The SA-17 Bowens Mount to SA-P Projection Lens allows use of the Godox SA-P Projection Attachment with many Godox flash units or with any LED that has the popular Bowens front accessory mount.
Combine with the SA-P Projection Lens and now you can create focused circles of light with sharp, clean edges. Or choose to defocus and get a nice soft circle of light. Add in one of the slip in cookies with a cookie holder (sold separately) and you can create a number of other patterns on your background or subject. It's a great tool for taking a blah shot into the awesome range.
