Steve, when using a lens of this type, what functions remain automatic, and what becomes a manual operation to the cameraman? My brother (cameraman) is use to shooting with full auto on lower end cameras with century optics 2x or 1.6x. The gl2, xl2. xha1. I suppose there will be quite a learning curb for him.Is any additional support needed for the lens?
