UV Protection for 46mm Threads

This screw-on filter fits lenses with a 46mm front thread. It blocks ultraviolet light that can add a blue cast to outdoor images and shields the front element from dust, moisture and scratches. The filter is built for photographers who want a permanent protective layer without affecting exposure.

3.3mm Ultra-Slim Frame

The 3.3mm frame uses double-side polishing to prevent vignetting, even on telephoto lenses. It threads directly onto the lens barrel and accepts standard 46mm caps and hoods. The slim profile leaves clearance for wide-angle hoods and does not extend the lens length noticeably.

28-Layer Coating with 99.6% Transmission

Twenty-eight multi-layer coatings on imported Japanese AGC glass deliver 99.6% light transmission while repelling water, oil and fingerprints. The hydrophobic surface makes cleaning easy and reduces reflections from the filter itself. The coating stack maintains colour fidelity across the frame.

Questions about this item

Does the 3.3 mm ultra-slim frame cause vignetting on telephoto lenses?

The double-sided polished 3.3 mm frame is designed to avoid vignetting even on telephoto lenses while maintaining image clarity.

Will the 28 multi-layer coatings degrade or affect image quality during all-day shooting in bright conditions?

The hydrophobic, scratch-resistant 28-layer nano coating maintains 99.6 % light transmission and reduces reflections without degrading during extended use.

My lens barrel shows a Ø46 marking — is that the only compatibility check I need?

Yes, a Ø46 mm thread size matches this filter; verify the diameter symbol on your lens barrel or under the lens cap before ordering.
