Classic SLRs Series : |
EOS-1 Series is Canon's flagship camera model which uses the autofocus EF/EOS system as the backbone. The Series which comprised of the original EOS-1 has evolved to the present EOS-1v (film based) to EOS-1D (Digital based) which widely acclaimed as the most used professional camera right now at the professional user's market. Here is a common Message Board designed specifically for Canon EOS-1 Series SLR model which aims for common support and sharing mutual knowledge among users. Hope fully it will see its worth in time to come.

Dear Sirs
I own an EOS 1 which has recently gone in for a service due to a fault with the electronic circuitry within the body apparently.
The problem first started when the batteries were loaded into the E1 Power Booster itself. The moment the batteries were pushed home with the contacts within the booster was when the LCD just flashed "bc". The terminals in the booster seemed to be getting warm the longer I left the batteries in the chamber. But this was only for 20 seconds or so, then I removed them
immediately. There was a "circuitry smell" inside the chamber of the booster.Having read your information with regard to battery issues and the "bc" flashing only, I thought I'd write to inform you that this seems to be a problem with the electronic circuitry which is apparently embedded deep in the body. Can you pinpoint what circuit causes this and why this occurs? Would this condition cause any further damage if the batteries had been left in the chamber and making contact with the booster terminals, as it was getting warmer? What specifically causes this "block" in the electronic circuitry? Is this a fault with EOS 1? What can I do to take precautions and prevent this from happening again? Is it to do with damp or moisture or it coming into contact with liquid or dust particles, etc?
I would be most grateful if you could advise me on this matter.
Kind regards
Chris Price.
Excellent website, exceedingly infomative and helpful!

Chris, in my personal experience, exposure of a camera to adverse conditions, namely: rain, salt spray from using the camera on the beach (number one major cause of serious problems), excessively humid (tropical) environments and others, can and eventually will contribute to a slow deterioration in electronic conductivity within the camera, leading to a fault. The EOS 1 and 1N are somewhat better sealed against the elements than, for example here, my old (but much loved!) EOS 5, which has a dry joint/corrosive flare that occurs whenever the camera is exposed to cold, damp (or wet) environments: its internal and external displays rapidly fade out. It has never been able to be satisfactorily repaired.
It would appear to my understanding from what you have said that there are dry or broken joints within the battery chamber or in nearby circuitry; either in the power drive booster E1 circuitry or, more chillingly, within the EOS 1 (or both). Beyond speculation, it is impossible to say exactly where the problem lies; only a complete disassembly of the camera by Canon — literally putting the camera "under the microscope" — would give a positive indication of the problem and the remedial action required. If it is an old camera, the cost of repair could well become uneconomical. It is a serious matter indeed if there is a smell accompanying the error message of "bc --- --- --- " flashing (possibly a short). When a camera has been used over many years and exposed to a medley of outdoor conditions, yes, one should expect there will be an electronic problem at one time or another. I chiefly strongly discourage the use of *any* camera and *any* lens: a) in the rain; b) at the beach where there is visible salt spray from the surf; c) placing the camera on or near sand or in an environment of wind-blown said; and d) leaving the camera outside in hot sun. Snow, too, has been known to work its way into the camera through minute openings, thus setting forth the slow and certain deterioration in function somewhere.
Whenever you change the batteries, get a torch and carefully examine the terminals inside the battery chamber at the far end. If they look dirty or corroded, the first thing to do is clean that dirt / corrosion off. I admit this can be quite tricky given the narrow and deep nature of the battery chamber. Improvising with a thin wooden spoon, at the end of which is taped a tissue dipped in methylated spirits and rubbed against the terminals can work. Also, remove the booster from the camera body and examine the interface terminals array and the contacts on the body of the EOS 1 for any abnormal appearance; clean them with a cotton bud dipped in methylated spirits (*DO NOT* scratch or abrade the terminals with any hard object). Commercially available contact cleaners cannot be recommended unless one has a professional electronic servicing background, as misuse could potentially harm metal and plastic camera components.
I must say I am quite horrified by the cavalier attitude shown by far too many people with expensive cameras, particularly at the beach. I've seen cameras put down on wet sand within reach of an encroaching tide, dropped on the sand, rolled by kids, given a cursory shake, then back stuffed into a backpack... It may seen inocuous enough to take a camera to the beach, shoot a few scenes and walk along; the damage is cumulative and often fatal to the camera.
Over time, the preventative "medicine" is simple. Keep the camera (any camera) away from moisture and high levels of humidity over extended periods; outside, look after the camera by placing a waterproof/weatherproof hood over it (if mounted on a tripod, as mine is), particularly if you must use it near sand at the beach or near saltwater; *never, ever* expose it to this hostile environment very especially if you can see salt spray blowing off the surf or sand being blown about you. At the first sign of a problem, remove all power sources and take the camera in for an examination; the longer you leave it, the potentially worse the problem can become. —grh.2.

