Perfect. A good value for money. Allows to make very long exposure time (exceeding 30 seconds in the remote). Only flaw, as in 58mm, it is on a very small diameter, the most darkened area on the other by the position of the ring to see more, especially when it is to the max area in a very exposed landscape . Big advantage against the fact that it is a small diameter rotating ring has a diameter slightly larger to allow for shoot with 18mm without problems.
