The PROMASTER Digital HGX Circular Polarizing 52mm filter allows you to remove unwanted reflections from non–metallic surfaces such as water, glass etc. It also will enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. The PROMASTER Digital HGX Polarizing filter does not affect the overall color balance of a shot.
I ordered this filter to replace one that I lost back in October 2014. Arrived quickly & in good condition. Worked well with my Tamron lens. I will say this one still does not screw on tightly (which is the reason I lost the first one!). With the lens hood on, filter stayed in place & I shot some great photos in Maine.
Works well and the dirt and finger prints come clean must easier then my other filters and lenses.
