UV (Haze) 1A Multicoated 95mm Multithreaded Glass Filter - Slim Fit

In this review of the UV (Haze) 1A Multicoated 95mm Multithreaded Glass Filter the bottom line is straightforward: this is a practical, protective UV filter tailored for heavy, pro-grade lenses like the Canon RF 28-70mm f/2L USM and for creators who need a low-profile, multithreaded solution. The reviewer found the Grade 010 glass effective at reducing the bluish cast from daylight while remaining optically neutral, and appreciated the rugged metal ring and slim design that helps avoid vignetting on wide apertures.

Key Features

• Grade 010 Glass: Absorbs ultraviolet light and reduces the bluish cast of daylight without adding color or contrast, so images remain natural.
• Multicoated Finish: Multicoating reduces reflections and flare for cleaner results when shooting video or photography in bright conditions.
• Multithreaded Design: Allows attachment of additional filters or lens-mounted accessories without removing the UV filter, simplifying workflows.
• Rugged Metal Ring: A black, heat-treated metal filter ring resists dents and holds the glass securely for dependable protection in the field.
• Slim Profile: The slim design minimizes vignetting on wide-angle and fast lenses such as the RF 28-70mm f/2L USM when used at large apertures.
• Two Year Warranty: Includes limited coverage for peace of mind when using the filter as a permanent protector on expensive lenses.

Who It's For

This filter is aimed at photographers and videographers who use large, professional lenses and want a permanent protective layer that does not alter color balance. It is particularly useful for users of the Canon RF 28-70mm f/2L USM or similar wide-aperture zooms where a slim profile helps avoid corner shading.

Enthusiasts who seek specialist optical correction beyond simple UV absorption, or photographers who require variable ND or polarizing control as a primary tool, should look elsewhere or pair this filter with other dedicated filters, since this product is a neutral UV protector rather than a specialty effect filter.

Pros & Cons

Pros

• Neutral UV protection that reduces the bluish cast of daylight without introducing tint or contrast shifts.
• Durable, heat-treated metal ring provides reliable physical protection for expensive front elements.
• Multithreaded construction makes mounting additional filters or accessories straightforward and fast.
• Slim design helps prevent vignetting on wide-angle shots with fast lenses.

Cons

• Does not provide additional creative effects like polarization or ND, so it cannot replace those filters.
