Just received my NN3MKII. I have an Olympus e-510 with 12-60mm lens on it. I was able to do the set up effectively with my Manfrotto 323 Quick release plates attached directly to the lower and upper rails. I'm now able to snap the rails onto my tripod and the camera onto the rails with quick releases.
The only problem I'm having is vertical rotation. The camera runs into the lower rail with only 30 degrees rotation upward (toward zenith). Has anyone used this camera and lens combo with the NN3?
