Canon 8mm, Super 8, 1014 Electronic; 518 SV; 512 Cine Zoom

There are some great deals here! Sorry for cross posting!

Thinning my collection! All cameras have been used by me, but probably not in the last few years. I usually grab my Bolex's or Beaulieu's. The real gem in this lot is the 512 Cine Zoom with Tele converter. It comes with a lot of neat original items! Please have a look!

This is after the fact , since the auctions posted at the head of this topic are over, BUT I have a question for those of you who have used the Canon 1014 ELECTRONIC:

I have seen a few of these recently for pretty decent Buy-It-Now prices on eBay , but I recall reading a while back someone on another forum had written to avoid the 1014 Electronic and 814 Electronic and either go with the older 814 or 1014 Auto Zoom cameras or the newer 814/1014 XLS cameras . It was implied that the 1014 and 813 ELECTRONIC camera models were more prone to the manual exposure disintegrating and in general being difficult to repair .

Is this a known issue with the Canon 814/1014 Electronic cameras ? Are these cameras more prone to breakdown and harder to repair ? I realize there are many factors to consider when purchasing a used camera : how well has the camera been cared for by the original owner, storage conditions, etc. which can affect how well the used camera may perform , but if I were to get an 814/1014 Electronic would it be less likely to be repairable if a problem developed ?

The manual exposure control problem is pretty much guaranteed to happen to all 814 - 1014 cameras with the pull-out knob.
They're not particularly difficult to repair but it will still set you back some $$$.

Ok, so it is expected that the auto/manual exposure pull-out knob on the Canon 814/1014 Electronic models will fail . This is good to know so I can take that into account when bidding on eBay . About much would this kind of repair cost ? Are taking about $100 ? -- $250 ? -- $400 ? So ,for instance if I know that the repair will cost around $200 , then if I buy one of the cameras for $100 from eBay I should mentally change the amount spent to $300 because I know I'll be sending it in to a repair shop to get the exposure knob fixed (among other things that "could" be wrong with an old camera , but the pull-out exposure knob being particularly prone to failure on the Canon Electronic models. )


Is the Manual/Auto Exposure set with the sliding switch on the older model Canon 814 Auto Zoom considered less prone to break down ? (and is it easier and less expensive to fix than the pull-out knob on the Electronic ?)

Repair price will depend mostly on who does the work.
If that is the only problem, a fair repair price would be between $100 - $125.

Thank you, that's very helpful to know an estimated repair price because I would now bid accordingly on any Canon 814 or 1014 Electronic or XL model with the pull-up exposure knob , knowing that it will inevitably need replacing (if it hasn't already turned to goop) .

I think I will be more likely to bid on the older Canon 814 Auto Zoom. The manual exposure slider switch seems to be more reliable (?) .


In the meantime I found this:

which shows the problem :

I'd be nervous about digging into a camera like that (I'm not at all mechanically inclined) so I'd certainly pay to have a professional do this job, but it's interesting to understand more about the process and what it is exactly that makes the manual exposure knob on the Canon "Electronic" models go bad.

In the tutorial on Takahiro Nakono's page it seems as if he replaces the old melted rubber piece with new rubber , but I'm wondering if some other material would be better to use (but what ? I have no idea) since it seems like the same problem with the rubber breaking down would happen eventually ... although if it takes another 30 years for the rubber part to decompose maybe it's not really my problem by then , and if there is still Super 8 film available 20 years from now (?) someone else gets to do all this fun research for themselves and it all starts again. 20 years ago I'm sure there were many people who would be shocked to learn that there are still people shooting on Super 8 and 8mm film in the year 2013 , so who knows ?

Yes, that rubber wheel is definitely the weak point of the original design.
If a person had a lot of free time to experiment, I'm sure an improvement to the design could be figured out.
Unfortunately, free time is a commodity I do not have!

Is it possible that the humidity trapped inside the camera causes this? The eyecup is rubber and you'll notice that this rarely occurs with it; with the exception of extreme circumstances. Maybe the fact that the eyecup is generally exposed to air and as a result has the opportunity to dry out is what protects it. Trapped humidity can facilitate fungus growth which can deteriorate the rubber.
