I was afraid I would have problems being a variable ND with rare effects, and zero problems. Neither on the corners, nor at ND400, the truth is that a pleasant surprise for its price. It may have a little green tint, but with a correction of nothing in the Premiere I fixed it, between 5 and 10 points on the dye tab towards magenta and you're done. Highly recommended, you just need to have a cap like the ND2 and ND32 models that are the ones I usually use.

I was afraid that it would have problems as it is a variable ND with weird effects, and zero problems. Neither in the corners, nor at ND400, the truth is that a pleasant surprise for its price. It can have a little green tint, but with a correction of nothing in Premiere I have solved it, between 5 and 10 points in the tint tab towards magenta and ready. Highly recommended, it only needs to have a top like the ND2 and ND32 models that I usually use.

Review for: “K&F Concept 72MM UV Filter — HD Ultraviolet Filter Scratch Resistant Lens Protector Filters with Lens Cap Cleaning Cloth for DSLR Cameras (Nano-X Series)” Brand: K&F Concept Size: 72MM The K&F Concept 72mm UV filter came in a plastic container inside a plastic-wrapped box, with a 72mm lens cap, wrist strap, and microfiber cleaning cloth. I checked on the K&F Concept Canada website and the price on the list (currently $36.99) is the same, although their website says a special price of $46.06. I always put a UV filter on the front of my lens to protect it in case it gets dropped. K&F Concept is a good name when it comes to filters, so I expect it will be decent glass as well. I'm impressed that it came with a lens cap as I lost mine. The plastic case with the wrist strap is great for keeping the filter safe when not in use.

For me this filter serves its purpose and it is currently the best filter at this price

While they tend to be lower priced, I've been pleased with the products that K&F Concept offers. Their 72MM Professional Photography Glass Filter Kit is no exception.

This is a great starter kit for amateur photographers. It can also be beneficial for semi-pro photographers. Although the filters are not of B&W, Hoya or even Tiffen quality, they are useful and functional. The kit includes a MCUV filter (this is just a fancy name for a UV or Ultraviolet filter,) a ND4 Natural Density filter and a CPL (Circular Polarizer Lens.) A nice additional touch is the included Cleaning Pen and 3-filter pouch. In fact, the filters come prepackaged in the pouch. This offers additional protection to the filters during shipment.

You can safely ignore the claimed compatibility with the Canon cameras. Filters are matched to the lens filter size and not to any specific camera. So, in this case, the K&F Concept 72MM Professional Photography Glass Filters should work with most any 72MM lens.

Fraction of the cost of a complete ND system. The craftsmanship is incredible. I own the 72mm and 58mm filters.

I have now also bought the 72mm version in the Lightning Deal and am equally satisfied with it. I now use the variable ND filters as “fast” filters for on the go. If I would like to expose even more professionally, I use my K&F Square Filters. These are also highly recommended!
The 72mm round filter shows similar good characteristics as its big 77mm brother. It has light colour engravings in the maximum range, but impresses with its consistently good image quality and workmanship.
________________________________________

The filter is very high-quality and comes with an extra sleeve. The filter is made of metal and glass. The two rings can be rotated against each other very smoothly.

For me the variable ND function works very well. Both discs are perfectly matched. I could not see any loss in image quality on my test images. The construction automatically results in a vignetting and sometimes a colour cast is created. However, nothing you could not quickly calculate with an image editing software!

I received the K&F Concept Nano-X True Color - variable ND filter in the size 72mm free of charge as part of the Amazon Vine program.

The K&F Concept Nano-X True Color - variable ND filter comes in a noble and robust packaging. This contains some details about the product as well as some general notes and information about it. Inside there is the variable ND filter itself as well as a storage bag and some information material.

The quality of the K&F Concept Nano-X True Color - Variable ND filter is very high and generally very well made. The thread, which is for 72mm lenses on my example, fits very precisely and can be screwed onto my lens very easily. The gray filter can be continuously adjusted from ND2 to ND32. This is very practical and space-saving because you can only have one filter with you and still cover a wide spectrum with it. The material from which the frame and the glass are made is very valuable and this is reflected later in the image quality. The adjustment works without any problems and in general there is nothing wrong with the product. This variable ND filter from K&F Concept is perfect for my needs. The product does a solid job and the image quality is very good. My expectations were exceeded and I am more than satisfied. Therefore, this product is also very suitable as a gift. This product is very suitable for hobby photographers as well as professionals. So 5 stars from me for that. TOP!!!!
