Good quality filter for reducing reflections
These are well made filters, the ring is very small so they won't cause any vignetting even on fairly wide angle lenses. These threaded onto my lens smoothly and stayed on securely. These circular polarizers reduce the light only a little, and once they are screwed on there is an outer ring that lets you rotate the polarizer to get the best effect.
You can use these to reduce reflections from things like water, glasses and windows. Because it reduces reflections, you can see down into water making it look clearer and cleaner. It also helps deliver a clearer sky image when taking photos outside.
This is the "D" series filter, they also have a "K" series. I'm not sure the exact difference between the two as K&F's own website doesn't really explain it. As near as I can tell the "D" series ones (this one) are a slightly more expensive design with more layers of coating, including water/oil repellant coatings on both sides. They describe these as "waterproof".
