Haida has announced a new 2-in-1 filter that provides both a variable circular polarizer and a variable neutral density filter in a single device that allows each to be controlled independently.
Haida has recently introduced an inexpensive USB-powered Anti-Fog Velcro belt that wraps around the exterior of a lens and keeps it warm, therefore preventing it from fogging as the temperature dips.
The Chinese lens filter brand Haida has announced its new NanoPro Soft Diffusion Filters. The lens filters are designed specifically for capturing soft photos of the starry night sky.
Chinese accessory company Haida Photo has released a 150-millimeter magnetic filter holder for the Sony FE 12-24mm f/2.8 GM lens that provides quick and easy release of filters and does not require the lens to be removed from the camera body to affix and use.
