Stop hunting for threaded plastic caps that crack, fall off or refuse to spin in winter gloves. Kase re-imagines the humble lens cap as a magnetic, multi-function tool: press to attach, pull to remove, and—when inspiration strikes—swap the glass core for an ND or CPL filter without ever taking the cap off the lens. How it works Stick the supplied magnetic adapter ring onto your lens filter thread (ultra-thin 0.5 mm, leaves no vignetting). The cap self-centers and locks with 1.2 kg holding force—strong enough to survive a 1 m drop, yet releases with a simple thumb-forefinger pinch. Traveling light? Replace the clear protector disc with any 34 mm Kase magnetic filter sheet and you’ve turned your lens cap into a 3-stop ND, polarizer or anti-light-pollution filter in under 5 seconds. Built for professionals CNC-machined 6061-T6 aluminum, hard-anodized matte black for zero reflection. 28-layer nano-coated optical glass, 99.5 % transmission, oil & water repellent. Works from -30 °C to +80 °C; salt-water safe for coastal shooters. Compatible with Kase Wolverine magnetic filters, square holders, and original lens hoods simultaneously.
