Helderfilter B+W 007 MASTER 5,2 cm Multi Resistant Coating

The B+W 007 MASTER Clear camera filter with a 5.2 cm diameter provides straightforward protection for photographic lenses while preserving image neutrality. Constructed to sit in front of the lens, this clear filter shields the front element from dust, moisture, scratches and accidental contact without altering exposure or color balance. The Multi Resistant Coating (MRC) minimizes reflections and improves light transmission to retain contrast and sharpness in a wide range of lighting conditions.

Advantages

The Master Clear filter delivers physical protection of the lens surface with minimal optical impact, keeping images free from color cast and preserving original sharpness. The Multi Resistant Coating reduces surface reflections and facilitates easier cleaning by repelling fingerprints and smudges. A slim, precision-threaded metal mount ensures secure, flush attachment to compatible lens threads and reduces the risk of vignetting on moderate wide-angle lenses.

Suitable for

• Everyday lens protection during travel and outdoor use
• Studio work where lens surface must remain pristine between sessions
• Photographers who require neutral filtration without altering colors or exposure
• Situations with frequent filter changes or stacked accessories

Key specifications

• Filter type: clear (protective) glass
• Diameter: 5.2 cm
• Coating: Multi Resistant Coating (MRC) to reduce reflections and facilitate cleaning
• Mount: slim, metal threaded ring for attachment to compatible lens threads
• Optical behavior: neutral transmission, no intentional light reduction or color shift

How to use

Attach the filter by aligning the threaded mount with the corresponding lens thread and rotating gently until securely seated; avoid over-tightening. Use the filter on the lens whenever you want to protect the front element from dust, moisture or contact during shooting. For portraiture, landscape, and general photography, leave the filter in place to reduce the risk of damage without affecting image characteristics. Clean the coated surface with a soft microfiber cloth and, when necessary, use appropriate lens-cleaning fluid following manufacturer guidelines.

Recommendations

To maintain optical performance, store the filter in a protective case when not in use, inspect threads for debris before mounting, and remove grit with a blower before wiping the glass. When using wide-angle lenses, verify that the slim mount does not introduce vignetting; if stacking multiple filters, check for mechanical interference and image edge darkening.
