Okay,

I have an old supak flash designed for canon ttl and not ettl. If I run this on a current canon body the canon will error. If I remember correctly one can either clip or mask off some pins to get a basic manual or auto flash.

Before I start experimenting does any one know which pins I should be masking? I think I only need one.

Thanks!

If you look at the flash shoe such that the big dot is at the top it is the left 2 pins that need to be masked. FYI
