Midwest Optical - Step-Up / Step-Down Rings

  • Step-Up and Step-Down rings
  • Adapter Rings

Product description

Step-Up and Step-Down rings make it possible to use filters with dimensions other than the filter thread of the current optics. Step-Up rings are especially useful when you have short focal optics, and then you need a larger filter to avoid vignetting.
