Rodenstock 67mm HR Digital Super MC UV Blocking Filter (Black Label)
Product Description :
Super thin 14mm glass for a smaller mount and minimal vignetting
Multi-layer coating provides very high light transmission and low reflection eliminating stray light and double images
Scratch-proof water-repellant and dirt-resistant extra coating protects the glass and does not affect light transmission
UV radiation is completely cut out while short-wave blue light very close to the UV range passes almost without hindrance for improved color fidelity over typical UV filters
Brass mount resists typical negative effects of temperature variations and the high slide capacity means easy attachment and removal
