DON’T PANIC: Here’s how to get unstuck!
As a longtime pro, I’m glad to have found this capable adapter. On the downside, this otherwise excellent model comes with zero instructions whatsoever. That’s dumb especially when it is certain to stay stuck to your lens. Have no fear. A competitor, Fotodiox has a great video that shows you where the little tab is buried inside the adapter. Find the video first. Then you will learn how to press down the tiny tab, and all will be golden again!

Otherwise, it’s well priced and great for manually changing f-stops with the included white lever. Also, it’s well made yet the K&F folks need to invest a bit in necessary instructions, pronto!
