For filming with DSLR. I find the processing good. No "X" pattern, I'm satisfied
I knew as soon as I opened the envelope that I had bought a quality item. The beautiful black outer packaging contains a round acrylic container that can be opened at the push of a button. The filter rests on its foam bed. It looks like quality, it feels like quality.

Anyone who shoots video with a DSLR knows the camera settings and their limitations in brightly lit environments. This can become a bigger problem if, like me, you like to shoot wide open on a fast lens. On brighter days it was almost impossible to take pictures outside. To say I am very satisfied is an understatement.

Pros:
High quality, no dreaded X's or aberrations. I expected a lens of this quality to cost a lot more.

Cons:
To be honest, there aren't any. No, I can't put the lens cap on with the filter in place, but unscrewing it and putting it back in its case is no problem.

I'm just an amateur filmmaker so my word doesn't stand for photographers. However, from a filmmaker's perspective this is a great kit in the bag and for the money you can't go wrong.

this is awesome filter. picture quality remains perfect with the filter and great for protection you lens.
highly recommended

I bought a new lens. Of course, there had to be protection on it for safety.
I bought the k&f filter.
Top quality and top price.

I got this UV protection filter for my dslr lens after scratching another one. This lens is slim and fits well. It is great for adding a layer of protection to your lens. This filter comes in a very nice case for storage. I don’t notice a huge difference in my photos with and without, but the added protection for my lens is worth it.

UV filters are often used to block extended UV rays on the front of a lens and as a longtime photographer I remember the days when a UV filter was a must to protect your lenses over the long term. ...or at least that was the theory.

Unfortunately, much of this belief persists to this day, and while the benefits of a UV filter that provides protection is still a hotly debated topic, UV filters offer a very good benefit...they keep dirt/grime/fingerprints back from the front Main element of a camera lens.

In wedding photography, it's not uncommon for a child/baby/drunk adult to reach out and try to touch your lens...in fact, attempts to do so can produce some of the most incredible shots if the timing is right.

However, the expense and difficulty of cleaning a good, high-end lens is often many times more difficult than simply cleaning a lens cover on the front...which is where UV filters usually come in...they do the job good job direct contact with the actual lens.

I've used many different types of filters over my decades of photography, and among these, UV filters are probably the ones that offer the widest range of quality.

This is the first K&F filter I've used and I've been using it on a Sigma ART lens for a week.

I'm happy to say that this filter is a nice mid to high end UV protector. Unlike so many cheaper UV filters, this one doesn't seem to introduce any easily noticeable color shift or image distortion with the image.

While I'm sure if I start pixeling and comparing this UV filter to a $200+ filter I could probably find a few glitches here and there. In fact, this filter is half the price of many of the other upper mid-range filters.

... and let's be honest. The primary goal of a UV filter is protection. A decent UV filter shouldn't noticeably alter your images. In this respect, this product does exactly what it is supposed to.

One thing the K&F excels at, however, is the case in which the filter is packaged.

The case is a hard cylindrical case that is easy to twist open. However, the nicer aspect of this filter is the fact that the housing has a silicone ring with grooves in it that holds the filter in place while it is in the housing. This is something many other manufacturers do NOT (including a large number of more high-end filter manufacturers).

While yes, this is the first real experience with a K&F filter, for me...after looking at the attention to detail they have done, I am now in the market for a few others of theirs :)

This filter just helps keep the gunk off the front element. This protection helps keep the lens from slowly getting micro scratches and ruining the whole lens. Easier to replace a filter then a lens.

if you take pictures at night you have unwanted glare spots due to the UV protection filter, so it depends on how you hold the camera so that it is not too strong. When photographing during the day, with direct light (sun/lamp), I personally don't find the lens flare disturbing. It makes a clean, processed impression, it protects my lens, which is my top priority, so I can recommend the UV protection filter . I find value for money very good.

The UV filter has a high-quality and clean finish. I really like the blue-purple reflection and it really makes a difference. I didn't notice any changes in image quality, but there could be a slightly different, increased lens flare. If you like the look, you will be satisfied with the filter. In any case, I can recommend it as protection for the lens!
