Initially I made this purchase in order to start with the filters before switching to other products and in the end I am not disappointed.
The unit is particularly well packaged, filters storage pockets are very practical, the ring multitude of different diameters to adapt to different targets is welcome.
I do not regret this purchase, the only downside careful not to accumulate too neutral densities "full" and / or graduates, in fact, they give it a reddish hue to pictures if you earn more than 2, the thing 'not found in other high-end filters. But making do well, we can avoid this, for the price of all, we will not complain!
