After much waited anticipation, I finally went down to purchase the circular polarizer for my Canon A85. As to attach the filter to the camera I also purchased a 52mm adapter ring, it’s an Astron CPL. I’m glad that I got the non-branded (non Canon made adapter) instead of the LA-DC52C (Canon made standard adapter), the price is cheaper by half and it fit just fine, the side printing says its for A70 but it’ll work just fine for A85 as well. Can’t wait for a sunny day and take this out for some shot : )
