105mm UV Protection Filter

The Nisi Air UV Protection Filter 105mm is a camera filter built for photographers who need maximum optical clarity. Its 99.9 percent peak transmission preserves detail on sensors exceeding 100 megapixels. The 48-layer ULRC nano-coating guards the glass against scratches, stains, water, and oil during outdoor work. A slim brass frame prevents vignetting on ultra-wide lenses.

Coating Durability and Light Control

The advanced 48-layer ULRC coating creates a hard surface that resists abrasion and repels moisture and oil in harsh environments. It blocks UV light below 395nm to reduce blue haze and improve colour accuracy. High-grade optical glass maintains sharpness without adding colour cast. The filter adds minimal thickness to the optical path.

Upgrade from Basic Protective Filters

This filter replaces standard UV or clear protectors that limit resolution on high-megapixel cameras or flare under strong light. The jump is worth it when shooting landscapes or travel scenes where maximum sharpness and clean transmission are critical. It is not for buyers who need a filter thread smaller than 105mm or who prioritise lowest cost over optical performance.

Questions about this item

How do I install the 105mm filter without vignetting on an ultra-wide lens?

Screw the ultra-thin brass frame onto the lens front thread; the slim 0.75-inch profile and knurled edge let you tighten it evenly so the filter clears the wide-angle field of view

What maintenance will the 48-layer ULRC coating need over time?

Wipe the nano-coating with a microfibre cloth and lens fluid; the scratch, stain, water and oil resistant layers clean easily and maintain 99.9 percent transmission

At what wavelength does UV blocking stop being effective during long outdoor shoots?

The filter blocks UV light below 395nm, so haze reduction holds up throughout extended daylight sessions without adding colour shift
