What kind of camera do I use to shoot wedding

I use a Nikon D4. This is one of the toughest camera's I have ever used and it always comes through for me in the toughest situations! I've had wedding ceremonies that dimmed the lights at the last second and I was able to take this camera from 2000 ISO to 12,800 ISO without hesitation, knowing it could handle the extreme low light of the ceremony! Here is a picture of the camera below... it's also the reason that I don't have to go to the gym! Lifting this all day during a wedding is like doing bicep curls for 9 hours with one hand ;) 

My Nikon D4 is one of the best camera's I've ever used and one of the main reasons I'm able to shoot your ceremony in extreme low light situations ;)

Here are a few pictures I recently took with this camera. Keep in mind, that it takes more than just a good camera to get awesome pictures, but there aren't many cameras that give you the opportunity to get some of these shots.

As the ceremony took place, the light quickly vanished. A few shots after this one, I had to switch to an off camera flash, because it got way to dark. Not even my camera could handle it after a certain point.

This is one of those ceremonies where it gets dark really fast and the only thing lighting this are a couple dimly lit over head lights.

 It started raining outside and the backup plan was this dark barn that was only lit by these over head stringed lights. I had to make a decision before they walked down the aisle on wether or not to use flash. Because I trust the Nikon D4 so much, I went with natural light and it turned out amazing!
