K&F CONCEPT 77mm Variable ND4-64 Lens Filter & Polarizing Effect 2-in-1

First off, the quality of this thing is superb. Even the packaging is fantastic. It also doesn’t cost that much for what you get. You get a great variable nd filter as well as a polarizer. I will say though the polarizer is an okay feature so if you’re looking for a top of the line polarizer, I would suggest something else. It fits perfect no problems and I have experienced little to no vignetting. I bought this because I needed something to make videos darker as my shutter and iso can’t be changed for video purposes. It does just that and it works wonders at its job. It also helps with avoiding fingerprints if you’re prone to accidentally touching the front of the lens.

One of my favorite fillers. Highly recommend!

The ability to adjust the stops with 1 lens makes all the difference when the sun is going down and you want to catch that perfect shot. On the brightest time of day it cuts the glare, gives you crystal blues and greens, perfect for ocean shots. It comes in a nice case with a ribbon pull to bring the lens up to grab and not get finger prints on it. Easy to put on and take off, works with standard lens cover.

I recently took this filter to the Pacific Northwest and it got the job done. I was able to easily use the filter across multiple focal lengths (using step up rings). There was some deep vignette at 5 and 6 stops, but there was never a reason for me to shoot at those stops. I'm sure that I will eventually get a more expensive ND filter, the value and performance of this filter is perfect. This is the kind of filter that stays in your camera bag and becomes a much needed tool when you are not able to control the light around you.

Well made and so versatile!! A little tight, but it seems to be loosening up with use.

The filter works ok. In photo mode it suffers from the pola X darkening on the image. My biggest complaint would be, it doesn’t allow me to put the lens cap on. If that is a known issue this should have its own lens cap that works with it. I’m basically forced to either remove this filter a million times, or just run around with the filter exposed to the elements.

So I own the Polar Pro Peter McKinnon edition VND filters, both the 2-5 and the 6-9 stop and I see no difference with this filter. It’s high quality, I prefer the bag this VND filter comes with, it’s clean and smart. This filter punches well above its weight class and it is a must for those cinematic shots in the bright sunny conditions. Highly recommend. And a word of advice. Buy the largest size and then buy some step up rings. Much easier to buy another step up ring in the future for a bigger or smaller lens than it is to buy another VND filter because the one you bought was too small for a future larger lens

Gran calidad sin ese efecto de la X

Le filtre K&F Concept 58mm 2-en-1 (Polarisant + ND4-64 variable) est rapidement devenu un indispensable dans mon équipement photo. Sa conception intelligente permet de bénéficier à la fois d’un filtre polarisant circulaire et d’un filtre ND variable (2 à 6 stops) sans avoir à multiplier les accessoires sur l’objectif. C’est un vrai gain de place et de praticité, surtout en déplacement. La qualité de fabrication est au rendez-vous : le verre optique japonais avec ses 28 couches de nano-revêtement offre une excellente résistance aux rayures, à l’eau et à la poussière. Les bagues de réglage sont fluides et précises, ce qui permet d’ajuster facilement la densité ND ou l’effet polarisant selon les besoins de la prise de vue. En utilisation, le filtre ND variable est parfait pour les poses longues, la gestion de la lumière en plein jour ou la vidéo, tandis que la fonction polarisante permet de sublimer les couleurs, d’augmenter le contraste et de supprimer efficacement les reflets sur l’eau ou les surfaces vitrées. À noter, il n’y a pas d’effet de croix noire (X-cross), même avec des focales grand angle, ce qui est un vrai plus par rapport à d’autres modèles. Le rendu des images est fidèle, sans dominante de couleur ni perte de netteté, ce qui garantit une excellente qualité finale. Le filtre est livré avec un étui de protection solide, très pratique pour le transport et le rangement. En résumé, ce filtre K&F Concept 2-en-1 est un excellent choix pour tous les photographes et vidéastes qui recherchent polyvalence, qualité et simplicité d’utilisation. Il offre un rapport qualité/prix remarquable et répond parfaitement aux attentes, que ce soit pour la photo de paysage, de voyage ou la création vidéo. Je le recommande sans hésiter !

L'emballage au top, la pochette et le filtre sont bien protéger. Arrivé avant le jour prévu. Je suis contente, cette marque et vraiment une belle qualité

Sconsiglio vivamente l'acquisto in quanto non è assolutamente vero che non si verifica la X al centro dell'inquadratura come menzionato! Qualita/prezzo voto: 0 (potrebbe costare al massimo 10,00€ (rubate) per la sua qualità). Inoltre segnalo un corriere inadeguato alla consegna all'articolo in quanto partecipante al lancio del giavellotto!

Probado en un Sigma 10-18 mm y el rendimiento ha sido excelente. El K&F Concept Nano-Xcel 67 mm combina CPL + ND variable (ND4-64) en un solo filtro y funciona de maravilla: no aparece el efecto X ni siquiera en la focal más angular. La calidad óptica es muy buena, sin pérdida de nitidez ni viñeteo, y el anillo gira suave y con precisión. Muy práctico para paisaje y vídeo. Gran construcción, versátil y con una relación calidad-precio sobresaliente. Totalmente recomendable.

I've been using the K&F Concept VND + CPL (4–64) filter for video, and it's been a great addition to my kit. The image quality stays sharp, the colours remain natural, and being able to adjust the exposure without changing camera settings is really convenient. The built-in CPL is a nice bonus for reducing reflections on cars and glass. It feels well made and has been reliable on every shoot so far. Great value for the price. Pairs perfectly with my camera setup
