37mm 3pcs Slim Lens Filter Kit (MCUV+CPL+ND4 ) + Lens Cleaning Cloth + Filter Pouch Nano-Klear

Great quality for the price. Sometimes they do give a purple hue to the sky when you take a picture from the right angle.

Nice filter set. They’re well made, well designed. Comes with cleaning brush which is useful. I love that you can have these filters on and still be able to use the lens cover over it when not shooting. This ND is ideal for most needs. Good value

Overall this is a really good set of filters for this price. The set includes a UV, CPL, and ND4. I am a photography instructor and put a video unboxing with this review and some sample photos of average use.

UV filters are used to cut haze. It was effective at this but the effect is not as dramatic as seen with other filters because most cameras have UV filtering built into the sensor. Unless you are at a location with a lot of haze (cityscape, mountains/high elevation), you may not notice any difference at all. The CPL filter is two pieces of glass that rotate opposite one another to block glare. This set's CPL does a very good job with reflections on water, foliage, and glass. The ND4 offers two stops of light reduction. This allows you to shoot in very bright conditions or to use longer exposure. ND4 is a good level for someone who is starting out with landscape photography. Eventually you might want a variable ND or NDs of different strengths.

If you are a beginner, casual photography, or overall camera enthusiast, then this set is a great way to learn and experiment with filters in photography. If you are already advanced or want something with even better performance, then check into K&F's X or XPro series.

Nice treading, the UV filter stacks easily with the other filters. The CPL works just fine, not too dark for me, at all. I have not used the ND4, which is 2 stops of darkening btw, not 4 stops, as stated on their website. I love the brush, nice and soft!

Filters are as good as some of those costing 3 time more ....
There excellent quality without question !

I've been using K&F lens filters for so many years I can't remember when I started. This is my third UV filter - broke two previous ones and they did their job of saving my lens. Dropped the camera once and clipped a rock, other time someone jammed a tripod into it at a group photo shoot. Sacrificed the filter, saved the lens.

The ND filters are excellent, no spotting or banding and can be stacked. Polarizing filters are also top quality. Plus the kit includes a soft storage pouch for everything.

Also included is a lens pen with carbon powder infused reversible tip and brush. Such a handy kit.

Photos with these filters are sharp and clean as without the filter, which is a good thing because now I can add an extra hold and do long exposures during the day with ND, as well as reduce glare from shiny objects with CPL and the UV filter makes the sky stand out in bright colors.

The bag and cleaning tool are both a very useful addition as it is very important for image quality and by stacking 2 of these filters together you can have an extra SD card slot in the bag.

A long time ago I started looking for filters for my Canon camera which I now have with a 77mm Sigma 17-50 lens. And since I'm not a pro or anything like that, spending some money on filters and then giving them a more recreational use gave me one thing. So I started looking at 77mm filters cheaper and buying these.
In the box you have three filters, a purse to carry these filters without being filled with dust and a brush to clean them.
Filter:
The first is an ND 4 filter, typically used for longer exposure photos. In the use I've given it has given me good image quality with no rare tint too obvious. Nothing that can't be easily corrected with a little color retouching.
The second is a polarizing filter, the intensity of which varies by rotating the filter itself. This is mainly used outdoors to remove unwanted reflections or increase the contrast of landscapes. In this case it's quite dark, so you can also run the times of the ND filter. Here we already find a little more vignetting than in the previous filter, perhaps because this is variable instead of being a fixed filter as in the previous case.
The third is the typical ultraviolet filter, which is usually recommended more than anything else to avoid rubbing a lens, which costs a lot more than the filter itself. The pocket: okay,
it
's just functional and corresponds to what it serves. The 77mm filters I bought in my case fit easily and are great.
Brush:
A little like a little like a little, it's functional. You have two endings. One end has a silky finish and the other end is more of a regular brush with hair.

In conclusion, if you don't want to spend a lot of money on filters these will help you save and you'll have three pretty good value than what other brands would cost for just one.

The cleaning brush cleans well and is soft. But the other side with the cleaning velvet is special.
Usually only round here but two-sided once round and once triangular! This is extremely practical.
The filters work as they should. I was able to take excellent photos in the strong sun this morning and just now in the evening. The filter means you don't have to close the aperture that much.
That works really well. I am happy

PROS: I’ve went out and shot with them a few times and have already gotten good results. The ND and CPL help cut out nasty frequencies and aid in boosting contrast. The ND is great for sunny days and the CPL is best for areas with water, glossy surfaces, cars, trying to get computer monitors in your shot, etc. The ND and the UV live in my lens.
The UV is a must have to protect any expensive lens. Comes with a nice storage pouch. The filters are stackable which is handy. The cleaning tool is nice and works well. The brush retracts, and the microfiber tips are great for cleaning the hard-to-reach glass of your viewfinder.

CONS: The CPL filter can be very difficult to remove from a lens as the gripable part of the filter is very small but you’ll get it eventually.
The ND filter doesn’t seem dark enough given it’s rating but it’s still fine. The filters are very, very noisy when they’re being screwed onto the lens / each other. Just a small annoyance, but put them on in the car before your scare any wildlife off.
