It's a nice filter, just like the other models I have from them. I needed another polarizer for my Sony E-Mount 55-210mm lens and seeing that K&F Concepts released another filter set I decided to give them a try. I was curious to see if I can tell a difference between some of their other polarizers. After some testing, I really can't tell a difference.

I took some shots of my neighbor's old Chevy pickup sitting at just the edge of my lens capabilities with the sun glaring down on the truck at the wrong angle. The filter did a good job and with some minor tweaking in the post edit, I was able to have a decent image.

I haven't had a chance to go out and do some shooting with this lens filter set but so far the at-home test has me impressed. The only issue I have is the lens filter ring is too thin. I can't get a grip on it to remove the filter. All I can grab is the circular part. I have to buy another lens filter wrench to remove it. But this seems to be a trend with this brand.

It gets 5 stars because it works and with the lens wrench I will have no issues removing the filter when I need to.
