I'm interested in getting something like this with adapter rings to fit several lenses.
Yeah, it is the 100mm x 100mm (some filters are metric or imperial 4"x4" or 3.9"x3.9") filter holder. You can get different ring adapters such as 67mm 55mm or 82. They call the step down rings I think.

Those have significant effects on the image. I too would like to experiment with those filters too. Also, photoshop or Lightroom has the same filters for free.
