72mm UV Filter Ultra Low Reflection Tempered Glass Protection Lens Filter, Slim Lens HD Optical Glass Scratch-resistant, Ultraviolet Filters for DSLR Cameras Nano-X Series

I recently added this K&F Concept 67mm Ultra Low Reflectivity/MCUV protecting filter to my photography gear, and it's proven itself to be an excellent asset.

This dual-purpose filter provides an invaluable extra layer of protection for my camera lens. Whether I'm shooting outdoors in varied weather conditions or just trying to keep dust and scratches at bay, this filter adds a reassuring safeguard without compromising image quality. It effectively combines MCUV capabilities with ultra low reflectivity, providing crisp and clear images by minimizing haze and cutting down on unwanted reflections.

One of the standout aspects of this filter is its sophisticated nanocoating. The ultra low reflectivity technology ensures that glare and reflections are kept to a minimum, maintaining the natural color balance and contrast in my photos. This feature is particularly beneficial when shooting in challenging lighting conditions, as it enhances image clarity without altering the scene's original look.

I also appreciate the filter's included protective case, which is versatile enough to accommodate various filter sizes. This flexibility is a fantastic convenience for photographers who use multiple lenses and filters and want to keep their gear well-organized and protected during travel.

Moreover, the Nano-X line's renowned build quality is evident. The filter is sturdy yet lightweight, making it a practical addition that doesn't add unnecessary weight to my setup. The water and oil-resistant nanocoating is a blessing for easy maintenance, especially during outdoor shoots.

In conclusion, this filter is a remarkable choice for anyone looking to protect their lenses while enhancing photographic clarity. It’s a worthwhile investment for both amateur and professional photographers who demand the best from their equipment, or if you are just looking to keep your expensive lenses staying nice.

Let me preface this review by explaining how I use these filters. I’m a wedding photographer and my wife is often my second photographer. I shoot Sony and she shoots Fuji. We also shoot wildlife and landscapes. Between the two of us I have purchased 23 K&F lens filters. Since we are working photographers, and rely heavily on our equipment, this UV filters are pretty important. I have had 3 lens front elements saved by UV filters, and because of that they have been worth it. These have been situations where a lens was dropped during a switch and landed on its UV filter, a cat pulled down a camera strap and the camera and lens landed right on its UV filter and another incident where I was taking a group photo in a church and my slung camera hit a corner of a chair’s back rest. These are all situations where the UV filter saved the lens. In all situations I was able to unthread the filter, pick up the glass shards and keep shooting. The first two situations the lens hood actually broke too, and in the chair corner situation, the corner was at a perfect angle to fit right in and get the lens filter.

There have also been situations where I’m shooting in the rain, or near a fountain and I can just wipe water off the front lens element with a microfiber cloth without needing to take them time and very carefully clean it.

Regarding this specific UV filter, it lives on a Fuji 35mm f2, and is thin enough to match the small lens body. It’s super low reflectivity means that it’s very hard to put it in situations where it has any effect on the image. Basically, it’s there for protection and has a near zero effect on image quality. Nothing more to ask for!

I’m including photos of portraits of my Kitten where she is directly backlit and another where the sun is just next to her. These were both shot a the Fuji 35mm’s maximum aperture of f2. In the photos where the sun is just to the side of the subject you can see purple blobs that are not present in photos without the filter. It was actually very challenging to get these purple blobs! I had to shoot a ton of photos into the sun, and the purple blobs were only present in very narrow angles. I’m not seeing any haze or loss of contrast and the only downside to this filter is those very hard to create purple blobs.

I got this to protect my Sigma 150-600mm lens, and the 95mm filter fits it perfectly. The filter has some heft to it and appears to be made very well, with very good materials. I only took a few photos with it, but I didn't notice any real difference in my photos with the filter on, but I know it will do a good job protecting my lens.

