K&F Concept 77mm ND Filter,K&F Concept 77mm Ultra Slim ND2-ND400 Fader Variable Neutral Density Adjustable Lens Filter Ultra Slim ND Filter Optical Glass

So important! It immediately made my visuals look good under bright sun.

solid build quality not that expensive and not cheap either..

Smooth and dims well. Didn’t notice an x mark. No thread for lens cap which is a deal breaker for me, will be returning.

لا غنى عنه للكاميرات الصغيرة وخاصة M50 في التصوير الخارجي

I like the product very very much. Premium build and quality. Pictures are clear as they should be, without any refractions. Only downside is, i bought this filter for my Tamron 35-150mm lens, but when i have the filter attached, i cant attach the lens hood as it wont fit! so you have to use your lens without a hood. If thats a compromise you cant live with, then dont get this filter as thats the only downside it has. The lens cap also barely fits/attaches securely, as the thread is vey thin.

Terrible filter creating vignettes. I didn't manage to check it in time and return the money. Please return the money

Good but need to remove lenses hud cap

I bought this filter with lots of hopes and when i used it it is showing cross or X in the middle when i rotate it to max. Now i have to buy fixed nd filter set

The quality is great and it's exactly what I need for my zv-e10 kit lens.

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on. But after-service support was pretty helpful in telling me this

Ottimo filtro a ND variabile io l'ho montato su un obiettivo Sigma per Lumix e per le interviste è perfetto non distorte assolutamente l'immagine

tres belle piece bon produit

初めて使うのには良い商品かも。 場所に合わせて調整出来るのも良いですね。 もっと早く買っとけば良かった。調整が簡単なのが良いです。
