this is very interesting and smart solution to give new life to 80-200 zoom lens. I would like to do the same to my 80-200 because it is also affected by back focus and -20 is not enough to correct it. Could someone clearly describe how to disassemble the lens and have full access to the brush focus? Is it a simple operation or could potentially damage the lens? A picture that describe which screw to remove would be very useful for everyone. Thanks.
