I took out my old Nikon lenses, and found the filter box with the price tag on it. The filter cost $199.95 about 12 years ago. I'm pretty sure my husband was duped by sale guy to get such a filter for the total novice as I was back to that time. I just played a bit with the camera, got annoyed, and bought P&S cheap one
It's Crystal Optics Super High Resolution multi coated filter, SAC 55 UV, made in Japan. I tried to google it, but got the result for CO's filters around 10 dollars.
This one produces stars, here is the picture crop :
I know nothing about filters, so could you tell me please if filters dropped the price since, or it still has the value? I like the star effect, and going to keep this filter, just would like to know what I have.
