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.

The only test I have available to me to evaluate a polarizer is to use the polarized light from a current generation LCD monitor along with some non-polarized light to see what the filter eliminates.

The setup behind the two images that are part of this review is simple. I put a DSLR on a tripod in front of a set that included mostly polarized light from a monitor as well as a bit of non-polarized light from an accent light set to the side. I kept the ISO, aperture and shutter speed constant.

In one image, I had the K&F circular polarizer set to the minimum and the other snap is set to the maximum. I also included a histogram from both images to the right of where the computer monitor is in both images. The filter did a good job of filtering out the majority of the light from the monitor indicating it does a filtering polarized light.

While my test setup isn’t a laboratory and I expect a real lab such as DxO would smile at my test, it’s valid in the sense that I’ve had both good and bad results using it. I also used this setup to test the UV filter included in this kit and could see no change. I didn’t post images because if there are any small differences they wouldn’t be visible in a JPEG posted to the Web.

I rate both these filters highly. I could detect no color cast from either of them.

Please see attached images!

As you can see in the images, the filters knock glare and unwanted lighting. I honestly didnt think these would work as well as they are advertised but boy was I wrong! If youre a new photographer, this is a must have! I got the 49mm as I usually shoot with a 50mm. My camera is the Canon80D. Its easy to attach and unattach. Comes with a plastic container to store the filter which is great.

I totally plan on getting the other sized filters for my other lens. Totally recommended!

I have only taken a few test snaps outside, but so far I really like this lens filter. When I took photos of my backyard, the images where I used the lens were sharper and more true to color.

The lens also seems well made. It has a metal body, and comes in a thick plastic case for protection.

I'm very happy with it.

I usually get a hoya or some other inexpensive UV filter to protect my lenses. I saw this come up as a Vine item and thought I would give it a shot. Qualitywise I'd say they feel more substantial than some of my older hoya filters with regard to the sturdiness of the aluminum ring. It has a good quality knurling and is a flat black anodization or paint. It gives good traction for your fingers to screw the filter on or off or to spin the circular polarizer.

The UV filter is very clear with no visible defects and, as far as I can tell does not affect my camera's image quality or exposure values. This is exactly what I look for in a UV filter. Just something to protect my lens.

The polarizer is similarly well made. It turns smoothly and does exactly what a polarizer should to reduce glare.

For the price I'm impressed and will be ordering from K&F again.

This is my fourth, Vine and purchase of K&F filters after my first Vine offer I have found they are a quality filter. I got this one for the Tamron 70-300 I got on Amazon a month ago, I did not notice that this came with a UV also and had already got one. In my working days I used to get only B+W but in retirement I have to budget more carefully. I have found these K&F virtually indistinguishable from them and these are my go to filters now.

Used this with my Sony and so far it’s been great. Fits well but now so tight you’re unable to get it off again.

This filter has a real sense of security to it. I really love the quality of the material, the box it was delivered in and the plastic case to protect the filter itself.

The image quality, in my opinion, improves with this filter on (in good lighting).

I really enjoyed taking pictures as they were given a little more of a depthy feel to me.

So far, so good, I'm enjoying this and really appreciate the screw on mechanism. I tried the magnetic version, but over time, I felt like my lens was more vulnerable. So this one is great.

Not only a shield for the lens but on water, a very good way to darken shine.

I got this to use on my Panasonic 45-150 lens, which is the lens I use the most outdoors.

I misunderstood when I ordered this that the UV lens is also half the polarizer, but it works well. The UV filter fits the lens easily and smoothly, the polarizer attachment filter fits well, and works well at an angle from reflective surfaces.

The pics I shot using these with my Panasonic GX85 came out well with no optical aberrations. There are better quality filters out there, but they cost a lot more - this set is the perfect combination of price, quality and optical quality. I'm very happy with it.
