Is there not adjustment for precise focus of the tube lens?

not really. It is adjustable using extension rig set shown. from aprox 145mm to 205mm from sensor to front of tube lens.
With the reverse dcr-150 setup. shorter length is sharper with less magnification
208mm gives more magnification 10x to be preciise but is less sharp.
As far as I know from the research I`v done. There is no sweet spot and fine adjustment is not a must, extension set is fine to play around with in finding a good balance betwwen magnifiaction and sharpness.
