ProOPTIC 77mm Multi Coated UV Slim Filter 3.2mm

SKU CH-ZN1X-X7PT5

A 77 mm UV filter with multi-coating for 99% light transmission and a 3.2 mm slim frame that prevents vignetting on wide-angle lenses

  • 99% light transmission preserves image clarity and colour accuracy
  • Multi-coated glass greatly reduces lens flare and ghosting from reflections
  • UV blocking eliminates haze and bluish cast for true-to-life colours
  • Slim 3.2 mm profile prevents vignetting on wide-angle lenses
  • Protects the front element from dust, scratches and impact

77mm UV Slim Filter for Wide-Angle Lenses

The ProOPTIC 77mm Multi Coated UV Slim Filter is built for photographers who need front-element protection without sacrificing optical quality. Its 3.2mm ultra-thin frame prevents vignetting on wide-angle lenses, making it suitable for landscape and architectural work. The filter blocks ultraviolet light to reduce atmospheric haze and unwanted bluish colour casts in daylight scenes. A lifetime warranty backs the construction quality.

Limits of UV Filtration on Digital Sensors

Modern digital sensors already block most ultraviolet light, so the filter's primary optical effect is haze reduction rather than dramatic colour correction. The 99% light transmission figure means minimal exposure compensation is required, yet no filter can add light that the lens does not already gather. Multi-coating suppresses flare and ghosting caused by reflections between glass surfaces, but it cannot eliminate flare from bright sources inside the frame. Protection against dust, moisture and impact remains the most consistent daily benefit.

3.2mm Frame Thickness Prevents Vignetting

The 3.2mm slim profile is the specification that determines compatibility with wide-angle optics. Standard-thickness filters often intrude into the extreme corners of wide fields of view, causing darkening that cannot be corrected in post. This filter's reduced depth keeps the front glass clear of the image circle at focal lengths where vignetting typically appears. Buyers using only telephoto or standard lenses do not require this specific slim dimension.

Questions about this item

Should I pick the 77mm size for my lens?

Choose the 77mm diameter only if your lens barrel or cap is marked 77mm; the filter threads must match exactly.

What does the 99% light transmission figure mean when shooting?

It means virtually all visible light passes through, so exposure and colour stay accurate without adding density.

Does the 3.2mm slim frame prevent vignetting on wide-angle lenses?

The thin 3.2mm profile is designed to clear the front element on wide-angle zooms, reducing corner darkening.
