I have this simple circuit to control the camera shutter and focus. R1 & R2 are 270 Ohm. It works fine with my Canon dSLR camera but not with the Nikon D7100. On the Nikon only the focus works, the shutter does not. Any ideas how to make it work with both cams?

Camera trigger circuit works with Canon but not with Nikon cameras

The one I used was a TIL 119 but that was a long time ago and it is now obsolete.
