Hi Peter, I downloaded and printed out the link above some time ago but it doesn't contain any maintance about the electronic shutter. It's mainly for the copal shutter, a bit about the battery pack and a bit about the Expolux (a different beast) whoever it does mention lightly lubricating the channel the rotary blades rotate in. It also mentions a blade upgrade for the electronic version...BUT Sinar no longer support the electronic version and Sinar in Switzerland didn't even reply to an email!

Cheers Dave
