recently got my first modern digital camera, a Canon R50 with a kit lens, along with an RF 24-240 lens. I'm a bit clumsy and had immediately picked up a K&F UV filter for my lens as damage protection. It helped modestly to remove haze in landscape shots in SF Bay, but added some ghosting in low light shots (common with UV filters) and is mostly unnecessary on modern digital cameras... As I mentioned, I leave it on to protect my expensive lens. As soon as I saw this CPL, I ordered it so I can switch between them depending on the situation. When I'm shooting on/near water or on/through glass, I put this filter on to get better, clearer shots. I'm still working on my photographer's eye, but so far I've noticed no additional distortion of color or clarity. As far as the features and build quality go, it feels very high quality for the price. It doesn't bend or flex if I don't thread it correctly, so I haven't threaded it wrong even after 10-15 installations. The hydrophobic properties are good too - I got caught by a sprinkler and the filter shed all but a few tiny beads of water, which were easily removed with a swipe of a microfiber cloth.

I almost returned it when I found out my lens came with a complimentary $50 Sigma lens UV filter. The optics on it are wonderful, but I'm about to go to Niagara Falls and I imagine I don't want to marry my lens cloth.

I thought - why not just test them both under the sink before sending it back? So glad I did!

As if by magic, this K&H filter drains and all the water disappears. The free Sigma filter? It sucks the water! And it's hard to get off!

If you received a free high-quality UV filter and stay dry 24/7, no upgrade is needed. Do you value versatility in all weathers? Buy this now!

Neutral density filters open up a world of options and possibilities in photography, their function is to reduce the intensity of light that reaches the sensor, ie it is used when there is too much light. The most common situations where it is used are as follows: When you want a longer exposure time to get the silky effect on the water. When you want to use a larger aperture And when you have a very exposed image, for example in a landscape photo with a heavily exposed sky, or to take a photo of a lightbulb is often used. As you can see in the photos, I made against a light bulb and against colored LEDs. Mainly I bought it to get the silk effect on the water or the sky because the movement looks very smooth as if fading. The filter is ND1000, so it removes 10 stops of light, allowing you to take photos with 30 second exposures or more in broad daylight. The filter is made of glass, so the quality is very good, unlike those made of resin. Thanks to this, there are no dominant lights or chromatic aberrations. Very happy with the purchase.

Filters are a great addition to your camera gear and can enhance your shots however filters are generally not cheap, especially as you go up in diameter. I have a bunch of Canon L glass including the 100-400L IS, the 70-200 F2.8L IS and the 24-70L f2.8. These filters fit the 24-70L f.28 with the 82mm diameter, however I mention the other lenses as they both take 77mm filters. Rather than buy 2 sets of filters (82mm and 77mm) which would be expensive, you can use a filter step down adapter which is relatively cheap and use the single set of filters on all 3 lenses. If you go this route I would recommend opting for a bronze filter adapter as these are less prone to changes in temperature so are less likely to stick.

Normally I go for B&W F Pro filters as these are extremely well made and of a very high quality. This K&F Concept set of filters however are of very high quality as well.

This set consists of 3 of your most common filters, UV filter, CPL and a ND filter. Each has its own use. I've met a lot of people who use a UV filter on their lenses for protection, in case they accidently drop of bump their lens, they would rather break the UV filter rather than the front lens component however UV filters do have their use. They slightly reduce the blue/grey casting caused by ultraviolet and are very handy when at height or photographing mountains causing slightly sharper images. I tested this K&F Concepts filter during a recent trip to the Rocky Mountains in Tennessee, taking photographs both with and without the filter and after importing the RAW files in Lightroom, there is a noticeable different once you zoom in on the image.

The CPL filter is used to reduce glare mainly when shooting water or metallic objects. Normally when you shoot say a pond with ducks floating on it, you will get the reflection of the duck or the sky from the water however using a CPL filter it reduces the glare and you can see down into the water.

Lastly you have the ND filter. Neutral density filters come in varying strengths with this one being an ND4 filter which is good for 2 stops of light. Say you come across a beautiful waterfall or fast running stream and you want to get that nice glassy water look that a lot of people take, this is when you would break out your ND filter, allowing you to take a longer shot which would give you that look without sacrificing any of the colors.

I've used cheaper filters before with varying degrees of success. With some you will notice vignetting or blurring towards the edge of the picture. This isn't a problem with these K&F Concept filters. They are well made and sharp corner to corner.

The K&F Concepts filters come in a nice little velcroed pouch and each filter has its own re-sealable plastic bag for keeping the filters clean. On that note this filter set also comes with a small lens brush for wiping away dirt and smudges that you inevitably get on them.

Overall this is a very good quality set of filters at an extremely reasonable price and I have no problems with putting them on my Canon L glass lenses.

Neutral density filters are an integral part of photography. They are used all the time, especially in landscape photography. You know these great pictures of flowing water that looks so “fluffy” soft — for something like that, for example, you need a neutral density filter.

A neutral density filter, or “ND filter” (neutral density filter), absorbs the light so that you can expose for longer. Because of this long exposure and the movement of the water, it looks so great.
Taking pictures with a neutral density filter darkens the incoming light and allows you to shoot better in very bright environments.
If you use a neutral density filter in bright environments, you can in return shoot with a wider aperture or longer shutter speeds.
You can achieve beautiful effects by taking pictures with a longer exposure time.
Pictures are usually overexposed if you choose a particularly long shutter speed.
With a neutral density filter, you can prevent this and take pictures with a long exposure time despite a lot of light.
As a result, movements become blurred and flow into one another.
For example, you can display water or clouds, as well as fast-moving objects, in a particularly creative way.

The K&F Concept Nano-X PRO series ND1000 filter impresses with excellent quality, it is delivered in a stylish case (magnetic closure). Includes a cleaning cloth.
I shot at the five pictures and numbered them. The difference is obvious.
The filter is worth the money, it is simply screwed on and even my lens protector still fits on it.
This filter makes you want more and gets full points from me!

These are actually two filters, one UV and one circular polarizing. You can use them separately or stack them on top of each other. These are well made filters, the ring is very small so they don't cause vignetting even when stacking both filters on wide angle lenses. These screwed onto my lens smoothly and stayed secure. They only reduce the value a little and once screwed on there is an outer ring that allows you to rotate the polarizer to get the best effect. The UV filter helps reduce atmospheric haze and makes the air appear clearer. Many people also leave a UV filter on to protect the front element of their lens from dust and splashes. The circular polarizer reduces reflections from water, glasses and windows. Because it reduces reflections, you can see right into the water, making it look clearer and cleaner. It also helps provide a clearer sky image when photographing outside. This is the “K” series filter, they also have a “D” series. I'm not sure what the exact difference is between the two, as K&F's own website doesn't really explain it. As far as I can tell, the "K" series (this one) are slightly cheaper with fewer layers of coating, the K series doesn't seem to have a water and oil repellent coating. Definitely well made filters that do the job.

Neutral density filters have become indispensable in photography. Especially in landscape photography they are constantly used. You know those great pictures of flowing water that look so "fluffy" soft - for something like that you need a neutral density filter, for example.

A neutral density filter or "ND filter" (neutral density filter) absorbs the light, allowing you to expose longer. It looks so amazing because of that long exposure and the movement of the water.
