K&F CONCEPT 77mm Variable ND Lens Filter ND3-ND1000 (1.5-10 Stops) Putter Adjustable HD Neutral Density Filter with 28 Multi-Layer Coatings for Camera Lens (Nano-X Series)

Ah, the variable ND filter from K&F Concept—strong in the ways of the Force, it is. Crafted with the precision of a lightsaber duel, its Japanese AGC optical glass, multi-coated with 28 layers, shields against the dark side of glare and reflections. Clarity, it bestows. The putter adjustable design, clever it is. Like a Jedi adjusting his focus in battle, one may fine-tune the stops with ease, rotating the frame with the grace of a master wielding his blade. From ND3 to ND1000, versatility this filter grants, useful across many landscapes and scenarios. Waterproof and scratch-resistant, it is. Strong against the elements, it stands. Oil-proof and hydrophobic, like a Jedi’s robes repelling the chaos of the galaxy, this filter remains resilient through the trials of adventure. Vignetting, it does not—unless the wrong lens thou useth! A slight dark "X" may appear, but turn the frame, and balance in the Force is restored. Turns water into smooth, wispy trails even in bright light, this filter does. Like the flowing energy of the Force, movement transforms into an ethereal dream. But heed this warning, young Padawan—manual mode, you must use. Settings to Master the Force of the Filter: Shutter Speed: Slow, you must make it. 1/4s to 30s, depending on water’s movement and light. The longer the exposure, the smoother the trails. Aperture: f/8 to f/16 is wise, for clarity and depth, it ensures. But adjust, you may, depending on conditions. ISO: Keep it low—100 or 200, lest noise disturb the balance of your image. Focus: Manual focus, use. For sharpness, a Jedi does not rely on the camera alone. Also works great at night, it does! For streaking lights as they pass by, perfect it is. Speeder bikes on Endor, landspeeders on Tatooine, or city streets in Coruscant—long exposures, you must use. Night Photography Settings for Light Streaks: Shutter Speed: 10s to 30s, for motion trails that flow like the Force. Aperture: f/8 to f/11, for balance between light intake and sharpness. ISO: 100-400, depending on ambient light. Too high, and noise will corrupt the image. Tripod: Essential, it is. A Jedi’s hands, steady they may be, but long exposure requires stillness beyond mortal ability. Compatible with all 77mm lenses, this filter is, but beware—an 82mm lens cap, thou wilt require. Such knowledge, crucial it is, lest disappointment consume thee. Verdict: In the ways of photography, a Jedi must always choose his tools wisely. Strong with the Force, this filter is. Recommended, it comes highly.

I needed a variable ND last minute that fit 67mm thread, and this was available for same day delivery. So I pulled the trigger. Normally, I buy high-quality filters like B+W, Breakthrough, Haida, or Heliopan. So I was apprehensive about this one, especially being a variable ND. But I was thoroughly surprised. First, I LOVE the tab. It makes it so much easier and nicer to adjust the strength than trying to grip the edges of the ring. Second, I didn't notice any issues with color shift. Maybe if I shot side-by-side with the filter and without I would notice some, but it's nothing major. Even the best variable NDs have some color shift. I didn't use it at its strongest setting so I'm not sure about the dreaded "X" pattern, but I always avoid the strong end with variable NDs. I only wish it had hard stops at each end. I'm not sure why that isn't standard for every company. Attached is a photo taken with the filter on an OM System OM-1 + Panasonic Leica 12-60/2.8-4. ISO 200, f/6.3, 15 second exposure.

Works well. Easy to use for solar shots. No problems getting stuck on my lens.

I have Urth 77mm 64-1000 ND and while I am happy with its performance, it cannot go below 64, which is quite dark. I wanted a variable ND which start from a lower number and goes all the way up to 1000, so that I can shoot full open aperture in RF 50mm F1.2 all day and evening without taking off the filter. This K&N filter fits my bill. It is perfect optically as there is no color shift, vignette or dreaded X pattern at the darker end. However it lacks two physical design limitations: 1) The filter does not stops at the lowest and highest ND limits like the Urth can. I need to take the camera off from my eye to set the filter darkness, a minor hassle 2) The small tab on the filter rim prevents fitting any lens hood after the filter is put on. Overall, this is a great ND filter for any photographer or filmmaker who wants to shoot full open aperture or slow shutter speed photo. I am very happy for this purchase, it will not collect dust like so many other camera accessories I have purchased in past.

muy bueno

First time using K&F products. And I was not disappointed at all in the packaging and craftsmanahip of the item. Very nicely made and feels solid. Adjustment moves with slight resistance but feels just right. There are no solid stops but the stops which wouks be nice. But then the price would no dount reflect that. The stops are marked with dots which also works.

Unfortunately I cannot recommend this filter. I purchased it specifically for the variablability. When I used it at the 10-stop it produced a heavy dark blue cast in section of the frame. I am most disappointed in this filter.

This definitely worked well for sunny settings so I was able to take long exposure/low shutter speed photos without worrying about them being too bright or a completely white photo. The materials are high quality and I like the packaging it came in. Definitely recommend especially if you’re a beginner photographer like me.

Vielleicht habe ich einfach ein besseres Modell erwischt oder aber die Erwartungen manch anderer Rezensenten bezüglich der Auswirkungen eines komplett abgedunkelten ND3-1000 sind einfach zu hoch. Natürlich sieht man optische Einflüsse, wenn man den ND-Filter auf ND1000 stellt. Nicht ohne Grund gibt es wesentlich hochpreisigere ND-Filter, die dann aber gerade mal den Bereich ND2-ND32 abdecken. Die eierlegende Wollmilchsau sucht jeder von uns, gibt es aber de facto nicht. Die Nano X-Serie gefällt mir super gut. Ich besitze bereits mehrere Filter der Serie und bin absolut zufrieden. Zu dem aufgerufenen Preis kann man einfach nicht meckern und ich persönlich finde die Auswirkungen bei ND1000 auch tragbar. Wenn ich besonders hochqualitative Fotos aufnehmen möchte, beispielsweise mit Langzeitbelichtung, dann verwende ich sowieso einen festen ND1000 Filter. Bin ich jedoch unterwegs und möchte auf verschiedene Situationen vorbereitet sein, nehme ich den ND3-ND1000 mit. Der Filter ist super verarbeitet, das merkt man schon an der Haptik, wenn man diesen in die Hand nimmt. Diese Verarbeitung bin ich von K&F Concept auch gewöhnt, denn auch mein Stativ, meine Objektivadapter und meine anderen Filter sind entsprechend gut verarbeitet. Von meiner Seite aus kann ich eine klare Kaufempfehlung aussprechen, wenn ihr mit den richtigen Erwartungen an solch einen Filter unterwegs seid.

Kullanılamaz bir filtre. İnanılmaz kötü bir X pattern sorunu var. Ne olduğuna internetten bakın ve almayın.

Pluspunkt für das Etui!!!

Der Filter wirkt 6/7 Stops statt der angegebenen 10 und die Bilder sind nicht immer gleichmässig belichtet. Bei höheren Werten kommt ein Kreuzmuster dazu. Als ich den Filter retourniert und mir ein ND 10 gekauft habe, wurde ich vom K&F Kundendienst kontaktiert und mir wurde ein ND 7 als Wiedergutmachung geschenkt. Der Kundendienst war sehr gut, die drei Sterne sind für das Produkt an sich.

Wirklich guter Filter zu einem passenden Preis! Eine Übersicht auf der Website oder Amazon wäre noch super um die ganzen Filter Typen zu unterscheiden!
