This is the model I version of this lens. It has a 67 mm filter diameter and a built-in tripod mount. The included metal lens hood is of the screw-in type. The close focusing distance of this lens is 3 m.
The model II version of this lens (for more details see next page) has a 62 mm filter diameter, no tripod mount, a built-in lens hood and a close focusing distance of 2.5 m.
The screw-in metal lens hood can be mounted on the lens in reverse position and the lens cap then still fits on the lens respectively the lens hood (nice design).
