Q: 1. The current image for this 3-filter kit shows a Hoya HMC Super Circular Polarizing filter and says on the filter, made in Japan. Is this the filter that those of you who purchased recently received? If not, which Hoya CPL did you receive? Thanks!

A: Mine is made in Philippines (all 3)

Q: 2. Will these fit my Nikon D3300 with AF-S 18-55 1:3.5-5.6 GII lens as well as 55-200 1:4-5.6 GII ED lens?

A: Ooops. I should have looked before my first answer. It looks like both of your kit lenses have a 52mm diameter, so these filters will work for both without any adapters needed. My first answer still applies, for anyone who has lenses with various thread diameters.

Q: 3. Would this fit a Fuji 23mm f2 lens?

A: Yes it will!
