ND filter is included, I still paid about CHF 420 back then, the price today is good. The quality is right.

For a quicker change, I would get another Canon Clear filter. The ND filter darkens a little even at the brightest level.

The filter is included. It can also be ordered separately in case you ever break it.

Canon V-ND filter (0 mm, ND / grey filter)

Good price, in comparison!
