Caveats
- K&F's page claims no X-pattern control, and a buyer review on that page reports an X past the ND400 mark. On wide lenses, stay below the maximum.
- The page names both 67 mm and 82 mm threads. Check the 67 mm marking on the product you receive.
- 0.2% reflectivity, against 0.1% on K&F's ND2-32 True Color.
