I don't see any special bearing surface on the forward support of the Kirk. If you own one, does it actually support the lens and does it rub when you rotate it?


Yes, it supports the lens; it is coated with the same low-friction whatever-it-is that the full ring is coated with. No noticeable issue on rotation. (I have no idea how well this would hold up to extremely heavy usage, but I am unlikely to find out -- I tend more to wide rather than long overall... )
