Question 1

What does MRC Nano mean on a B+W filter?

Accepted Answer

MRC stands for Multi-Resistant Coating — multiple layers of anti-reflection coating applied to both filter surfaces. The Nano addition means the outermost layer has a nano-scale hydrophobic and oleophobic treatment, so water beads off and fingerprints wipe away with almost no effort. It makes the filter noticeably easier to keep clean in the field compared to single-coated alternatives.

Question 2

Does a UV filter affect image quality?

Accepted Answer

A high-quality multi-coated UV filter like this B+W MRC Nano Master has negligible impact on sharpness or contrast in normal shooting conditions. The anti-reflection coatings prevent the ghosting and flare that cheaper uncoated filters can introduce.

Question 3

Is buying a used B+W filter worth it?

Accepted Answer

Yes — B+W filters are built with durable brass rings and resilient coatings that hold up well over time, making them a solid second-hand buy. At Camera-tweedehands.nl, every pre-owned filter is hand-inspected for glass clarity and coating integrity. We verify that the filter is free of deep scratches and document the condition in our inspection report. Every filter comes with a minimum 12 months warranty, so you're covered if anything isn't right.

Question 4

Can I use this UV filter as a permanent lens protector?

Accepted Answer

Absolutely — that's one of the main reasons photographers choose a premium lens protection filter like this one. The MRC Nano coating keeps the outer surface easy to clean, and the brass ring won't jam on your lens the way aluminium rings sometimes do. We have verified that this filter's glass is scratch-free and ready for permanent mounting.

Question 5

How do I clean an MRC Nano-coated filter?

Accepted Answer

The nano layer makes cleaning simple: breathe lightly on the surface and wipe with a clean microfibre cloth in a circular motion from centre to edge. For stubborn grease, a drop of lens cleaning fluid on the cloth (never directly on the filter) works well. Avoid paper tissues — they can leave micro-scratches even on coated glass.
