgate Posted December 9, 2002 Author Share Posted December 9, 2002 Interesting .... I had just put in a fresh battery about 10 mins earlier as the previous had failed mid 2nd shot!! Mind, IS lenses eat batteries, so I always carry 2 spares. Link to comment Share on other sites More sharing options...
isaac sibson Posted December 9, 2002 Share Posted December 9, 2002 Use PB-E2 with lithium AA batteries installed. The camera/lens combo you're using demands a great deal of current, and in the cold, that will be too much for a 2CR5 to handle, and the error you got occurs. Using PB-E2 should solve your problems.

colin_fieldgate Posted December 9, 2002 Author Share Posted December 9, 2002 I had hoped to avoid the extra cost / weight of the PB-E2, but as you say this lens combination probably demands it. Ah well, its almost Xmas!! Link to comment Share on other sites More sharing options...
roger_shrader Posted December 9, 2002 Share Posted December 9, 2002 You could try the BP-E1 instead of the PB-E2. It uses 4 AA's rather than 8, costs less and will put less of a strain on your neck. Link to comment Share on other sites More sharing options...
cjtower Posted December 9, 2002 Share Posted December 9, 2002 Why assume the battery is the problem? If you simply removed the lens and reinstalled it, and all was then o.k., it is not as though the battery recharged itself in the 5 seconds it took to do this. Did your problems arise right after connecting or disconnecting the TC? I had this happen off and on with an EOS1 when changing lenses with/without TC is AI Servo, but never in any other mode. I don't know what caused it, and it did not appear to be temputature-related. I simply switched the camera off, then on, and all was fine. (the "00" should appear whenever you removed lenses/tc, and press the camera shutter half-way; this just indicates "no aperture found" -- and in this case it would be because, of course, there isnt a lens attached; however, this is also what people using telescopes and t-mount lenses on EOS see at all times, since the "t-mount" lacks EOS electrical contacts).

stepan_pylyp Posted December 9, 2002 Share Posted December 9, 2002 You're not the first person to report this problem. Check out the following posting: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003u57 It happened to me one or twice about 6 months ago but I haven't had any more problems since.

colin_fieldgate Posted December 9, 2002 Author Share Posted December 9, 2002 Hmmmmmm ... so maybe its the lens. I'll be in my local Canon dealer tomorrow, so I'll mention it. I sure hope its not something I am continually going to get now and then. Link to comment Share on other sites More sharing options...
eshifri Posted December 9, 2002 Share Posted December 9, 2002 It just means electrical contact between your lens and TC or camera and TC was lost. The first thing I would try is cleaning all the contacts with alcohol. Link to comment Share on other sites More sharing options...
bill_proud Posted December 10, 2002 Share Posted December 10, 2002 Colin, I'd have to agree with Carl, the lens is not seated and locked. Link to comment Share on other sites More sharing options...
rog21 Posted December 12, 2002 Share Posted December 12, 2002 I think Carl has it nailed also. The "00" is normal if there is no lens or if there is a manual device mounted. <BR><BR> For example, I shoot the FD-EOS adaptor and a FD 500 4.5L combination on my EOS-3 in aperture priority mode and "00" is what's displayed in the viewfinder. The Camera simply works in stopped down mode (though it isn't mentioned in the manual for the EOS 3 at all).<BR><BR> Clean the contacts and try again would be my first attempt at correcting the problem.

colin_fieldgate Posted December 24, 2002 Author Share Posted December 24, 2002 I have now checked with Canon UK Service Department. Apparently the "00" problem is due to a faulty IS system on the lens. The battery compsumption is also a concern. Looks like the camera and lens will be back to Canon after the Xmas break, Link to comment Share on other sites More sharing options...
chris rb Posted May 12, 2003 Share Posted May 12, 2003 It looks as if lots of threads on this subject have appeared, and since I am not sure if everybody read them all, here it goes for the sake of it. http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003TtE http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=004umw http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=004A7F http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003u57 Chris Link to comment Share on other sites More sharing options...
