Magnetic Quick Swap Filter Protection

The Freewell 112mm back cap protects the rear element of compatible magnetic quick swap filters from scratches, dust and accidental damage during storage and transport. It is designed for photographers who use the Freewell 112mm filter system and want to keep their glass in pristine condition when filters are not mounted on the lens.

Secure Rear Coverage

The cap attaches directly to the back of the filter using the magnetic quick swap interface, providing a precise fit that stays in place inside a camera bag. This dedicated rear protection means the filter’s rear glass remains clean and ready for immediate use without needing a full storage case for short moves.

Verify Filter System Compatibility

Confirm that your filters are the Freewell 112mm magnetic quick swap type before ordering, as the cap is sized specifically for that system. Buyers using other filter diameters, thread-on filters or different magnetic ecosystems will find this cap does not fit their equipment.

Questions about this item

Will the 112mm magnetic mount on the back cap wear out or need replacement over time?

The magnetic quick-swap mount is built into the cap and designed for long-term use; there is no separate component to service or replace.

What limits how long I can leave this 112mm back cap on the filter during extended shoots?

There is no usage-time limit; the cap simply shields the filter from dust and scratches whenever it is attached.

Does the 112mm back cap trap heat or add weight when left on the filter all day?

The lightweight cap adds negligible mass and does not enclose the lens optics, so it does not affect heat buildup during all-day use.
