@ludwigsdiana sorry Diana, I have looked back through my shots, and found this one Senetti image 1114, (see link below) where you ask about my lens, is this the one? My lens of preference is my AF-S micro Nikkor 85mm, however this particular image was taken with my old LB composer which uses magnetic discs for aperture. I believe for this shot I had inserted F2.8 disc some others maybe f8 disc but this does not communicate with the camera and defaults to f1.0 and focal length 0. Hope this helps. The above image was taken with my Micro lens. I am not sure what other questions you refer to.
@ziggy77 Thanks so much Jo, it all sounds so complicated and I have not even heard of these.. No wonder you get such wonderful shots, you sure know what you are doing :-)
