For the price an absolute top filter does what it should

I found this filter excellent when properly screwed on to my lens, vignetting was visable when not properly fitted. It is quite shallow which also helps here.
Shots displayed are taken with Nikon Z6 & 14-30mm S line lens I had to stop down to F10 for 20secs & F13 20secs both shots ISO 50 to avoid blowing out the sun, shadows recovered in post processing.
The filter was very easily wiped clean after being splashed by a wave, I think the coating definitely helped here.

I am quite pleased with the product its defintely much better than my old 72mm

Great for the price. Do what i need

The filter is really good, it seems to be a real 10 stop filter (some ND1000 are only 8-9 stops, which makes shutterspeed calculations hard), it is reducing light in both Visible and Infrared light (has been tested on a full spectrum camera used for Infrared Photography), so you will not have a nasty discolouration in the sky as with other ND filters, but you will get a slight blue colour cast, nothing that can not be fixed in post process with the white balance tool, but I highly recommend doing a white balance setting with the filter on to get accurate colours, especially if you are shooting in JPG. I did not see any reduction in detail (see the 100% or 1:1 crop). It easily screwed on my lens and step up rings as well. It has a nice grippy area which I find giving a much better grip than other filters. One thing I'd like to mention is the case it's coming with has a nice locking mechanism and also two carve outs to be able to easily remove the filter from it's case, actually it's one of the best cases I've seen, beating the nice metallic cases from Gobe, which does not close well with larger filters.
If colour cast is a critical issue for you then this filter might disappoint you with it's blue cast, in that case I recommend Haida's NanoPRO ND1000, which I unfortantely lost, but that has virtually no colour cast at all, but nearly triple the price.

I am very satisfied with the ND filter. Can't see any color cast and the price is right too.

After reading and looking at a number of tests, in which the filter mostly performed better than expected for monitoring the testers, I bought it. The filter fulfills its purpose at least 99% and delivers a top result on my Canon 80D. I am glad I bought this one and would buy a filter from K & f again at any time.

I tried the ND1000 58mm on my Nikkor 50mm 1: 1.8G. It was really very bright and you can see what came out of nd filter in the photos. :) I can only recommend.

Ok seriously - anyone who knows or deals with ND filters knows what this little miracle is for ... Long exposure in pure sun and in the middle of the day. Quality is great - can be screwed on perfectly and fits perfectly! A suitable protective box is included in the scope of delivery so that the filter can be carried around undamaged. The results are great! Clear buy recommendation

The price point of the ND1000 filter is very reasonable considering the quality of this item. It's very slim and causes no vignetting on my Canon 16-35 L at 16mm. The colours are faithful and it allows for a decent length of shot in daylight.

Don't see why I should spend more money for a 10 stopper of any of the big brands when this one does the job just fine! No unwanted tints or reduction in image quality that I can see. Any tints or hues are added in post production. Highly recommend!
