SIRUI 24mm Anamorphic Lens F2.8 1.33X APS-C Camera Lens (MFT Mount)

  • On Nikon cameras, this feature is known as "AF Fine Tune". On Canon and Sony cameras, it's known as "AF Micro Adjustment". Please refer to your camera's instructions manual to see if this feature is present..
  • Package Included: Lens Focus Calibration Card X 2.
