When photography became more than a hobby for me, I started collecting various accessories to make my camera package more complete. One of the elements I found to be essential was a good set of filters for my camera. I started collecting UV filters of various brands, but when it came to an ND filter, I was a little pickier. First of all, I wanted one that was budget-friendly as well as well-made. I finally found what I was looking for in the 77mm ND1000 Filter from K&F Concept.This filter is available in a variety of sizes from 58mm-82mm. The ND1000 is made with premium Japan Optics glass and an aluminum alloy frame. It’s slim, lightweight and the extra tough frame ensures long-term durability and prevents jamming. The filter features a top level of transmittance and does not have color cast. The 18-layer multi-resistant coating reduces lens flare and ghosting while also making the filter scratch resistant, water repellant, and oil and dust resistant. The multi-coating process also makes it possible for users to achieve super slow shutter speeds in daylight to render moving objects invisible. Because it’s an ND1000 filter, you have the option to reduce the amount of light in a photo by 10 and effectively reduce light reflections while improving the overall image quality.The filter arrived in a very secure, hard plastic case. It was easy to open, but keeps the filter safe from environmental factors when it’s not in use. It stores easily alongside my camera in my camera backpack. The general purpose of this type of filter is to provide users with a strong neutral density (ND) filter which reduces the amount of light hitting the camera’s sensor by about 1000 times. The ND1000 is an extreme version of the neutral density filter as many of them are typically only 3-stops in strength.I wanted this filter specifically for outdoor, long-exposure photography. I thought this filter would help me to have a wider variety of shots when using the same photography equipment that I normally do. My favorite all-purpose lens is the Canon EF 24-105mm. This is a 77mm lens and so I selected the 77mm size filter from K&F Concept. The filter fits perfectly on the 24-105mm lens I mentioned before. I didn’t have any issues with it fitting or screwing into place. This has been an issue for me in the past with some other filters.I tested the filter in a few different ways. First, I held the filter up to the lens without screwing it onto the lens. This showed the difference between the image with the filter and the image with the filter. With this type of test, you can clearly see a correctly exposed image and one that is darkened quite a bit with showing only the ‘hot’ spots of light in the photo. After taking a few shots with the filter installed on my camera, I noticed that there were no edge vignetting issues at all. The glass seems to be of high quality since I didn’t notice any ghosting issues either.The ND1000 Filter from K&F Concept is a very nice option for a budget-friendly, high-quality piece of glass. It’s been very useful for me and a great addition to my camera kit. If you are looking for an ND1001 filter, I can recommend this one from K&F Concept as opposed to one from another manufacturer that might cost an arm and a leg.
