Sorry - I'm not joining a facebook group for more info on this. I am unlikely to be that helpful in this case. I am not certain that the f/stop data is even transmitted in a way that isn't an offset against a known minimum. I was under the impression that the lens id was transmitted and the focal length and so forth and from this the camera determined the f/stop but I'm likely confused. I know that with manual focus A series lenses the entire thing is done via the contacts not the data pin - but since you have a data pin then that may be ignored?

What would the point be of having the lens lie? EDIT: The example given on f/stop just doesn't make sense to me. I do edit the files for SDM conversion and in that case you are changing the bits that report the type of focusing system the lens is capable of using so that the lens lies and says it doesn't have SDM. I can't imagine a similar desired change to make - unless you can edit the focus at a given mm/distance.
