Stela Filter RI-PRO1 CPL 37mm having 37mm filter thread only. Polarizing Filter (CPL)  (37 mm)

Stela RI-PRO1 CPL Series Multi-Coated Circular Polarizing Filters are designed to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface such as water and glass. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy condition. The effect can be seen through the viewfinder when rotated at a particular angle minimizes the haze in the sky and enhances the color by reducing the polarization effect caused by sunlight. Slim design minimizes the likelihood of vignetting. Hardness of the filter’s provides additional protection in case of drops or situations where scratching could occur. When photographing glass buildings or landscapes with a water body in the frame, it can be really challenging to get rid of the reflections being caused by sunlight. Using a CPL filter can allow you to minimize the mirror image being caused by in the reflective element in your frame. All you have to do is simply rotate the filter to the required angle. Please check your lens manual or lens box for correct size as there are different size filters for different lenses and it is important to buy the one that is meant for your camera lens and not a random filter.
