CPL Polarizing Filter - 49mm to 58mm

The CPL Polarizing filter helps to reduce/remove reflections from windows, glass, and water... In doing so, you also get more vibrant and saturated colors. It also reduces atmospheric haze.

This filter has a rotating ring; you will need to turn the filter to vary its effect.

You can find out the filter thread size of your lens by measuring the internal thread; it does not correspond at all to the focal length: for example, a 50mm 1.8 lens can have a 49, 52, or 55mm thread...
