i am having huge problems working out what the motorized crayford is sooooo expensive!!!
I am about to build a hand controller for focussing (my computer linked one is ok, but i think a hand controller would be better) , and thought i could adapt the r&P rigel one instead for a crayford. It is a 4mm shaft on the crayford, which throw in a coupler, and some stabilizing legs, then i can't see why they try and charge so much
