I have several of these UV filters with adapters,so i ordered this one because K&F concept general makes pretty good products. Well, this filter is going to replace the one I've been using because it is better in every way. First of all, the threads are less "gritty" than other companies one, and slides on much easier. Very easy to thread on and off the lens without any unwanted friction. Secondly, I like the textured ring in the middle, it sort of matches the Fuji camera and makes it much easier to grip than the one I'm currently using. While it is taller than other UV filters (see my picture, the K&F is taller), on camera it does not seem to take up much room, and remarkably, fits under the FujiFilm OEM lens cap much easier. It slides into the cap better. Lastly, I love the threading on the outside of the filter which allows you to attach a hood if necessary. A very nice touch and something sorely lacking from other filters.

As seen on pictures, it match well with fujifilm X100 front lens element. I can even use the fujifilm original cap over it. The only imperfections is the metal used on the filter is different from the fujifilm camera metal.

A filter that needs no introduction, excellent build quality,
is perfectly suited to the Fujifilm design, in my case a Fujifilm x100v silver.

The filter is professionally presented inside its dedicated box, graphically
beautiful and super neat, heralds the little jewel that we will find inside.
Top quality UV filter, the details are perfectly in line with the camera,
same color tone, same texture of the grip, it gives magic, does not ruin the aesthetics of our beloved Fuji, on the contrary, it makes it even more professional. How professional are the photos that “churn out” even with a filter mounted. We find greater sharpness, improved contrast and decreases the flare effect (a stylistic choice that I often look for, but it really takes a moment to disassemble the filter), the colors are bright and balanced. In addition, the filter protects the lens from dust and scratches, which is not a bad thing at all!
The writings that go around the filter are also very nice, delicate and not bulky.

The filter is simply mounted by screwing it to the Fujifilm lens, after removing the native ring
that covers the thread. I used the filter box just to put the original ring in it.
The front part of the filter is magnetic and allows you to add 52mm filters (always of the same brand if you want) to create other special effects depending on the filter you choose to mount.

The original cap fits well with the filter which is as if it were not there,
clearly it has a thicker thickness and the lens sticks out a little more but still remains super compact, an essential feature of the Fujifilm of this magical series!

In conclusion, I was truly speechless.
A quality filter worthy of being mounted on the Fujifilm, which embellishes its design
and helps to preserve the lens over time, which, as we know, is not interchangeable!

kf congcept delivered quickly today, the UV filter from K&F, which I use on my Fuji X100 Classic. The filter is only suitable for the X100 series.
Well packaged and quickly installed, the UV filter fits perfectly and looks great. The material quality and workmanship are of high quality. Other attachments must be removed. The product is recommended!

I love this lens filter! It immediately serves two purposes -- it is an adapter for the x100 series so it can screw on to the outside threads of the x100vi, and then it has a built in UV lens filter. It has an additional set of external threads so you can mount yet another adapter on top of it if needed.

I only wish that this were available in black. It will match a silver x100, and then provides an 'accent' if you have a black edition.

It's great to have this on and protect your investment in the camera. I put it on and will just leave it on. Color matches my X100V perfectly!

Like other K&F filters, no issue with image quality,
Very sleek looking on Fuji 100VI while it protecting the camera lens.
Highly recommend.

This filter from K&F Concept offers UV protection to your precious Fujifilm X100 Series lens. It is a top quality item: sturdy, easy to mount, perfect optics, no optical aberrations or problems. The silver color matches the camera perfectly.

One thing to know: do not get it for any other 49 millimeters lens mount: the threads of the X100 Series are proprietary so it won't fit.

I think it's a high-quality UV filter, possibly the best I've used in many years involved in photography. It fits perfectly on the Fujifilm X100 series, screwing easily and without friction, making it easy to install without adapters. The textured ring improves grip when handling it. The quality is evident in every detail, from the soft threads to the finish that matches the camera's aesthetics. In fact, it even has an external thread, so that other compatible filters can be stacked or a sunshade can be placed, which is usually very useful in this particular camera.

Excellent quality UV filter from K&F.

I have loads of various types of filters in my kit, many of which have come from different manufacturers over the years. In recent times however, I've tended to stick with K&F for this type of gear. It's always good quality, there's plenty in the range for whatever job you need it for, and basically it's a case of sticking with what you know and are happy with.

Good stuff, and on a quality/value-for-money basis.... an easy 5-Stars.
