K&F CONCEPT 77mm Variable ND Filter ND4-64 & CPL Polarising | No Black Cross Waterproof Multi-Coated Adjustable Neutral Density Precise Light Reduction Smooth Rotation Nano-X Series FB703

I got this to go with a 18mm-400mm lens only filter l will need

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

I have a good set of NISI filters, but I find that I'm using this much more often. It is so much easier to use when you are on the move. I was on a photography holiday in the West of Ireland lately and just kept this filter on my Z6 Nikon camera. The polariser took out the washed out colour of the sunny sky and sea. I used the ND filter for sunsets, as I prefer not to have the full sun in the shot to avoid glare, but still get the lovely colour of the sky. The filter leaves no colour cast. I have also found the filter very good at darkening waterfalls sufficiently to get that nice smooth water effect.

Using the 77mm filter - from a videographer's perspective, here are my thoughts: Pros: • Adjust exposure on the fly - I can keep ISO, F-Stop, and shutter speed all locked while my subject goes from direct sunlight and into the shade by sliding the orange adjustor. • I can adjust my ND strength while keeping my CPL in position. • Build quality feels great. • Great ND range for outdoors and sunny weather. • Works great with step-up adapters so I can use it on my smaller lenses. Cons: • I have noticed some vignetting in certain lighting situations. • Adjusting the ND strength sometimes pulls and rotates the CPL filter. You can physically see the CPL rim rotating as you push the ND slider. Can be avoided by holding onto the rim while adjusting the orange slider. Would I recommend this product? Yes I would. I bought this for the free moving ND slider which some other VND filters do not have. The ability to freely adjust stops in sunny conditions makes this product vital to my videography work.

Filter is easy to adjust the level of light entering the camera. Image quality is great using the filter. Definitely recommend. Fitted to Canon 5DSR - Canon 16-35mm F2.8 iii

I bought the 49mm for its pocketable size so could always have it in my bag. Sadly as you set the CPL the ND moves slightly, then once set you move the ND ring and the CPL part moves, sometimes only slightly, but enough to throw off your settings. You have to hold one ring in place while moving the other. This works while on a tripod, but hand held I found it really frustrating and hard to juggle, making it not worth the hassle. On a positive note it hard stops and I didn't get the dreaded X and I found the colour reproduction very true to life and as far as the build feel and glass goes, its 5/5, but the dual implementation didn't work for me, so returned.

Firstly this is a pretty high quality piece of manufacturing, the frame, glass and smoothness of the rotation rings are great. It was well packaged and the little leather case it comes with is awesome. My gripe with this iswhen rotating the VND you end up also moving the polariser ring...this is more annoying when you dont want to engage the polarisation effect. This means you need to use both hands, one to hold the inner ring and the other to adjust the ND, fine if you are on a tripod but if you are hand held with a heavy DSLR and wanting to adjust quickly its not easy to manage. Most people i would imagine use this on on a tripod and probably wont find this annoying, but for thise street photography days in harsh glary lights i can see this causing a few messed up / unexpected lens intervention.

I bought two of these for my lenses (different ones) and while they are presented nicely, with luxury packaging and they are heavy and solid, the lens cap don't fit them. Their diameter is teeny tiny bit larger than should be and the caps ALMOST fit but very loosely and with movement they fall off. You can have either a lens cap or a filter on your lens, not both. This is very frustrating because the filter is opened to scratching and damaging while handling a camera between shooting. Unless, of course, you have the all time and patience in the world to remove the filter and put a cap on and then replace one with another each time you want to shoot or in between the scenes. I use Nikon D810 and good lenses and I can't believe that this is the way these filters are designed. I will try managing this but there is a chance I will go back to my old Hoya filters. They are also expensive (some even more) but at least I can put a cap on them so they don't get scratched. TERRIBLE fault! How can they NOT accept the caps over them???

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.

Tolles Zubehör! Anfangs war ich skeptisch ob ich den Filter überhaupt benötige, aber aufgrund dessen, dass jetzt Frühling/Sommerzeit anfängt und die Lichtverhältnisse zum fotografieren eher schlechter werden, hab ich dem Filter eine Chance gegeben. Lieferung & Lieferumfang: Schnell wie immer, im Lieferumfang ist der Filter selbst als auch eine nette Kunstleder Tasche zum aufbewahren vorhanden. Was evtl noch super wäre, wäre ein kleines Mikrofasertuch, aber es geht auch ohne Filterqualität: Cpl als auch einstellbare ND ist wirklich super, es sind keine Bildverschlechterungen bemerkbar und der Filter selbst ist stabil gebaut. Zusätzlich bietet er auch Schutz für das Objektiv Fotoergebnisse: Erstes Foto Aufnahme bei hellichtem Tag. Keine Überbelichtung und keine Probleme mit Iso. Zweites Foto die darauffolgende leichte Nachbearbeitung und ein perfektes Ergebnis. Man sollte allerdings mit Auto-Iso aufpassen, aber ansonsten rundum zufrieden. Nicht mein erstes aber auch nicht mein letztes K&F Produkt Fazit: eindeutig 5* von mir und zu dem Preis (ca. 68€) ein Top Produkt
