以及這篇文章, 作者說: "The SG-3IR is cheap (under $15), well made, and fully up to Nikon standards. Functionally, it's no better than taping exposed color negative film in front of your flash, but it's a lot more professional looking, and it leaves no tape residue. If you're using a camera with a built-in pop-up flash, it's a lightweight and cheap way to trigger studio lights cordlessly."
