assistance if possible;
I purchased a canon C-16 Macro ZoomC10x12 12-120mm lens. It has an arriflex standard mount and
it does fit into my arri 16-ST bayonet opening. When I have the lens focused to infinity, and I have the zoom setting at 120, everything is in focus. With the zoom set at 120, I can change the focus down to 5' and even down to a few inches using the macro ring.
When I change the zoom ring downward to 12 or even 40, everything at about 20' to infinity goes out of focus. Any suggestions about how to adjust this lens? OR fix this problem? Or just live with it?
thanks to anyone and all.
