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

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。
