Review: For the value buy - Amazing value for the money made with quality feeling metal and works great. While it doesn’t 100% get rid of some glare for the price it works amazingly creating a night and day difference. For the value, you can’t get any better. Sadly, the lens cap does not like staying on with this filter on but that isn’t a dealbreaker when you have a cheap lens filter, that will protect your lens
Review: Good Product - Vary good CPL with carrying case. Does what you expect it to do. No color cast. Smooth adjustability of the polarization to remove glare from where you don't want it. Helps to keep the sky from blowing out and stop reflections.

## Features

- Enhance Color & Contrast: CPL filter can enhance the color and contrast, and remove non-metallic reflections such as water, and glass to show the true color, especially used in white cloud and blue sky photography.
- Multi-Coated & Cleaning Cloth: 18 multi-layer coating reduces reflection, and glare and improves color saturation and contrast. The vacuumed cleaning cloth for the camera lens and filter cleaning is harmless for the equipment.

- Ultra-Slim Frame Avoid Vignetting: Only 5.3mm thickness frame, there is no vignetting even on wide-angle and telephoto lenses, and the CNC-non slip frame helps install and remove the filter easily.

Great polarizer for landscape photography! I have not been disappointed in any of my K&F Concept filters. The terrain really pops and creates the right amount of definition in color. I have stacked this with other filters and love the combos.
