David,
Your question comes in and it foolows my quest about the link between the
camera and lens.
Here is the page that started it all:
http://www.four-thirds.org/en/about/standard.html
Now, these are diagrams, very informative to me, a little less to you.
Obviously there is a com between the body and the lens but I believe, tha
autofocus is managed thru the actuator.
I have not yet the adaptor but my opinion is: because there is an option by
which the camera does not operate if the lens is off, there is a com at
startup. then the protocol to focus. Is the lens slave to the body or the
oposite? I believe in the first opinion, camera=master
Any how, the body powers up the lens.
There is a line of com with an "acccessory". Does the adaptor for the R lens
is to be considered in this class?
Today, I have tried to get som contacts with Sigma Tech, to be followed.
If only I could get the docs for te 4.3 design, arghhhh :)
