I just received a Tiffen Digital Enhancing Kit. I was told that the kit included an ultra-clear filter that works like a UV filter, which is what I requested. Is this true?

Yes. We believe the filter you are referring to is the Tiffen UV Protector, essentially a clear filter that protects your lenses and provides basic UV protection that minimizes the bluishness you sometimes get when shooting on overcast days, in open shade, or taking pictures of distant scenes. This filter is included in all Tiffen filter Kits and can be left on your lens at all time to protect it from physical damage.
