Absolutely satisfied with the purchase, for the quality of the filters, for the fast shipping times and for the packaging of the kit, there is also a very comfortable cloth bag for storing the filters. However, what I appreciated the most are the rigid screw filter covers, once the filters are screwed in, even more than one stacked, they are small in size, comfortable and safe, I wonder how to have more these caps also for other filters that I already owned.

I haven't had much time with the filters. Normally I'm out shooting stuff several times a month but this time a year I have limited time. I had planned to use them on an hiking trip that got cancelled last minute. I did some test shots and checked the lenses for defects and didn't find any issues.

Instead of the normal hard case lens filters might come with, this one comes with a screw on cap for each end and a soft carrying case for extra protection. For those times I need more than the pinch style lens cap this screw on cap will help protect the filters. But it will take a few seconds longer to remove the cap.

Only issue I've found so far is that the after tightening down the filter to the lens I was only able to remove the filter with a lens filter wrench. There's just not enough grip surface on the non-moving parts to twist it loose.

I like the filter set and plan on purchasing more of the K&F Filters for my other camera lenses and I recommend their products. I will update this add once I've had a chance to get some more time with the lens filter.

excellent quality of finishes, and great photo quality. complies with the PL filter, not like others that all they do is darken the image

I have been using K&F Concept filters for several months and I have been very happy with their quality. This set of a UV filter, circular polarizer, and two lens caps is excellent quality and is very reasonably priced. In terms of optical quality, I can't fault these. They are top-notch, and easily comparable in quality to Tiffen filters.

The filter frames are made of aluminum alloy, which is strong and light; they screw on pretty smoothly but aren't quite as smooth as the heavier brass rings that you get with more expensive filters. Brass is a naturally less "sticky" metal but these aluminum frames work just fine, especially because they have sections with machined grooves on each side that provide excellent grip for your fingers to grab on to when screwing and unscrewing the filters. I usually rub a bit of finger grease along the threads every now and then just to provide a light bit of lubrication.

The screw-on lens caps are beautifully machined and provide excellent protection, but they won't be replacing my standard snap-on plastic lens cap for everyday use when I'm out shooting because I find that having to screw and unscrew a lens cap is too time consuming and fiddly. The polarizer filter and UV filter can, of course, be used with any standard snap-on lens cap - you don't have to use the screw-on ones.

These filters come beautifully presented in a foil-embossed flip-open cardboard presentation box, with a K&F branded microfiber drawstring bag included. They would make a great gift for a photographer, assuming you know what size filters they use on their lenses.

These are excellent quality filters and are well worth the price, so I highly recommend them.

Nice quality, and the polarizer does great, on sunny days.

They came with a protective back and front lid for your protection. I like that you can actually stack 2 to your camera. I highly recommend them.

Perfect for its price

This gives my high end Hoya, sing ray, and B&W filters an absolute run for their money. I can see no difference whatsoever with K&F vs filters from these other manufacturers in terms of image quality on both my canon rf L series glass, and my rare Olympus 35-100f2.0 zoom lens, which might be the sharpest lens I've ever used.

It's a useful kit having both the protection filter and the CPL filter, which appears to introduce no color cast to images. Very pleased with these products. If I need more high end filters, I will look at product from this brand 1st.

All I NEED to say about these is that I've removed the Hoya and B+W filters from my better lenses, and replaced them with K&F filters. I'm going to add that this filter "kit" is so well built and thought out, with the included METAL caps front AND back when not in use, are so nice that I've now bought several and will look to K&F for my filters BEFORE looking to what I used to consider my "go-to's" in the past. I love these things. Recommended!!!

Great product with a great price. Better than expected
