   i was impressed by the build quality of this filter. It has a nice heft to it without feeling heavy and I like that it comes with a rubber cap that can be left on it if you want to leave the filter on the lens when traveling. Otherwise, it comes with a plastic snap case that works well for keeping it protected.The side of the filter has markings to show the ND strength. While they don’t click into place at any given strength, the filter turns smoothly but with enough effort required that you don’t need to worry about accidentally rotating it out of place once set. The marking are easy to read and align with the arrow.I did notice a couple things about using this filter. First, it adds a slight warm cast to the image. It’s fairly subtle, but you can see just a hint of a warmer, yellower tint to all the test pictures with the filter in place. The ND strength markings seem accurate, as I adjusted my shutter speed by a stop each time I changed the ND a stop and the exposure seems consistent throughout the range.The second artifact I noticed is due to the way variable ND filters function, as they filter out polarized light. You may notice that without the ND filter and at the strength of ND 2, the greens in the trees and plants is a darker green. As the ND strength increases, the plants take on a brighter, more neon green look as the reflected, polarized light off the plants gets filtered differently. This is not something you’d see from single strength ND filters, as they don’t use polarizing technology to achieve their filtration. It’s not a major deal, but something to be aware of.Overall, this is a well built filter that has a tiny bit of color shift and exhibits some polarization artifacts, but nothing that isn’t out of the ordinary for most variable ND filters and nothing that would cause me to hesitate to use this on shoots. I like the feel to the rotating polarization ring, as it’s well dampened and feels high quality and has easy to read markings. The 1-5 stops of range is a bit small, falling short of many other offerings from both K&F Concept’s own lineups as well as many competitors. K&F Concept offers many other variable ND filters under a range of model lineups, but I’m not exactly clear on the differentiation between their different lines. But when it comes to this filter, while not absolutely perfect, it performs very well and will find a place in my kit now.

   Allow me to start by saying.. I’m an old school photographer. My first encounters with ‘real’ cameras, was an old Hasselblad medium format camera, with attached billows. Sure, I never actually took real photos with it (price was too much), but it’s what I grew up with, pretending to be a photographer.It wasn’t long before I ‘graduated’ to 35mm cameras, 110 cameras, and (insert exhausted sigh), disc cameras.I’ve long since moved into the digital realm, sure.. but there have been always a few throwbacks that I still use, even though there are supposedly better solutions out there… force of habit, I suppose.One such thing that I have refused to migrate towards, has been variable Neutral density filters, instead sticking with the well established static ND filters. (no movement, no variance)One of the biggest problems with using the older tech, is that you have to carry around multiple ND filters with you, OR constantly adjust your exposure to get the perfect photo exposure that works with the image you’re capturing.Another big issue, is when you’re getting images, later in the day, when your natural light is rapidly diminishing. Not a big issue if you’re talking 20-30 second exposures, sure.. but once you get into extended minutes, changing light can really alter a great image, into a greatly underexposed one.That brings me to this, a variable ND filter… I wish I would have taken the time to migrate to one of these sooner. No more do I have to carry around multiple ND filters (Even though my OCD still requires it.. *chuckling*)A simple twist of the filter changes the stops that you are operating under. How many stops? Well, that’s the part that may be a bit confusing to the average user… 2-32 isn’t actually 30 stops.. it’s just a simple 5 stops. (2, 4, 8, 16, 32)That said, if you’re wanting to compensate for the ND, remember to adjust your shutter speed, iso, or aperture to offset it. (Some would argue you can also use EV, too, but I tend to recommend that only for in camera mid-level changes)From the dozens of images I’ve taken with this variable filter in place, color shift is minimal (there appears to be an ever so slight warm color shift… and when I say slight, I mean if you’re not checking your white balance, you likely won’t notice it)Another thing to point out for those users that may be using a variable aperture (I tend to use a Sigma 24-70mm f2.8 ART lens as my go to, but I also have tested this on a Tamron f2-2.8 35-150) is that you will need to keep in mind, the f-stop changes as you adjust the zoom level. So you will also want to adjust your ND, accordingly. (Or, lock in at your highest possible static F-stop, in the case of the 35-150, that would be an f2.8)I’m quite pleased with this variable filter, and while it won’t get rid of some of the 10-30 stop filters, it DOES have the potential to remove some filters from my kit… even if I don’t have the confidence in myself, yet, to do so… hey, old habits, as I said before.The price to performance level of this filter is great, and K&F’s equipment always seems to perform as well, or better than many of my other equipment. Hats off to them.

   I shoot a LOT of outdoor landscapes. But when the sun is extremely bright and you want to take a longer exposure while maintaining control over the depth of field, the K&F Concept 82mm Variable ND2-32 Lens Filter is the perfect tool. It allows you to take full control of the scene by dialing in the perfect amount of neutral density.I shoot a lot of HDR (High Dynamic Range) images and even in the worst lighting situations I am able capture very nice images with this professional quality filter.Along with my AMEX card, I never leave home without it!
