Nice for camping where will fit my Bulky SLR - plus it’s accessories like extra battery - Compact Flash cards. On top of a water bottle and two heavy blankets and a thick laptop! It also has two metal clips in front of you need to clip extra water bottles, tools, flash lights, etc. the backing of the backpack and the straps are padded very good so it doesn’t hurt my shoulders when carry heavy bag. Very useful. By the way, it’s a lot of velcros inside the bag that separate the bags into compartments, so if I’m not carrying my SLR, I can just take all the Velcro out and just carry the necessarily I need inside the bag instead. i also like the rectangle design to have the bag standing upward while I stuff items in- also makes it easier to take things out.

Fits perfectly

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!

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.

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.

My review refers to the following product, which was made available free of charge as part of a product test:

K&F Concept Mini 3 Pro ND Filter & Polarizing Filter, 3-piece ND8, ND16, CPL Filter Compatible with Mini 3 Pro（Accessories：8*Mini 3 per propeller）

This Filter set consists of the following scope of delivery:

- 3 filter attachments (ND8, ND16 and CPL filter) in a padded transport box
- 2 propeller sets for Mini 3 Pro consisting of a total of 8 propellers
- a small screwdriver for mounting the propeller

Quality and handling of the set:

The Filters are stored in a padded, transparent plastic box and are therefore well protected against damage or dirt during transport.
The filters themselves are very well made and sit perfectly on the Mini 3 Pro gimbal. They are easily assembled. First you carefully turn the original cap of the gimbal anti-clockwise and remove it. Then you can put on the desired filter and lock it in a clockwise direction. The filters are printed on their frames with fine white lettering "Nano-X CPL" "Nano-X ND8" or Nano-X ND16" and are therefore very easy to distinguish.

The glass filters have a metal frame, yet they are extremely light (only 0.7 grams!) so they do not negatively affect the weight of the drone.
They are dustproof and waterproof, so they reliably protect the gimbal camera just like the original cover.

The two neutral density filters (also called gray filters) included in the set reliably reduce the light intensity that hits the sensor chip of the drone camera gimbal. This allows beautiful effects to be achieved when taking photos and videos.

The ND8 filter lets through 1/8 of the incident light, the ND-16 filter only 1/16 of the incident light. Beautiful effects (blurring, etc.) can be achieved with the exposure time.

The polarizing filter from K&F, on the other hand, ensures that reflections are reliably reduced. For example, in buildings with windows or on water surfaces. The polarizing filter also makes the green appear richer. This is particularly noticeable when filming or photographing forests or meadows. Even shots of the sky draw it much better. Since the Mini 3 Pro can pan upwards with the gimbal, great pictures of the sky are possible with the attached K&F polarizing filter. The K&F CPL filter can also be adjusted by adjusting the scale on the filter.

The enclosed 2 sets of propellers should enable a very low-noise flight when used. Since they don't differ much from the original in terms of appearance or construction, I keep them as a replacement.

Conclusion:
All filters in this set from K&F do their job very well depending on the area of ​​application and are easy to install or change. Therefore a clear purchase recommendation.

I rate the product 5 stars overall.
