77MM CPL Filter 18 Layer Slim Circular Polarizing Filter Multi-coated Polarized MRC Filter

So I rarely use a polarizer filter but I keep telling myself that I should be and I need to learn how to use it. I was hesitant to spend a ton a money on a filter I may not like from trusted name brand filters I prefer but at the same time I hated the idea of using some cheap quality less than $20 filter because they usually don't work or have issues.

When K&F offered this lens I had to get my hands on one of them. K&F isn't a top premium brand, but they offer a good quality budget friendly beginner filters that are good quality lenses and features that some premium branded filters have but cost a lot more.

As to this filter its a great quality filter, its a basic multi coated (they offer a more expensive filter with more features that professional photographers may need). I haven't seen any quality issues or issues with images from the camera. My camera has some sensor issues in low light. Images sometimes have a lot of noise (when the settings say they shouldn't).

The picture I took are with the filter after some post editing to correct the noise issues and brighten up the picture (polarizing lens will darken images if you do not adjust settings, and still may darken anyways. It generally can be corrected in post)

I haven't really had the chance to use the filter during a day when it was bright and sunny and in the right position for the best pictures. But the filter does a great job at blocking glare on cloudy days.

The only issue I have is the lens attracts dust. I have to use a rocket blower, lens pen or microfiber cloth every few minutes to remove dust.

This a great filter for beginners and the average user but if you are professional with a bigger budget, I would look for a professional filter.

TIP: This filter is made to be able to rotate w/o unscrewing...make sure you realize there is a second/thinner ring that does the tightening to your lens. I didn't realize this at first and thought the filter was stuck on the lens.

I compared this filter to a competitors UV and no filter. Both at F4.0, 50mm, 1/1000 on my Sigma 17-50 f2.8 lens on my Canon. I could clearly see that the colors have more depth and richness to them. It is a lot more evident in the orange and greens of the plants in my photos. It does darken the image a bit but in well lit environments this will be on my lens from now on!

Filter arrived in a plastic hardcase, sealed in a plastic bag. Filter ring has a nice grip knurl for adjustment.

I am not a pro, I like photography and I am doing it as a hobby. Didn’t want to spend $100 for a expensive filter. Went with K&F for the price. High quality materials. Very slim . I was impressed. Got it in 82mm for tamron 24-70 g2. After getting this filter looked at K&F products and got few more things.

The quality is very good on this lens. It fit perfectly into my Osmo action 52mm cage. Even my lens cover that came with the cage fit perfectly. The quality of photos and videos produced with the lens on is just amazing. Overall very nice addition to my action cam.

Just brilliant
