CamKix Cinematic Filter Pack compatible with GoPro HERO 4 and 3+ Includes 4 Neutral Density Filters (ND2/ND4/ND8/ND16), a UV Filter and a Cleaning Cloth. Enhanced Footage at Lower Shutter Speeds

I have been looking for a Neutral Density filter for my GoPro Hero 4 Black to avoid propeller interference when use it whilst flying single-engine light aircraft. I was rather disheartened by the price of many of the offerings on the market and then I stumbled upon this item, which is not only excellent value for money, but very easy to use - just pop the desired lens directly onto the GoPro lens and Bob's your uncle. You also get a total of 5 ND filters plus a sixth which may be UV or just a lens protector - I haven't yet worked out which. Overall an outstanding product that does the job at a fraction of the price of the competition.

Only used these filters a couple of times but I've no complaints. CamKix bring us another quality product at a very reasonable price. Although, @CamKix, I'd have liked it more if the filters came with a storage case...not sure how I can safely carry these around?

Great product for the price, bought them to remove the horrible wash of the propeller when filming on general aviation aircraft and they do the job perfectly, you need to master them based on the light when filming. I am yet to try them for other type of filming except flying however I am very pleased as despite the price they do not affect the quality of the video (I always do post processing with Premiere anyway!).

Good range of four ND filters and one UV filter. These are a push-fit on the standard Hero 4 lens, so can only be used with a skeleton type frame. They came very well packed in a foam filled cardboard box, and the only suggestion I have is that instead of a cardboard box a Tupperware-style plastic container would be better for permanent storage. All in all a very useful piece of kit.

Awesome! Work great !

Absolute rubbish. The ND16 has serious purple vignetting which renders it totally useless. Not bothered trying the others, but if you value your videography (which if you are buying these I'm sure you do) I'd reconsider. Check out the purple grass in my screenshot below. This was after 4 tests to make sure it was sat on the lens correctly etc.

ND8 Removes propeller blur exactly as expected. Nice to have the other values and the UV filter. Good value, works well.

Fits great and good product / value for money. Happy customer .

I am writing this review because I am completely satisfied with the product. I am using these on a GoPro Hero 4 and on a Campark 4k on my aerial cinematography drone. I had to do some small modifications to the Campark action camera to enable these filters to fit. These filters do what they what ND filters should do with the proper camera and exposure settings. They help to produce the desired motion blur, and have totally removed all minor jello effect that I was getting every now and then. The aerial footage that I am taking with these filters looks crystal clear at 4k@30, and I am very happy with this product. My drone is carefully tuned for aerial cinematography, and I am using the Walkera G-3DH high precision 3-axix gimbal, which I have carefully tuned as well.

correcte

Der ND Filter ist bei einer GoPro immer mit Bedacht zu verwenden, weil die Kamera Licht selbst regelt.Durch den Filter bekommt man den bei schnellen Bewegungen einen gewissen Blur.Meistens verwende ich die Abdeckungen mit dem leichtesten ND Filter, die höheren sind mehr bei sehr starkem Lichteinfluss brauchbar.

Envio super rápido y muy bien presentado en caja muy bien protegida. Por su precio hacen su funcion razonablemente aunque hay que vigilar si se orientan directamente al sol ya que reflejan mucho y cambian el color. No son muy recomendables si queremos una imagen minimamente profesional.

Ho acquistato questo set di filtri perchè avevo la necessità di migliorare le mie riprese in movimento in ambienti con una luce molto forte.Io utilizzo principalmente i filtri per riprese in moto per evitare una sovra esposizione di luce oltre hai filtri nd vi è anche un filtro uv.i filtri arriveranno all'interno di una pratica confezione .All'interno della confezione troverete :-Un panno per pulire i filtri.-Un filtro ND 2.-Un filtro ND 4-Un filtro ND 8-Un filtro ND 16-Un filtro UV.La confezione è molto comoda per tenere i filtri, i filtri sono tutti protetti da una pellicola protettiva per evitare che si graffino, i filtri vanno montati utilizzando un frame e vanno incastrati direttamente sulla lente della gopro, avendo cosi anche una funzione protettiva per la lente che evita cosi di rovinarsi, graffiarsi, sporcarsi ecc .I filtri rimangono molto saldi sulla lente e dopo un utilizzo anche a velocità sostenuti rimangono perfettamente in posizione, il loro lavoro lo fanno egregiamente bisogna solo scegliere quale tra i filtri disponibili sia il più adatto ad ogni situazione.Provandoli sono rimasto pienamente soddisfatto dal prodotto e ne sono rimasto sorpreso perchè anche se non sono un prodotto molto costoso sono veramente di ottima fattura.Consiglio questo set di filtri a tutti quelli che si vogliono approcciare al mondo della fotografica e delle actioncam e che vogliono migliorare la loro qualità di ripresa senza spendere troppo. Sono veramente un ottimo prodotto
