Good quality filters to reduce reflections
These are well made filters, the ring is very small so they don't cause vignetting even on wide angle lenses. These screwed smoothly onto my lens and stayed on securely. These circular polarizers only reduce the light a little, and once screwed on there is an outer ring that allows you to 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 look down into the water, making it look clearer and cleaner. It also helps provide a clearer sky image when taking photos outside. This is the “D” series filter, they also have a “K” series. I'm not sure of the exact difference between the two as K&F's own website doesn't really explain it. From what I can tell the "D" series (these) are a slightly more expensive design with more layers of coatings including water/oil repellent coatings on both sides. They describe these as "waterproof". Definitely well-made filters that do the job.
