Kenko 77mm Instant Action Pro1D+ Variable Neutral Density & Circular Polarizer Filter

This ND filter provides a convenient way to control exposure by being able to vary the amount of light entering the camera from 1.5 to 9 stops while it can also control polarization. The filter replaces a whole set of several neutral density filters that saves your budget. VARIABLE NDX3-450+C-PL incorporates a new revolutionary magnet attaching system - "INSTANT ACTION".

Kenko PRO1D+ INSTANT ACTION is a revolutionary filter attaching system.

We believe that every photographer has at least once in their lifetime experienced the frustration of missing the perfect shot because it took too long to attach or change the filter. We believe if one could attach and detach the filter from the lens easier and quicker, the perfect shot won't be missed. Our mission is to free the photographer from the hassle of changing filters and make him focus on taking the best photos.

We are proud to present our solution - the Kenko PRO1D+ INSTANT ACTION magnetic attachment filter system. Not only does it free all photographers from the inconvenience of changing filters, but it will also greatly reduce the risk of filters accidentally dropping by screwing them onto the lens.

The system is very easy to use. All you need is an adapter and a filter. Attach the adapter to the lens. Once the adapter is attached, there is no need to remove it every time. Then, simply attach the filter to the adapter. You will not miss a moment.
