Then, off the cuff I removed the Hoya HMC UV filter (It seems they are being discontinued so they are inexpensive, but tests apparently show it's really good http://www.lenstip.com/113.15-article-UV_filters_test_Hoya_72_mm_HMC_UV-0.html )

The "Flares" samples in the linked review are not encouraging, though they rated it highly. HMC is Hoya's earliest version of multicoating. Enough for film era, not so with more highly reflective digital sensors. HMC was less effective than their SHMC , and the current Pro 1 Digital and HD coatings are better yet.

Still, there is very rarely a need for a "protective" filter, and no need at all for UV with digital sensors that don't produce the excessive blue reaction to UV that film did. It cannot improve lens performance and offers less protection than the hood, so why bother?

IMHO, YMMV
