This filter will work for that lens.

The native filter size for the P7700 is 40.5mm I recommend the Nikon 40.5mm filter instead. http://bhpho.to/JAWyRD

Yes, but you will need a 72-82mm step-up ring. This will also prevent you from using the supplied lens hood. I am assuming you are referring to the 24-70mm f/4 lens.

That is the correct filter for the 200-400 drop in holder.

This question has already been answered by several B&H customers. This is not meant to filter rays of any wavelength, but solely to protect the front element of an expensive lens with a piece of quality glass that will not affect your images. A quality product for a quality lens. The u/v filters available in the aftermarket will tend to modify the quality of your images. BTW, I just checked the Nikon website and could not find any u/v filters available. Just NC (neutral color) or polarizing filters. Other filters are available, for example, the Skylight filter, to reduce haze. So, you should be safe using the Nikon NC filters for your purpose. Hope this helps.

Industry standard would have this to 52mm with 0.75mm pitch threads. If you have further questions, please write us. [email protected].

No, the Nikon Neutral Clear Filter (67mm) will not fit the Nikon COOLPIX B500 Digital Camera (Black) because there are no accessory threads in front of the lens on the camera.

Nikon Neutral Clear Filter (77mm) is not same as the Arcrest protection filter. Arcrest is a line of Pro Lens Protection Filters from Nikon.
