This was needed for the 900’s because there is no way to fit a remote
release cable to the camera and for some stupid reason Nikon designed
the macro function and timer on the same control.
I have the 990 and even though the macro and timer on on the same
control you can use both of them. You may choose from 3 seconds or
10, and get great macro photos. So far I’ve never used the flash, my
pieces are so reflective I can’t imagine I wouldn’t get intense glare.
Contact me if you have any questions.
