Freewell Magnetic Back Cap (77mm)

The 77mm Magnetic Back Cap is a filter cap compatible with the Freewell magnetic quick swap filters. Made of metal, it magnetically attaches to a 77mm quick swap filter to protect it in transport. The cap allows you to protect the filter when you don't want to carry the filter in a storage case. It's useful for times when you don't want to carry a storage case with all your filters but rather just want to take the filter(s) you need for the shoot.