Perfect filter. Essential to protecting the front glass on your lens. This filter does not affect the natural flaring of the lens and it's very low profile and lightweight! This is a must have for any photographer! Great filter quality like the rest of my k&f filters. 10/10 recommend

K&F Concept filters are great, made from really good quality materials with clear optics.
They're not the cheapest, but the old "you get what you pay for" saying fits here.
You get a really handy plastic case for it too which makes travelling with more than one filter much easier.
Fits on my Sigma 24-70mm lens no problem and you can still use the lens cap and hood as you would normally.
UV filters are a great way to protect your lens and reduce reflection, increasing detail.

Great filter

In everything I'm going to say below, there are sample images.

I'll start by saying that the package it comes in is very well presented and complete.
It comes with the typical vacuum-sealed microfiber cloth and the solid case that holds the ring, plus you can store other filter sizes in it.

Regarding the filter, I zoomed in and looked at the sharpest areas, confirming that the loss of quality is minimal or nonexistent, meaning it's a very good option for keeping the lens protected.

Although it surprised me, since you might expect a UV filter to lose some brightness (even if it's very small), the opposite happened. As you can see in the histogram of the photos I've posted, the brightness increases slightly, even giving me zebra in some areas of the curtain. A curious phenomenon.

Interestingly, when it arrived, it was so clean that the glass was barely visible; it looked like an adapter ring. I also didn't notice any color drift or any kind of tint. You can see in a backlit photo of my hand holding the filter that it doesn't change.

I've had several products from this brand, and they're reliable, just like this one. I would definitely buy it again.

There are very few universal constants in photography, but one of those universal constants is the use of UV filters to protect the objective element of expensive lenses. I know of very few photographers that don't use these in one fashion or another.

I got this in 82mm, which fits my Canon 24-70 f2.8 II perfectly. The overwhelming majority of my lenses are 77mm, but I get most filters in 82mm because of my 24-70, and use 82-77mm step-down rings for most of my filters. It actually helps avoid vignetting on my 77mm lenses, anyway, so it's a good idea to step up in filter sizes if you like to "stack em deep", lol.

The quality of the filter is, frankly, excellent. I've certainly paid more for filters that weren't as good as this, so there are no complaints on quality whatsoever. The threads are smooth and well machined, and it spins on and off effortlessly.

Like most UV filters, the color shift is negligible, if it exists at all, and being high quality optical glass, I could detect no distortion in the image. The main thing it does, which is protect the objective element of my lens, it does beautifully.

As someone that has as much invested in filters as many people have invested in their entire camera setup, I'm very picky about filters. They have to be good, and if they're not good, they get tossed. This is a fantastic UV filter that is worth the cost. At around $80 for the 82mm version, it's worth every penny. Highly recommended.

I was really surprised to see this filter was crystal clear and clean right out of the box. Other filters I have used have been dusty or foggy before first use. The filter has a low profile and the outside of the filter ring is very easy to grip. This makes it simple to screw on to the lens and remove it. I didn't notice any reduction in photo quality while using this filter. Very happy with the K&F brand and would recommend to all of my photographer friends.

This filter is from K&F Concepts' premium filter range. The company also offers a budget range. I have bought several filters and other gear from K&F, as they represent good value for money.

At AUD 78, this premium filter isn't cheap but is more affordable than premium filters from different brands.

I like to find a sweet spot between price and quality. Doubling the price doesn't necessarily make something twice as good. As a non-professional, punching above my weight and using extraordinary gear, I am satisfied with good-enough filters. At the very least, these K&F Nano filters are good enough and plausibly far better.

I installed the filter on my Sony FE 40mm f2.5 (see the attached images), which has a 49mm thread. One can fit filters directly on the lens, with the lens hood detached, or directly on the lens cap. I have chosen the latter because I want to retain the hood.. I probably don't need a UV filter on this lens as its unusual lens hood encloses the glass. The OEM lens cap fits snugly in the filter housing, so I'll leave the UV filter on.

This UV filter is pretty nice! It seems comparable to my other name brand UV filters. I typically buy Hoya ones, and this one sees every bit as good. It's nice and clear, and does not add any additional glare or reflections to my pictures. And it fits accurately on a 77mm filter thread.

Honestly, no real difference between this and the lens without the filter, which is kind of the point! And no real difference between this and other top quality filters.
