Premium Pro 46mm HD MC UV Filter for Leica Summicron-M 28mm f/2

Our review of the Premium Pro 46mm HD MC UV Filter examines a compact, protective UV filter tailored for the Leica Summicron-M 28mm f/2 and other lenses with a 46mm thread. The bottom line: this filter is for photographers who want simple, reliable protection and modest UV reduction without altering color balance. Built from resilient optical glass and a low-profile pressed aluminum frame, it serves primarily as a safeguard for expensive front elements while maintaining sharpness and a high 97% light passthrough for most shooting situations.

Key Features

• Eliminates UltraViolet Light: Reduces UV haze in bright daylight scenes so distant details appear clearer and more defined.
• Protective Glass UV Filter: Acts as a sacrificial front element to shield the lens from dust, scratches and accidental contact.
• Resilient Optical Glass: Uses durable optical glass to preserve image sharpness and resist small impacts that could damage the lens itself.
• Low-Profile Pressed Aluminum Frame: A slim, pressed aluminum mount minimizes vignetting on wide-angle lenses while staying lightweight on the lens front.
• Multicoated 97% Passthrough: Multicoatings reduce reflections and maintain high light transmission so exposure and color balance remain consistent.

Who It's For

This filter is well suited to street, travel and landscape shooters using a Leica Summicron-M 28mm f/2 or any lens with a 46mm filter thread who want fuss-free, constant front-end protection. It is an especially practical choice for photographers who frequently change lenses or work in outdoor environments where dust and abrasion are concerns.

It is less appropriate for those seeking strong color correction, heavy UV blocking for film scanning, or specialty glass for extreme optical corrections; photographers with those needs should consider dedicated correction or specialty filters instead.

Pros & Cons

Pros

• Provides reliable physical protection as a sacrificial first surface for an expensive lens.
• Maintains image clarity thanks to resilient optical glass and multicoating.
• Low-profile pressed aluminum frame reduces the risk of vignetting on wide-angle lenses.

Frequently Asked Questions

Will this filter cause vignetting on wide-angle lenses?
Its low-profile pressed aluminum frame is designed to minimize vignetting on wide-angle lenses, so it should be fine on a 28mm focal length.

Does it change color balance or exposure?
Multicoating and 97% light passthrough are intended to keep color balance and exposure consistent, so you should see minimal change in normal shooting.

Is this filter meant to be a permanent protection or swapped out?
It is ideal as a long-term protective cover for the front element, but many photographers also swap filters when different effects or stronger UV control are needed.
