Great look for the price.

Seems a fair price, sharp images and not very noticable colour shift

Very good filter for a great price.Could not be happier with the purchase

I have been taking photographs since the mid 1970s and over the years have gone through my fair share of filters, square, round and even homemade.This K&F filter comes well packaged in a sturdy plastic box which a foam insert designed to securely hold the filter whilst being transported. The insert has recessed finger holes for very easy removal of the filter even with cold fingers. On picking up the filter the first thing you notice is how sturdy it is and how velvety smooth the movement when you twist the outer ring. I have purchased lower-priced filters before and sometimes been very disappointed in the mechanical construction but not this time as it is on a par with many more expensive filters in my collection.I purchased this to use on my Nikon lenses when shooting video. My normal choice of filter is the square system but at present for video use these screw-in ND faders are by far the best option for my money. One of the first acid tests for any filter is how well it attaches to the front of the lens and this one did not disappoint. Straight on, first time with no fuss or fumble.The filter rim sits proud on a Nikkor 24-70 f2.8 making the outer ring very easy to grip when adjusting the strength of the ND filter. This is a relatively slimline filter and as with other slimline filters I have used the lens cap does not feel very secure attached to the front but this is not an issue with this type of lens as I only have it attached whilst I’m actually using the camera.Whilst I have not had the chance yet to try the filter in all conditions my early conclusions are very positive. Physically using the filter is very pleasant because of the smoothness of operation and there are handy markings around the rim of the filter showing maximum and minimum positions.On a dull day like today, shooting with a Neutral picture style I found the images taken with the filter lacked just a little contrast compared to those with no filter. I doubt that it would be as noticeable on a bright, sunny day (when to be fair an ND fader is more likely to be needed) but in the event it was not a major issue as I simply tweaked the contrast up a notch or two and created a custom picture style which worked a treat. As soon as we do get a bright, sunny day I will test the filters again and if my assumption regarding contrast proves wrong I will post an update below. However, with a 1,500 mile wide storm due to batter the Uk over the weekend don’t hold your breath!I have other K&F products in my kit bag, including lens adapters, and would not hesitate to purchase this brand in the future. On my personal experience to date they are well constructed and represent very good value for money.This filter represents incredible value for money and the small niggle with reduced contrast in dull conditions does not give me a reason to reduce the star rating. Had I paid around the £100 mark for the filter then all other things being equal I would certainly be dropping one star but at this price point that is just being curmudgeonly.Please note that whilst I have reviewed the 77mm version here I have also purchased a 67mm version too for use with a Samyang 12mm lens on a Fuji X-T10.

High optical quality filter, just like all their other products. I highly recommend this to all landscape photographers or anyone interested in experimenting with day long exposure as this is a convenient single piece which is affordable as well. It is easy to slide and the gradient change is noticeable yet subtle. It does not leave a colour cast nor does it affect optical quality. The filter may not be the thinnest but it does not leave any colour cast even with wideangle lenses. The luxorious little case and box that it comes in leaves little more to be desired for. This is indeed a top product for its price. I will be purchasing more of their products and will be recommending this to everyone at my workshop. This single piece saves you the trouble of having to keep changing filters which may cause damage or scratch your other filters or even worse, missing the perfect light of the moment.
