Too many options

I wanted to adjust to the dock an objective of "C" series. This means I have 4 distance values ​​and 4 distances (0.2m / 0.6m ..... and on the other scale up the Zoom .... 17/28/50). Each of these intersections has then + and -20 values.

That means:
Replace lens. Software makes an adjustment if the FW is still current, etc .. value eg 17mm and adjust provide infinitely to +5. FW write, remove the lens and make test photo. Then it starts again from the beginning. The FW balance to the power happens every time (completely unnecessary).

Short: It adjusts itself to a zoom NEN Wolf. It is true and it comes to results, but it is at times badly by heart.

In addition, the settings of my D7000 do not fit those of Sigma. My camera was at the AF adjustment at +10, with Sigma I arrived at +20. Because the "stop" is coming to the camera and lens Sigma itself. If the time is a "abjustieren". I'm just a layman and thus ultimately overwhelmed anyway. If Festberennweite that would be a lot easier.
