I like to be extra careful with my lenses, in the hope that I can resell them for nearly what I pay. To this end, I use UV filters as an extra layer of protection(in addition to my paranoia :P ). Recently I was in California, and one of the Camera Shops had used UV filters very cheap. For some stupid reason, I only bought one for my prime. Now I am kicking myself as I just got two new lenses without UV filters.
In my current location, there aren't any nice shops like that, so I cant just take a ride down the road and pick some up.
Are there any places online that I can buy used filters very inexpensively?
