I am trying to use my Canon 100mm f/2.8 USM (not L) plus the Aquatica Macro port with the focus knob below the port and not on the left side as usual, but for unknown reason the gear on the port doesn't touch the lens gear. It looks like the camera isn't centered inside the housing/port.
Does anyone tried that ? had the same issue ?
My idea to use that is make my job easy to use manual focus.
