I have a set of 23 used 55MM filters, a large quantity of new 72MM, and, a few new 77MM. These include just about any color, some effects,
and standard, circular, and wide-angle circular polarizers. I am looking for GOOD zoom lenses to fit a Canon EOS-1 camera. I may also
consider other accessories such as a power booster, battery pack,
command back, large flashes, or focusing screens. If anyone is interested, I can provide lists/prices for the filters.
