Who uses the K&F Concept ND Filter?

“I also got a ND filter, which I've never had before. I use it as a tool to compensate my cheap lenses not having constant aperture.”

“This is a really cheap ND filter. I think I got this one for about $35 on Amazon. It is a two to five stop ND filter. K&F Concept, I do believe they are seen as the budget brand, but I bought this like 5 years ago and I still use it to this day.”
