I don't know what an intruder release is, so I guess it doesn't include it. It is the size of a thumb drive and fits in my pocket. Amazon's knock off is better than Nikon's Nikon ML-L3 Wireless Remote Control for $15.00(at least the one I bought which stopped working after I dropped it once). I use it for landscape photography with mirror lock-up. It allows me to trigger the shutter without touching the camera. Fast multiple shots for HDR. However, it appears it does not work on cameras with a ten pin front connector. If anyone can explain why Nikon cannot have this feature on a pro camera, I'd really appreciate it.
