I just ordered my D4 from B and H. It is suppose to arrive on Wednesday and really looking forward to it so much I wanted to post a message in the D4 forum. I have been looking around the D4 forum for awhile and reading all the comments. I have a wedding coming up soon and looking forward to using the low light qualities of the camera. I currently have a D800E and love it, but needed a second body if I am going to do weddings.
Gotta figure out my first photo, will probably be the cat. Since she is always looking to model and my family is out of town.
Yes the d4 will be a great wedding ceremony tool for shooting images. It of course will be your main camera ha ha!!! I think you will be impressed with the d4's performance in just about any kind of photography. It will just get out of your way and let you concentrate of the subject. One heck of a camera.
