Each glass surface is vacuum coated with one layer of Anti-Reflection coating. This single layer helps to prevent internal ghosting and reflections. It also improves light transmission from approximately 92% (uncoated glass) to over 98%.
This filter uses our HSB mount made of brass. Various lenses for Hasselblad cameras are equipped with bayonets for the attachment of filters and lens hoods. The advantage of a bayonet mount over threaded filters is quick attachment and removal. HSB 60 and HSB 70 are offered.
