Good filters. Worked as expected. Kit contains all essential components and it is value for money. Delivered on time.

I bought this set to enhance my picture taking to a new level and they are wonderful! Fit like a glove and well packed! Exactly as described and would highly recommend them to anyone looking for some filters! The cleaning brush is an excellent addition that closes to keep it safe and secure in your camera case for when you need it! Well done K&F!!!

If you are photographing in very bright light, the neutral density filters can help by cutting the exposure and letting you use shorter focal lengths. A pen to clean the filter is included. Nice as I got the 40.5 that are very small and they get dirty.

It is wha it’s.

The CPL filter is probably my go-to especially when shooting interviews. It ry helps clean up those exposed spots on the face. The kit itself is really nice and quality material. The case durable and keeps the filters in place during travel. Love that it also came with the cleaning cloths.

If you’re new to filters like me this is definitely a good beginner/intro Kit learn how to use them and which to use in different scenarios. Thanks K&F for a great consumer level product that works!

I have to learn what each filter is good for, but they work as described.

I like the quality of the K&F products always top notch. The prices are good for the quality of the products.

I’ll start this review with a couple of points: I was already familiar with K&F Concept, as I have several of their lens adapters (available here and elsewhere) to use vintage lenses on modern digital cameras. So, I had an expectation of quality from them. Second, I’m pretty much a filter snob. I use a UV filter on all of my lenses as a combination image improvement step and a protective measure.
Those things being said, there are three basic filters that photographers should carry: UV/protective, neutral density, and circular polarizer. It’s convenient if more than one of your lenses use the same filter size, because you can just swap between lenses and sometimes stack them. The 55mm size I got works on two families of the vintage lenses I shoot with, and I had been lazy about getting the ND and polarizer to use with them, so this was a way to solve more than one problem. (This kit is available to fit a wide range of filter thread size).
I mentioned that I’m a filter snob. If you’re putting an extra glass surface between you and your subject, you don’t want it to reduce your image quality. For this reason, I’ve always used multilayer antireflective-coated filters. On first inspection, the K&F Concept obviously has a high quality coating. They are labeled “HMC,” which is a designation used by one of the major filter companies. It may be that that company makes these for K&F; if so, that validates the quality for sure. Looking through them, they are optically excellent. The filter rim is made with two knurled gripping areas to make it easy to install and remove. (These may interfere with installing some old-school lens caps that fit down over the barrel of the lens rather than clipping on) The polarizer rotates smoothly, and the ND4 is correct for a two-stop light reduction. The included case makes it easy to have the filters ready in your camera kit.
I like lens pens. Having a clean lens brush handy is a necessity if you shoot in the real world. But the cleaning tip is kind of amazing: It’s like having a microfiber magic wand to safely remove smudges from your optical surfaces.
So, overall I think this is a really nice kit and a great value. You can buy lesser filters for more money for sure. Consider the lens pen a surprise gift.

I have the 67mm size Concept set as well. This filter set is a very good quality product and excellent value on top of that. The filters themselves look and feel high quality, they are very easy to grip and install or remove, and the threads feel and look well-machined. The pouch included with them is a very nice touch on the part of K&F and it also exudes a quality build and feel. Photographically the filters are fine, they work well and I have not had any issues with picture quality. I highly recommend this series or sets of filters.

Excellent quality, great price , and easy to grip. They come in a nice case as well. If you're in the market for some new filters these will not disappoint!
