I am going to be shooting a wedding next week and I have kind of strange question. I have a new D800E and also a D3s for shooting. Which camera should I use. Which is the better camera for weddings. The wedding is taking place around 07:00 pm centeral time. Light should not be an Issue I don't think.
I've had both for about 9 months now, and still prefer the D3s for weddings. Except for possibly formals, you shooting will be handheld adn you may find unfavorable lighting conditions. The D3s is far more forgiving at low shutter speeds and higher ISOs. The vertical grip is helpful. Not to mention the issues related to the larger files.
Since teh D800e is new to you, you might want to get more time with it under your belt before going into a critical shooting situation with it.
Unless you are going to need prints over 16x24, I think the D3s will meet your needs quite well. Take the D800e for backup.
