Even with a rubber coating, they use magnets and as such could pick up small amounts of ferrous material that would cling to the rubber surface so should be checked before mounting to a lens. Anything coming in to contact with a lens element should be done with care. Having said that, the magnets are at a position on the lens element that should not be in view of the recorded image, so if care is taken mounting a filter, then scratches should only occur outside of the field of view of the sensor. I have used both Freewell and SkyReat filters for a while now with no signs of front lens element scratches. My main concern is with fingerprints and dust with handling more than scratches. |
