PrimeCircle filters are diamond cut from German Ultra-White optical glass, the best quality solution for modern high resolution lenses! The parallel relationship between front and rear surfaces (important for the best optical performance) is verified with a laser interferometer and a densitometer is used for testing consistent density. To check proper light transmission is also used a spectrophotometer!
This Optical Clear filter is designed to provide protection
for the lenses and does not usually incorporate any effect.
Every camera and lens should have a Optical Clear filter
attached as a matter of course when shooting in dusty,
moisture, dangerous camera car and action shots.
The filter protects your expensive photo and cinema lenses
from damage of the front optical element.
