I was going through a container of random photo accessories I had acquired over the last twenty of so years. There were useful, easily identifiable items such as batteries and SD cards to remnants of my film camera days and a few “WTF is that?” items. Within the container was a group of 72mm Tiffen filters I don’t recall purchasing or even using. Being that they fit my Canon 28-135 lens, I decided to try out my unused Polarizors. Below are the results of my findings.
