Magnetic UV Filter Pro

The included Magnetic Adapter Ring threads onto your lens once. Then align the filter's grip tabs with the gaps in the ring and twist to lock. Once locked, the filter rotates freely and won't detach until it's turned back to the original alignment. 

No. Magnetic Pro Filters aren't compatible with lens hoods, Magnetic Plus Filters or Magnetic Plus Adapter Rings. 

Yes. Clip-on or side-pinch lens caps sized to the filter's thread diameter work as a cover.

No. Magnetic Pro Filters are not compatible with Urth's Threaded Step Up Ring Filter Adapter or Magnetic Step Up Ring Filter Adapter, which is designed to be used with the Magnetic Plus Filter system. 

Not always. Urth Magnetic Pro Filters have a larger outer diameter than other Urth Filters, particularly the Variable ND Pro with its wider, stepped front, which can catch the lens as it extends or retracts. Retractable lenses, such as the Fujifilm XF 23mm f/2.8 or the Leica D-Lux 8, can also be sensitive to added weight, so a filter may add resistance to the movement even when nothing is in the way.

No. It's built on AERO-C10™ ionically tempered glass, which is up to 600% stronger and 200% more scratch-resistant than standard filter glass. At 99.28% light transmission and under 0.15% reflectance, it doesn't require any exposure adjustment and won't degrade image quality.
