The cutting-edge Ultra-Low Reflectance Anti-Static (ULA) coating delivers ultra-low reflectance of 0.08% (Typical Value, 420–680 nm average), breaking the conventional 0.1% wall while providing effective anti-static performance to help prevent ghosting and flare.
Marumi will present transmittance, reflectance, and optical performance data using Typical Value specifications—providing you with transparent, reliable performance measurement you can trust.
Marumi Magnetic Slim is now expanding its diameter lineup to include 62mm and 72mm, in addition to the existing 67mm, 77mm, and 82mm options.
This expansion responds to strong user demand and makes the Magnetic Slim Series compatible with an even wider range of popular lenses without using the step-up adapter.
We are excited to announce the launch of the Marumi Focus Aid—a genuine supporter for astrophotographers. When used together with the Magnetic Slim StarScape Kit, the Focus Aid makes capturing sharp, stunning nightscapes easier and more stress-free than ever before.
We are happy to announce that we bring the acclaimed Black Mist and White Powder Mist in a conventional screw-in threaded filter format, widely available in 12 sizes from 40.5mm to 82mm.
An updated Marumi product catalog is now available, reflecting our ongoing improvement in providing the latest information and functional innovations.
