Kase magnetic lens hoods are designed to be used with standard step-up rings only, or directly to your lens if the filter thread has the same filter size as the lens hood. Not with Kase magnetic step-up rings and adapters.
Please use provided Magnetic Hood adapter only.
Shooting with a larger Magnetic Filter adapter to avoid vignetting?
The Magnetic Lens hood allows you to stack and continue shooting with your Magnetic Circular filters and lens hood combined.
The lens hood works in the same method as your magnetic circular adapters.
Screw on to the front of your lens, clip the lens hood on, stack your filters inside.
