B+W 62mm Master Clear MRC Nano 007M Glass Filter - Low Reflection

In this review the B+W 62mm Master Clear MRC Nano 007M is presented as a no-nonsense lens protector for photographers who want maximum optical neutrality and long-term durability. The bottom line: this filter is for shooters who want a permanently mounted, color-neutral glass shield with very low reflection and improved resistance to water and dust thanks to the MRC Nano coating. It protects lenses down to 17mm on full frame without introducing visible color cast or light loss, making it a simple insurance policy for everyday and travel use.

Key Features

• Black knurled thin mount: The thin-profile filter mount gives a better grip for mounting and removes vignetting concerns on wide-angle lenses while remaining easy to handle.
• MRC Nano coating: The multi-resistant coating repels water and dust so the filter stays clearer with less cleaning during shoots in wet or dusty conditions.
• No filter effect: Optical glass is highly transparent and color-neutral so images show no apparent light loss or color shift when the filter is left on.
• Good coverage on wide-angle: Designed to work down to 17mm on full frame, it minimizes dark corners on many wide lenses when used in its 62mm size.
• Authentication QR code: A new QR code is included to verify authenticity for buyers who want to confirm they received a genuine B+W item.
• ECO-friendly packaging: The filter ships in reduced-impact packaging, which is a small but useful benefit for environmentally conscious users.

Who It's For

The B+W Master Clear 62mm is best for photographers who value optical neutrality and continuous protection for their front element, including travel, street, and everyday shooters who prefer to keep a filter on at all times. Landscape and architectural photographers who use wide-angle lenses will appreciate the thin-profile mount and the lack of vignetting down to 17mm on full frame.

It is less relevant for users who require ND or polarizing effects, since this is a clear protector rather than an effect filter. Studio photographers who frequently stack specialized filters or need a variable filter solution may want to look at other dedicated effect filters instead.
