NiSi 72mm Round L395 SMC UV Filter camera filter

SKU CH-QXAP-D8C8X

A 72mm UV filter with 5.2mm ultra-thin frame and double-sided multi-coating to protect lenses and reduce vignetting on wide angles

  • Protects the front element from dust and damage
  • Ultra-thin 5.2mm frame minimises vignetting on wide-angle lenses
  • Double-sided multi-coating maximises light transmittance and reduces reflections
  • Premium Japanese optical glass delivers high clarity and a smooth surface
  • Front screw thread allows easy attachment of lens caps and accessories

What the filter is and who it fits

The NiSi 72mm Round L395 SMC UV Filter is a protective camera filter built for 72 mm lens threads. It uses Japanese optical glass with double-sided multi-coating to maintain high transmittance and reduce reflections. Photographers who want a durable, easy-to-clean barrier against dust and front-element damage will find it suited to daily shooting.

What the ultra-thin frame and front thread change

The frame measures 5.2 mm thick, which NiSi states is the thinnest available to minimise vignetting on super wide-angle lenses. Superfine dull polishing and knurling improve grip during repeated rotation. A front screw thread allows lens caps and other accessories to be mounted directly on the filter without removal.

The specification that decides fit

The filter thread diameter is 72 mm, so it only fits lenses marked with that size. Buyers whose lenses use a different thread diameter cannot use this filter without a step-up or step-down ring, which is not included.

Questions about this item

Will the ultra-thin 5.2 mm aluminum frame eventually loosen or strip with repeated mounting and unmounting?

The frame uses superfine dull polishing and intricate knurling designed to stay resilient through repeated rotation, so thread wear is minimal under normal use.

At what point does the double-sided multi-coating limit light transmission on wide-angle lenses?

The coating is engineered for maximum transmittance; the practical limit is the 5.2 mm ultra-thin frame, which prevents vignetting even on super wide-angle lenses.

Does the filter generate noticeable heat or affect exposure during all-day outdoor shooting?

As a passive optical glass filter it produces no heat and requires no power; it simply blocks UV light below 395 nm while maintaining high transmittance for visible wavelengths.
