wilco and Alex thanks for the links, now I am there, just didn't see the converter site before.
Your website has become very nice, Alex. Wilco, I know that Alex knows his stuff, last year he was anouncing that he would do the converters soon, I just wanted to confirm, that this is possible now.
Thanks Telyt, I had the converter on the body first. Didn't try to move the lever though. I will remember this, thanks for the tip. Should one mount the lens wide open generally?
In this case, it seems that the ROM chip was the problem. I took it out and now it works fine.
