Finally after 3 products from K&F I found what I was after, the 1st set, screw on one's are good but too fiddly for me, 2nd, square set again great but can't fit lens cap & not enough filters in the range, & finally this set, absolutely fantastic, everything I was wanting, more ND filters will be added to the range, magnet is good, filters have next no colour cast, the CPL is great to use, quick & easy changes with no fuss, compare these with more expensive brands & you will wonder why you spent all that money, these do everything...if not a little better than a few well known products out there, I am so pleased with these I am going to feature them in my YouTube channel.... Moto Tripper UK.

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 :)

I bought this filter for the Sony lens. The filter delivers what it promises and for this good price. I can't find any defects, be it blurring or a black “X”. Clear recommendation.

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!

Filters do whats advertised.

I shoot in various elements and destinations where lighting is different and filters are needed for optimal results. I have been using the traditional screw on filters but I find it time consuming especially how it needs to be aligned perfectly on your lens, taking up to a few minutes for each one when I could miss the opportunity of my shot. I find this K&F filter set to be a great choice for me. I am no professional by any means and take photos for fun with my Nikon d850 and these filters have worked great for me. The magnetic adapter ring is easy to screw on the lens and the lenses stick to it well. These lenses work great in the rain and are not only waterproof but the water beads off of them. I have not had any issue of fogging between the lens and filter.

The come packaged nice in a hard case, each in its own slot. I find this to be a great value for all of the different lenses offered in this set and I am extremely happy with them.

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 am very satisfied!
