I am very pleased with this system and the quality of the filter lenses. It is wonderful for very quick changing of filters. Unfortunately I accidentally lost the ND filter the first time I went out and did not realise it until I was back home. My friend had zipped the bag they come in, and I, thinking it was still open and more concentrated on trying the one on the camera. unzipped it. So during my wanderings, the ND fell out. I did eventually manage to replace it, and received a magnetic lens protective cover as part of the order. I am made up now. I do recommend this system and it has the filters that I use, perfect.

I own quite a few K&F Concept Products. They provide quality products without the hefty price tag we're used to see in the photography world.

Let's talk about the filters individually first. All 3 filters are of top quality, at least on this price point/tier, as we're used to get from K&F Concept products:

-The CPL Filter has no color shifting and performs as expected.
-Same with the ND1000, although i don't use 10-stop filters that often (my most used filter is a VND Nano from K&F Concept) during my test it worked well, no cross present, even while using step-up rings.
-The UV Filter has no color shifting and the main purpose these days of the UV filter is to protect the lens surface, BUT, It is where this VERY MINOR issue this kit has: The magnetic ring holder.

The magnetic ring holder works great with the ND and the CPL, just not as good with the UV Filter, but it is not by ANY MEANS bad or i'd call it unsecure, at least not on the 82mm filter size version, your mileage may vary depending on the kit size you got as the magnetic surface may be different for your version, just the grip doesn't feel as tight as it does with the other two filters and there is a TINY bit of play, but not enough to warrant losing a star over it, i mean if you shake the camera at full strength you may drop it, but on regular usage i do not see it just falling off the ring holder.

As the sum of all parts i'd say this was almost perfect. This kit complements my VND ND2-400 and includes everything i need to cover all my filters along my step-up rings. The UV filter thing doesn't make it lose a star, but maybe half, so i'd say 4.5 but since there's no option for that if i had to decided between 4 or 5 stars, i'll go with 5.

Bonjour,

Étant tombé sous le charme de l'effet ND1000 sur les photos de paysages, je me suis décidé à en acheter un.

rappel : prendre une photo avec une priorité à l'ouverture (mode AV) et une certaine ouverture de diaphragme et récupérer le temps d'ouverture (sur ma photo : 1/4 de seconde = 250ms).

Mettre l'objectif en mise au point manuelle et placer le filtre ND1000 en évitant de changer la mise au point.

Multiplier par 1000 le temps d'ouverture précédent. Dans mon exemple 0.250s x1000 = 250s (4min10)

Mettre le reflex en mode exposition manuelle puis en mode BULB afin de télécommander le temps d'ouverture. (dans mon cas, j'utilise mon smartphone qui a un port infrarouge).

On constate après 4m10s que la photo (avec filtre) est identique en couleur et en luminosité que celle prise en 1/4 de seconde sans filtre.

Ce filtre est donc bien calibré.

Important : l'utilisation d'un pied est fortement recommandé pour éviter tout flou de bouger.

En conclusion, je recommande ce produit et j'ai hâte de pouvoir aller prendre des photso de paysages avec ce filtre.

Bonne journée.

The filter works well and does what it should. Quality and price are right. Who wants to know more should watch my video :)

Filters do whats advertised.

For two years this filter has been my loyal companion on every photo tour. The processing is absolutely great and together with the really stable storage box an absolute must-have!

Disappointed by a previous ND, I bought this ND1000 and I am satisfied with it. The screwing and unscrewing is without constraint and the rendering is very correct, no distortion or radiation, and the colors are preserved.

I needed a more travel friendly set of filters to take with me on my hikes that would be too cumbersome to use my square ones. Having these filters in it's own soft pouch was perfect and it didn't take up much room in my camera cube. The magnets were strong as they held on while I was setting up my composition - sometimes in the rain and while on uneven ground.

UPDATE 10/26/21: After over a month, I've already lost a CPL filter. Make sure the filter is flush in either the UV adapter or adapter ring. I was busily setting up my camera on a cliffside when I accidentally bumped my tripod and the CPL filter fell off.

An ND1000 filter is particularly interesting for landscape photography. This can be used to soften waterfalls, for example. I have used this filter several times on vacation for this purpose and have not been disappointed. I have attached an example photo. (River with lateral water drainage) Image quality is consistent throughout the shot. The darkening is also uniform. Have fun taking pictures!

Molto comodi con il meccanismo magnetico. Più volte quelli a vite mi sono rimasti incastrati nelle lenti. Con il ring magnetico sono veloci da cambiare e usare. Quelli di 82mm sono compatibili con il sistema Kase che offre più scelta di filtri ma a un prezzo più alto. Io ho un mix ora dei due brand e mi trovo bene. Per qualità prezzo i filtri K&F si posizione in un ottimo posto. Io li raccomando vivamente
