Olympus Protection Filter - PRF-D37 37mm

Its main purpose is to protect the front element of your lens from scratches, dust, and smudges, acting as a physical barrier.

The PRF-D37 PRO features a multi-coating designed to minimize reflections and maintain high light transmission, so it has minimal impact on image quality. It is a clear filter and does not alter colors or add distortion.

This filter is compatible with Olympus M.Zuiko lenses that have a 37mm filter thread, including the 17mm f2.8 Pancake, 14-42mm f3.5-5.6 II, 14-42mm f3.5-5.6 II R, and 14-42mm EZ lenses.

No, this is a clear protection filter. It does not block UV light. For UV protection, you would need a specific UV filter.

Gently brush off loose dust with a soft lens brush. For smudges, use a lens cleaning solution and a clean microfiber cloth, wiping in a circular motion from the center outwards.

The PRF-D37 PRO is made of glass.

Multi-coated means multiple layers of anti-reflective coatings have been applied to the glass surfaces. This reduces internal reflections and improves light transmission, resulting in clearer, sharper images with better contrast.

Ensure you are using a lens with a 37mm filter thread and that the filter is aligned correctly with the lens threads. Check for any debris on the lens threads or the filter threads.

While the multi-coating reduces reflections, extreme angles of light can still cause some flare. Try repositioning your camera or using a lens hood to mitigate this.

Ensure the filter is clean. Smudges or dirt can degrade image quality. If the issue persists, verify the filter is properly seated and that no damage has occurred to the filter's coating.
