Nikon Infrared remote control ML-2

It is ML-3. ML-L3 or ML-2 does not work with your cameras.

I use Radio trigger from Amazon, that works well with D200 and D700, perhaps up to 100 meters as it says - I have not tried that far, and is inexpensive.
I have confirmation of purchase, but I am sure you will find it on Amazon. There are 2 similar systems, and mine is the less expensive.

FWIW i had an ML-L3 for some previous models of Nikon bodies and I found it hard to use because of the narrow angle of acceptance. I bought a much cheaper radio unit from Phottix and it's head and shoulders above the Nikon unit.

I recently got an ML-2 for my F4S and I can't get it to seem to trip the shutter even with new batteries. Any suggestions?
