## Summary description

Circular polarizing (CPL) filter K&F Concept 55mm KF01.1155 reduces reflections and enhances color saturation for lens with 55 mm thread. Designed for use on compatible cameras and lenses, it improves contrast in landscape, outdoor and architectural photography. Easy to rotate for adjusting polarization and helps achieve clearer skies and richer colors.

## Long description

The Circular Polarizing (CPL) Filter K&F Concept 55mm KF01.1155 is a screw-on optical filter designed for lenses with a 55 mm front thread. It reduces surface reflections from non-metallic surfaces such as water, glass and foliage, while increasing color saturation and contrast. The filter uses a circular polarizing element that allows through-camera metering and autofocus to function normally when the effect is applied. The slim, rotatable frame enables precise adjustment of polarization to control glare and deepen blue skies in landscape and outdoor photography.
Advantages
This CPL filter minimizes unwanted reflections and improves image clarity without altering exposure metering or autofocus performance. It enhances color saturation and contrast, especially in wide-angle and landscape scenes, and the rotatable mount allows fine-tuning of the polarization effect. The compact, low-profile frame reduces the risk of vignetting on wide-angle lenses and the screw-in design ensures secure attachment to compatible 55 mm thread lenses.
Suitable for
Landscape and nature photography to deepen skies and saturate foliage
Outdoor portraiture where reflections from water or glass need reduction
Architectural and product photography to control window and surface reflections
Travel and street photography when managing glare is required
Key specifications
Filter type: Circular polarizer
Mount thread size: 55 mm
Frame: Slim, rotatable metal/full-profile mounting (material may vary by production batch)
Optical element: Polarizing film laminated between glass layers
Compatibility: Screw-in for lenses with 55 mm front thread
Effect: Reduces reflections, increases color saturation and contrast
How to use
Screw the filter onto the lens front thread until secure, taking care not to cross-thread. Compose your shot and then rotate the outer ring of the filter while observing the viewfinder or live view; the polarization effect will increase or decrease as you turn the ring. Stop adjusting when reflections are minimized and color saturation is as desired. For best results, use the filter at 90 degrees to the sun for maximum sky darkening. Remove the filter when not needed or when using polarizing effects may interfere with certain wide-angle exposures or when shooting through polarized windscreens.
Usage recommendations
Clean the filter surfaces with a soft microfiber cloth before and after use to avoid scratches and maintain optical clarity. When shooting wide-angle scenes, check for vignetting and, if present, consider using a slim-frame CPL or repositioning the filter. Store the filter in a protective case when not mounted on the lens to prevent dust and damage.
