Sorry to trouble you John but thank you so much for the detailled instructions.
I will try this tomorrow. First I have to go and buy an eraser (been digging in the drawer but I can't find one decent looking eraser)
What I forgotten to mention earlier in the post was that; I was also using sigma 1.4x TC with the 180macro lens. There was no problem with this combo since the day I got them.
In my effort to troubleshoot just now, I have removed the TC, tried the lenses with and without the TC, with all the function buttons in the right place, the f-stop is on "A" and both cameras (K10D and K20D) was also switched to AF-S or AF-C.
That means, tomorrow I will use the eraser on all the contact points on the 180macro lens and the 1.4x TC too. Right?
Sorry if I'm beginning to sound silly, but I need/want to do it right.
