the lens is in surprisingly-good shape, given its age
even has the original slip-on cap.... which is responsible for the slight rubbing marks at the top edge of the barrel you see in these shots
all the mechanics are in good shape - the focus ring is well-damped and does not stick or bind anywhere in its ridiculously-large path, nice snickety from the aperture ring....
only two faults that I've found: there is a cleaning mark/scuff on the bottom element (you can see it if the light is right, but hasn't appeared in any shots) and the focus ring grip is loose - if I don't grip it intentionally, it will spin in my hand...
