As a beginner in photography, I wanted to test a cheap polarizing filter to see if it was for me and how it worked. In any case, I am very satisfied and really amazed at how intense the effect of the polarizing filter can be.
In the run-up I also read a bit about how it works and why polarizing filters don't always produce the desired wow effect - in the end it's all physics :-) I haven't regretted the purchase and I'm looking forward to trying out a lot more.

I've attached 2 pictures to show that it does what it's supposed to do. The colors are as they should be. In the park photo, it is aligned with the sky, because the light conditions were not perfect, the sky still looks nice and blue, you can't see any sun reflections on the flower.

I would buy this filter again for other lenses

I bought this filter mainly for the summer season to be able to take some interesting pictures in nature. As a rule, I generally work with UV filters, also to protect the coated lenses of my lenses from scratches and dust. However, for bodies of water or on very sunny days, for example, it is better to use a polarizing filter, as it reduces reflections from various reflective surfaces such as water, etc. Colors can also be worked out more clearly with it. I have tested the filter with 4 different Canon lenses and have not had a problem installing or removing any of them. The filter and the filter thread, in my case 58 mm, are high-quality and cleanly worked and the optical components also have no defects.

First of all, I assume that most people know what a polarizing filter is and take this knowledge for granted. I found out beforehand on the Internet (reviews, tests, YouTube videos from the well-known tech and photo channels) what polarizing filters are available in which categories. And what are they good for anyway? I will personally use them for a tech blog to filter reflections from product photos, but also for nature photography. the K&F Concept polarizing filter is a bargain.

So ordered and tried it out with the 46mm during a walk along the Rhine. The filter fits the lens very well.

Water reflections can be easily filtered out with a slight twist. The same applies to metal reflections. Of course only to a certain extent, because at 3:30 p.m. in the blazing sun, physics also has its limits. This can be seen in the examples. However, reflection is massively reduced, especially in the case of polished chrome and paintwork, when exposed to direct sunlight in the summer light. Just like polarized sunglasses, which follow the same principle. Personally, I find that the filter conjures up a wonderful, strong blue gradient, for which the polarizing filters are also often used.

Overall a bargain and I think it was worth it. In addition to filtering water and light reflections, depending on taste and degree, the slight ND effect and thus color design is a creative thing.

Since I'm quite a beginner in the field of photography, I decided on this filter because the price seemed attractive to me. I am overwhelmed by the effect of what can be done with it. The processing and handling is good. I would definitely buy the filter again.

Screwing on and off is no problem. The packaging is ideal for carrying in a backpack.
Significant reduction in haze/fog in the test round. First picture is without filter, second with. The only thing I haven't managed to do as a beginner is the blue sky.
For the price you can't go wrong.

I bought the polarizing filter out of curiosity. After many years of practical experience in urban photography, I can already say after the first test images that this polarizing filter is VERY worth experimenting with and can deliver wonderful results: Reflections are sometimes completely filtered out ;-) See my test images: first image WITHOUT - second image WITH "turned up" polarizing filter.
(The test images are NOT post-processed!)

REAL RECOMMENDATION! -> These polarizing filters are really fun!

As a "beginner photographer" I didn't want to spend so much money to test different filters.
I never thought that such a cheap filter could deliver such a result (see pictures).
And with a camera that is actually not designed for it.
Clear purchase recommendation.

I always say a picture says more than 1000 words. Here you get quality at a low price. It doesn't always have to be a brand. Clear purchase recommendation.

Very good quality at a really good price. I took over 200 photos today, mostly on cloudy days and with lots of water. Reflections have been greatly reduced and the clouds get rich blue colors. All in all, the photos are much more pleasant in color and not as bright. I am thrilled and can recommend the filter for my Lumix.
