Kase Magnetic Circular Step Up Ring - 49mm-72mm

This ring is designed for Kase's magnetic filter system. While a standard 72mm filter might physically screw onto the 72mm end, the magnetic attachment feature will not function, and the fit may not be optimal.

It will screw onto any lens with a 49mm filter thread. However, compatibility with lens hoods or other accessories attached to the lens may vary.

Use a soft, dry microfiber cloth. Avoid using any liquid cleaners, as they can affect the magnetic connection and potentially damage the finish.

The main advantage is the magnetic attachment for filters, which allows for much faster filter changes compared to screwing them on and off.

Yes, you can stack multiple Kase magnetic filters. This ring is designed to help minimize vignetting when filters are stacked.

Yes, the quick magnetic attachment makes it ideal for video recording where rapid adjustments to lighting conditions are often needed.

Verify the lens has a 49mm filter thread. Ensure there are no obstructions or damage to the lens threads or the ring's internal threads.

Ensure both the ring's magnetic surface and the filter's magnetic edge are clean and free from dust or debris. Check that you are using a 72mm Kase magnetic filter.

While designed to reduce vignetting, extreme wide-angle lenses or stacking too many filters can still cause it. Try using fewer filters or ensure the ring is properly seated on the lens.

Grip the ring firmly but gently and unscrew it in a counter-clockwise direction. If stuck, try a rubber grip pad for better traction.
