I recently ordered the K&F Concept 62mm ND Lens Filter for my photography needs and have been extremely impressed with its performance. The 28 multi-coated circular polarizing and neutral density filter is a game changer, allowing me to capture high-quality images with greater control over the lighting.

One of the things I love most about this lens filter is its versatility. The 2-6 stop range allows me to adjust the exposure as needed, and the polarizing effect helps to reduce reflections and increase contrast. The 62mm size is also a great fit for my lens and the multi-coated design helps to reduce any flare or ghosting.

In terms of build quality, the filter is well made and feels sturdy in my hand. It's also easy to install and remove, making it a breeze to switch out as needed. The included carrying case is a nice touch and helps to keep the filter safe and protected when not in use.

Overall, I am extremely satisfied with my purchase of the K&F Concept 62mm ND4-64 (2-6 Stops) ND Lens Filter Variable & CPL Polarizers Filter 2-in-1 and would highly recommend it to other photographers. It's a high-quality and versatile addition to any camera setup.

The K&F Concept Magnetic Variable ND Filter offers a convenient way to control light for smartphone photography. While it has some strengths, it also comes with a few limitations.

Key Features:

Magnetic Convenience: The magnetic attachment system makes it quick and easy to apply and remove the filter.
Variable ND Range: The ND2-32 filter provides a decent range of light reduction for various shooting conditions.
Phone Compatibility: Designed to work with popular iPhone models, offering versatility for smartphone photographers.
Room for Improvement:

Image Quality Concerns: Some users have reported noticeable image quality issues, such as color shifts or vignetting, especially at the filter's extremes.
Filter Thickness: The filter adds bulk to your phone setup, which can be inconvenient for some users.

Overall:

The K&F Concept Magnetic Variable ND Filter is a decent option for smartphone photographers looking to experiment with light control. While the magnetic system is convenient, the potential image quality issues and added bulk prevent it from earning a full five-star rating. If you're willing to accept these limitations, the filter can be a useful tool for your mobile photography kit.

As an avid photographer constantly exploring new techniques and tools to enhance my craft, I recently invested in the K&F Concept 82mm Variable ND Filter, and I'm excited to share my experience with fellow photography enthusiasts. This filter has quickly become an indispensable part of my kit, offering unparalleled versatility and convenience for capturing stunning images in a variety of lighting conditions. The variable ND feature allows me to easily adjust the amount of light entering my lens, giving me greater control over exposure and enabling creative effects such as long exposures and shallow depth of field, even in bright sunlight. I was impressed by the filter's build quality – crafted from high-quality materials, it feels robust and durable, yet remains lightweight and easy to handle. Additionally, the slim design minimizes vignetting and maintains image sharpness, ensuring optimal performance with no compromises. Whether shooting landscapes, portraits, or action shots, the K&F Concept Variable ND Filter delivers consistently exceptional results, making it a must-have accessory for photographers seeking maximum flexibility and image quality. I wholeheartedly recommend this filter to photographers of all levels looking to elevate their work and expand their creative possibilities.

I bought the K&F Concept Variable ND Filter Neutral Density ND2-ND400 (9 apertures) with rotating ring to be able to use a fast ND with different densities. The packaging is very well made, solid and space-saving packaging. The glass filter is light and the density increase / decrease ring is liquid. It does not have a limit switch block.

The "K&F Concept Nano-X ND Filter 77mm" comes in elegant packaging, which is easy to open and you can carefully remove the filter. The bag that goes with it is well made, everything looks very classy and you can expect that for the price. The filter itself is of very high quality and you can see all the key figures directly. Furthermore, it has two brass noses, which can be easily adjusted. Here you always have a good feeling and you overshoot (turns too fast) or too slow, but you always have the right feeling when adjusting. The resistance here is just fantastic. The image that can be conjured up from the filter is simply overwhelming and is worth its price. Here it makes no difference whether you have sun in the picture or are completely blinded,

This K&F Concept graduated ND filter is a great addition to any sunset or sunrise landscape filter collection. For the price, the filter feels well made and has smooth threads and fits perfectly on my Sony lenses with or without a pre-filter. I haven't had any issues with threads as some have reported. The filter has a very smooth gradation with a smooth pivoting mechanism to align the color gradient as desired.

I received this K&F Concept 58mm ND8 Lens Filter (3 f-stops), Fixed ND Filter with Double Sided HD 18 Layers Multilayer, Ultra Thin Optical Mount, Nano-X Series for Lensless Camera Lens in the Amazon wine program. Generate reviews on new products to be heard on Amazon. ND filters are designed to take long exposures and not overexpose photos or change colors. The filter also reduces the intensity of all wavelengths of light without changing the hue of the color rendering. It filters to reduce the amount of light entering the lens. This allows us to choose combinations of aperture, exposure time and sensor sensitivity that would otherwise produce overexposed images. There are difficult ND filters to control the amount of light entering the camera, that's three stops. This K&F Concept ND8 filter is well made and works well. I've only filmed it once so far, but it was very cool. These are a must have for any Phoargophère amateur or professional. I can highly recommend.

The K&F Concept ND Filter does not have a stop, it will continue to spin all the way around. Though it does spin freely, taking the camer in and out of a bag/case may change the filter intensity. Otherwise it allows for much lower f stop. I use this while filming outdoor shots.
