HOYA Filter NXT Plus 40.5mm 10-Layer HMC UV CPL camera filter
A 40.5mm UV and CPL filter with 10 HMC coating layers, Schott B270 glass, 98% transmission and a waterproof top coat on a low-profile frame
- Schott B270 glass delivers exceptional optical clarity
- 10-layer HMC multi-coating achieves 98% light transmission
- Waterproof top-coat allows effortless cleaning of smudges and water marks
- Low-profile 40.5mm aluminium frame prevents vignetting on wide-angle lenses
- UV protection shields front element from scratches, dust and moisture
Protection and clarity
The Hoya NXT Plus 40.5mm filter combines a UV shield with a circular polariser in one low-profile aluminium frame. It is built for photographers who want permanent front-element protection without adding vignetting on wide-angle lenses. The 10-layer HMC coating and waterproof top coat make daily cleaning quick and reliable.
Coating benefits
Ten layers of HMC multi-coating raise light transmission to 98 percent while suppressing ghosting and flare. Schott B270 glass preserves colour fidelity and contrast across the frame. The waterproof top coat repels moisture and allows fingerprints or dust to be wiped away without solvents.
Light throughput and limits
At 98 percent transmission the filter leaves exposure virtually unchanged, so it can stay mounted in most lighting conditions. The slim frame avoids mechanical vignetting on wider optics, yet the 40.5mm thread diameter restricts use to lenses with that exact filter size.

Questions about this item
How often will the waterproof top-coat on the Schott B270 glass need replacement?
The waterproof top-coat is a permanent surface treatment on the Schott B270 glass and does not require scheduled replacement; it enables easy cleaning of smudges and water marks throughout the filter's life.
What optical limit appears first when shooting continuously with the 10-layer HMC coating?
The 10-layer HMC multi-coating maintains a 98% transmission rate, so light loss remains minimal even during extended shooting sessions.
Does the low-profile aluminum frame trap heat during all-day use in bright conditions?
The low-profile aluminum frame is a passive mechanical component that does not generate or trap measurable heat during all-day outdoor use.
