Dear Kem,

I don't know how old your instrument is, but with the HRZ-drive you can 
do it. Today the instruments come with a piezo-objective drive, I don't 
know whether there it is possible.  Of course both the piezo and the HRZ 
drive are additional (extra) components/features which cost a lot and 
are not necessarily there on a "standard" system.

Greetings     Gabor