Hi ya...I have a canon 350d...And have just brought a 540ez flash unit for the said camara....But now have been in formed that the 430ex is more compatable for the 350d than the 540ez as the 430ex will work in all modes for the 350d than the 540ez....I am reley getting confuse to the matter..Can you put me at ease....chris

The difference is the E-TTL metering, first seen on the Canon EOS 50E (discontinued). The second is the linking of the flash exposure to the number of focusing areas within the camera. The 430EZ and 540EZ provide A-TTL metering; there is no provision for the more advanced E-TTL metering or additional coverage of the extended focusing area (ie. from 5 points to 7 or 45). The 430EX flash will match the 350D much better than the 540EZ, which has its roots in the Canon classics of EOS 5, EOS 1/1N and EOS 1N RS. —grh.4. From : chris dark (Darkcj@hotmail.com)

May I ask the moderator, what are the 1st generation of EF lenses introduced with the EOS650 and 620 ? May of which are not live to today, I guess. Thanks. By the way, Great board and very very informative website on the EOS1n. Two thumbs up !

It is difficult to pin any number of lenses down as being the first generation of EF lenses concurrent with the debut of the EOS 650 and its later EOS 620 (both launched in 1987). The EF 28mm, released in April 1987, ties in well with the appearance of these two cameras. In 1989, the EF 50mm f1.0L (=> http://www.canon.com/camera-museum/camera/lens/f_lens.html)— one of the costliest lenses ever produced — was released and is still available; being a member of the 'L' series of lenses, it is much favoured by professionals for low light and portrait photography. There is no information available from Canon on the first/earliest of EF lenses; the best ones are those you can still buy such as the 20mm f2.8, 100mm f2.8 macro and a small number of others. —grh.7.

Dear Gary, thanks for sharing your thought. Can I ask you a question ? IS the EOS 500N a good camera ? I have been offered a very clean unit with a zoom lens but without a flash. If it is, what flash should I get ? Thanks. Next, is USD200-00 for all worths it ?

Karen, Questions enter a Pending state when submitted; this is to allow us to check content, as we often get SPAM-type postings.
The EOS 500/500N (1993) replaced the EOS 1000 of 1992, so these cameras are somewhat dated. However, the 500 sports an impressive list of features making it suitable for first-time users and those with more experience. The camera's small size appeals to many people, as does its unusual power supply: 2 x CR123A cells which are easier to come by than the larger 2CR5 batteries.
I would advise to have the camera checked by a reputable dealer on the premise of the unit's age. It may look cosmetically A-1, but with age, the electronics (shutter, particularly) can develop a lag, resulting in the introduction of exposure errors. The service should also look at any accrued internal deterioration due to exposure to the elements (rain, sea spray, corrosion, etc.). The lens mount should be thoroughly examined to exclude signs of heavy wear (scrapes and nicks, particularly around the inner surface) and all controls should be checked for correct and smooth operation. Parts, where required may be difficult or impossible to find and this should be borne in mind when looking to extended use of an older camera like this. Having said that, US$200 sounds reasonable (by the way, downunder, we deal in Australian dollars... :-) ). I can only recommend any of the current EZ-series EOS system flashes (with the exception of those designed specifically to work with the more intricate metering systems of current EOS digital SLRs) eg. 300EZ (may be hard to find) 430EZ, 540EZ (both are superb flash units), or the 380EX, which debuted with the now-discontinued EOS-50E.
