The 72-112mm Magnetic Step-Up Ring from Freewell allows you to screw threaded filters onto compatible lenses or magnetically adapt Freewell magnetic filters.

Filters that have 112mm rear threads can be screwed onto lenses featuring 72mm front threads. Alternatively, for magnetic attachment, first screw this adapter onto a lens that has 72mm front threads, and then magnetically attach Freewell's 112mm magnetic filters onto the front of this adapter ring.

Q: 10. Any idea if it would work with a Chimera medium softbox?

A: The Impact Fabric Grid for Large Rectangular Luxbanx (36 x 48 ) is larger than what is required by the Chimera Medium Softbox. It will fit, but it hangs too loosely to work properly. You would either have to personally modify the Impact Fabric Grid for Large Rectangular Luxbanx (36 x 48 ), or you would have to purchase the correct grid from Chimera.
