B+W Clear Protection Filter 77 mm - Ultra Slim Titanium Mount

Our review finds the B+W Clear Protection Filter 77 mm is aimed at photographers who want permanent front-lens protection without changing image characteristics; the single biggest reason to buy is its near-zero optical impact combined with robust protection. In this review the filter's ultra thin titanium-color mount and the MRC Nano coating stand out: it maintains color neutrality and extremely low reflection so it can stay on the lens full time while shielding expensive glass from dust, moisture and incidental knocks.

Key Features

• Reflection-Free Titanium-Color Finish: The titanium-color finish reduces visible reflections and gives a premium look that complements quality lenses.
• Thin Profile Filter Mount: The ultra slim mount helps prevent vignetting on wide-angle lenses and is suitable for use down to 17mm on full frame bodies.
• MRC Nano Coating: The multi-resistant coating repels dirt and water so wiping the filter is easier and fewer smudges reach the glass surface.
• No Filter Effect: The clear glass is color-neutral and highly transparent, so it does not alter color accuracy or produce light loss.
• Permanent Protection: Because it maintains image clarity, the filter can remain in front of the lens to protect the front element from scratches and impacts.

Who It's For

This filter is best for landscape, travel and everyday shooters who want continuous front element protection without compromising image quality; professionals and enthusiasts who value image clarity will appreciate the neutrality and low reflection. It is also a good match for lens owners who prefer a premium look and solid machining, as the titanium-color ring enhances the appearance of many lenses.

Photographers who need specialized filtration (polarizers, ND filters, or specific UV correction) should look elsewhere, since this product is a clear protector with no creative filtering effect. If you frequently use thick adaptors or filter stacks, consider slimmer or step-up options to avoid compatibility issues.

Pros & Cons

Cons
