You can use a Nikon cable release that has a large threaded end that screws over the shutter button, like the old Leica shutter buttons were. Or you can buy a small adapter that screws on any standard cable release that then screws onto the Nikon shutter release. These shouldn't be too hard to find, as they were very common at one time. Hope this helps. I have a couple of Nikon F2s and refuse to get rid of them, as they are great dependable cameras.
