Marumi Fit + Slim 77mm MC UV Filter - Slim Protecting UV Filter

In this review the Marumi Fit + Slim 77mm MC UV Filter is examined from the standpoint of landscape and travel photographers who need lightweight, low-profile protection. The bottom line: this filter primarily protects front elements and reduces UV haze without altering color, and its ultra slim, 11g construction makes it especially attractive for wide-angle lenses where vignetting and extra bulk are a concern. Our review found it useful as a day-to-day protective filter that also preserves distant clarity.

Key Features

• UV cut at 390 nm: Cuts UV rays at the wavelength of 390 nm and under to reproduce clearer images of distant scenes and reduce atmospheric haze.
• Slim profile: The ultra slim, low-profile frame helps prevent vignetting on wide-angle lenses while adding minimal weight.
• Multi coating glass: Multi coating reduces reflections and helps maintain contrast and color fidelity in bright outdoor shooting.
• Secure lens cap holding: The frame design supports secure attachment of a lens cap so the filter remains usable as everyday protection.
• Eco-friendly construction: The filter and its smart retail case are made from lead free materials, which is a plus for environmentally minded users.

Who It's For

The Marumi Fit + Slim 77mm MC UV Filter is best for photographers who regularly shoot landscapes, travel scenes, or any outdoor subjects where UV haze can soften distant details and where a slim, lightweight filter matters to avoid vignetting. It suits owners of lenses with 77mm threads who want passive protection without changing exposure or color balance.

It is less relevant for those seeking creative filtration (polarizers, ND filters) or who require heavy-duty, weather-sealed filter systems; pro users wanting the thickest possible protection or specialized coatings may look elsewhere.

Pros & Cons

Pros

• Reduces UV haze at 390 nm and below, improving distant clarity in many outdoor conditions.
• Very light at approximately 11g, so it does not noticeably affect lens handling or balance.
• Satin finished frame and multi coating glass help minimize reflections and maintain image quality.
• Eco-friendly packaging and lead free materials make for responsible sourcing and storage.

Cons

• As a slim everyday UV filter it offers protection but does not replace purpose-built weather-sealed or heavy-duty protective accessories.
• Only provides passive UV correction; users needing polarization or density control must buy additional filters.
