Flitro ND1000 Fixo (10 stops), Nano-X, diâmetro 58mm

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.For the price the K&F Concept ND1000 is unbeatable. It has just a very very slight blue colour cast, great IR filtering, true 10 stops and no reduction in picture quality. If you are on a budget and looking for an ND1000, look no further.

I really like the filter

A decent ND1000 82mm filter provided with an excellent carry case.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

Recently bought this ND1000 filter. On unboxing found the build and finish of the product to be very good. It also comes with a very robust travel case, to protect and keep the filter clean.I have used the filter a couple of times (see attached photo), whilst I am not completely happy with the photo, I believe this is down to me and camera settings. I am completely happy with the filter.A recommended buy

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.
