Dominik_m, Yes, I have considered buying one as you suggest. and having the CPU transplanted into mine. Thanks.

I have owned an EF since new (1974). About a dozen years ago I decided to use it since I had gotten away from photography for a few years other than family snapshots. I discovered that the electronic shutter speeds (two seconds to thirty seconds) no longer worked. The shutter would open and stay opened. After fooling with it for 15 or 20 minutes, could get it to close. The mechanical speeds (one second to 1/1000th) appeared to work. Honestly, I can not remember if I noticed if the meter was responding. I sent it to, I think ACR, and after evaluating it, they told me the CPU had failed and was no longer available. I had them replace the seals, clean it out a bit and return it to me. I have two other Canons - an FTb bought new (1972) and a perfect AE1 Program I inherited. I had both re-sealed and CLA'd. So I am not out of business. I put the EF in my display case with my small collection of non-user cameras and went on to use the others. But, damn, I miss using the EF and, recently, I got it back out. I have read about people who have them and I have not read of anyone having similar problems. And most seem to have bought them used. I know I can use it manually. The question is has anyone had this problem with his or her EF?

I have owned a Canon EF since new (1974). About ten or more years ago, I discovered that the shutter speeds from 2 seconds to 30 seconds (The ones marked in orange.) no longer worked. You often read that the long (electronic) exposure mode is one second to 30, but it is two seconds to 30. The camera would open the shutter and lock up. After fooling about with it for ten or 15 minutes, I could get it to close. The speeds from one second to 1/1000 appeared to work normally. I am unsure if the meter is working properly. I have seen on this site a large number of people who own these cameras and they have no problems. Most bought them used. I have inquired with a number of camera repair facilities, but none will touch it. I was told by a company I sent it to for evaluation, that the CPU had failed and there was no way to repair it and the CPU's were not available. It is not like I don't have other cameras. Among others, I have an FTb I bought new and an AE-1 Program I inherited. But I really like my EF and would like to have it working again. I realize I can use it manually, but that is beside the point. Any comments?
