Lens Accessories Filters

PrimeCircle professional filters offer to filmmakers, videographers and photographers a complete line of cost-effective 4 X 4” and 4 X 5,65” filters with high grade professional quality without compromise.

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!

Two sizes are available right now: 4x4” and 4x5,65” in a full range of Technical, Diffusion and ND Grad filters for the modern digital production needs.
