Protective Glass 49mm UV Filter HD MC Glass Protection Lens Cover

In this review the reviewer looks at the Protective Glass 49mm UV Filter designed for the Canon EF-M 15-45mm F3.5-6.3 IS STM and other 49 mm lenses. The bottom line: this is a simple, effective protective filter that primarily serves as a physical shield and basic UV eliminator while preserving image transmission. For photographers who want a slim, durable barrier over their front element and minimal impact on exposure, this filter offers reliable protection and clarity without complex features.

Key Features

• Multicoated 97% Passthrough: Multicoating helps preserve light transmission so images remain bright while reducing surface reflections for clearer shots.
• Resilient Optical Glass: The optical glass resists scratches and provides a stable protective surface for the lens, reducing risk from bumps and dust.
• Eliminates UltraViolet Light (UV): The filter cuts UV to reduce haze and protect color fidelity in bright daylight conditions.
• Low-Profile Pressed Aluminum Frame: The slim aluminum frame reduces the chance of vignetting on wide-angle lenses and keeps the filter unobtrusive.
• Protective Glass UV Filter: Serves as a first line of defense for the front element, allowing easy replacement if the filter is damaged instead of the lens.

Who It's For

This filter is aimed at hobbyists and travel photographers using a Canon EF-M 15-45mm or any lens with a 49 mm thread who want a no-fuss protective accessory. It is particularly useful for outdoor shooting where dust, fingerprints and incidental contact are concerns, and for those who prefer to keep a slim profile on their setup.

It is less suited to photographers who need specialized optical effects such as ND or polarizing controls, or those who demand the absolute highest level of optical correction for professional studio work. For those needs, a more feature-rich or higher-grade filter may be preferable.

Pros & Cons

Pros

• Simple physical protection for the front element, lowering risk of damage during normal use.
• Multicoated surface with about 97% light passthrough maintains brightness and reduces reflections.
• Low-profile aluminum frame minimizes vignetting on wide-angle coverage.
• Optical glass construction offers durability and reasonable scratch resistance.

Cons

• Offers only UV reduction and physical protection, not variable exposure control or polarization.

Frequently Asked Questions

Will this cause vignetting on a wide-angle lens?
The low-profile pressed aluminum frame is designed to minimize vignetting on wide-angle lenses, though results depend on the specific lens and focal length.

Does the filter affect image brightness?
No significant loss of brightness is expected; the multicoated design offers about 97% light passthrough to preserve exposure.

Is this a replacement for a UV correction filter?
This filter reduces UV and provides protection, but it is primarily a protective glass filter rather than a specialty corrective element for advanced optical needs.
