PolarPro Plug-in filter Helix 2/5 Stop VND McKinnon Edition

A completely seamless filter experience - never unscrew a filter again. The new MagLock system features magnets that connect the filter and the threaded base, while a quarter turn secures the system in place. No vignetting up to 17 mm with one filter (16 mm with Canon/Nikon) and 19 mm with two filters stacked. The rubber frame insert provides more grip compared to aluminum filter frames. The filter frames and thread bases are made of brass. Front and rear defender caps offer unmatched protection during transport and storage. Available in 67mm, 72mm, 77mm, and 82mm base plates for all your lenses. The Helix MagLock filter system is designed to eliminate the hassle of screwing on and off filters while providing a filter that securely locks in place after installation. Unlike other magnetic filter systems on the market, Helix offers an absolutely secure connection through our magnetic locking mechanism with a quarter turn, allowing for quick attachment and detachment of filters while ensuring they stay in position even in the most demanding shooting situations. These filters won't go anywhere until you remove them from your lens. With the available 67mm, 72mm, 77mm, and 82mm brass threaded bases, Helix easily covers your entire lens arsenal.
