Despite the mention in the description, saying that is not good for wide angle lenses, I purchased it for a Viltrox 16mm f:1,8, EF mount. The results are outstanding across the entire range of the filter. No X cross, no vigneting. At least for this specific lens, the filter is perfect. Is true, the size of the barell is twice the size of the front lens, leaving enough room for any kind of filter.

I was given this filter by K&F concept to review, but this is my honest review based on using it for a few shoots of both photography and videography. The filter comes in a really nice plastic protective case, also included is a cleaning cloth in a pouch. The cardboard box itself is sturdy with a magnetic opening.I asked for the 77mm filter to fit my biggest lens and got some step up rings so I can use this on all my lenses and by stepping up you wont get vignetting. The filter itself feels very good quality and well built, the exposure adjustment ring allows you to choose between five stops, it feels like a fluid video head and will not move on its own.I didn't witness any colour shift, or any photo or video issues using this filter, also there was no sign of the black X some filters show when the two optics cross at their maximum point.I would definitely recommend this variable ND filter, its at a very good price point and by using step up ring for around £10 you can have this one filter work on all your lenses, that is a lot cheaper than a few sets of ND filters when your lenses have different sized filter threads.Using this on video at either 25 or 30 fps using shutter speeds of 50/1 or 60/1 this filter easily cut down the light to stop my footage being over exposed.I have added a review on YouTube and video demo, you can find this by searching youtube for this product description.

Ich hatte monatelang nach einem guten ND-Filter gesucht; indem ich Landschaftsfoto machte, brauchte ich einen so genauen Nd-Filter wie möglich, der keinen Wert meines Fotos änderte. Nachdem ich andere berühmte Marken (zum doppelten Preis dieser) voller Mängel ausprobiert hatte, fand ich mit diesem Modell endlich die perfekte Nd-Variable! Tadellose Qualität, wirklich ein großartiges Produkt! Sehr zu empfehlen!!!

Great filter for video with all the ND steps you really need.

This adapter made a good physical connection between my lenses. Good build quality.

Well made adaptor for fitting my lenses to Sony E fit camera.

Das ist das beste Nd filter
