However its action hardly convinced me and I had a little trouble to handle despite a fairly impressive rotating ring firsthand. There are finer and easier to "feel" and manipulate elsewhere for a similar price, takes a turn the ring to see the changes that are not so substantial compared to other filters of the same type in other brands rather deemed not to quote them and it is therefore difficult to get the right setting quickly accurately.

It is actually also very complicated and boring to clean. If those who have not yet arrived or still struggling I recommend chamois and possibly if it does not yet slightly soaked in white vinegar handkerchief before wiping with chamois.
