This problem was brought up some time back and I don't think the root of the problem that caused the inadvertent triggering of the flash when advancing the film was identified. After a bit of trial and error, I found that by ensuring that the flash is not turned on till it is securely (and I mean SECURELY - push the mount into the shoe firmly and lock it down tight!) mounted onto my 0.85 TTL, the irritating problem would go away. Having said that, I never had any problems at all with the SF-20 on my other 0.72 TTL irregardless of how it went on. I suspect a bad pin contact that causes a short in the TTL circuitry beneath the top plate is a possible cause of the problem. Let us know what you find out during the course of your investigations.
