Shel,
Pentax apparently makes two grades of filters. The basic filter just
reads Pentax. The higher grade filter is a coated filter. The coating is
the same SMC coating found on Pentax's lenses. This higher grade filter is
labeled SMC Pentax.
The SMC filters are solidly built. The 49mm filter ring mount is thin
but strong. The 67mm & 77mm ring mounts are quite massive.
