Simple, practical and well, what can not be said of the other components of the system.

I have long been looking for a filter solution for the Nikon 14-24 and then opted for the Lucroit solution because I like the Mointageart and there is a wide filter selection. Of course, the adapter is only in connection with the Lucroit filter holder makes sense (see my review local).

The adapter is simply plugged in from the front of the lens, so the lens does not have, as with other solutions, are taken by the camera.
The adapter is firmly seated very well does not have to be screwed and other solutions (where it is the setting rings of the lens to be difficult, because the lens is distorted).

Conclusion:
+ Easy to install with good seat.
- The price is a bit high.

The review relates only to this ring, not to the complete system with filter holder and filters!
