I'm looking to get my first camera finally. I want to get a nikon, but don't know which is the best to buy. I don't particularly need the ability to shoot HD video at all, but it would be a nice addition if it was worthwhile getting one of the Nikons that can do it anyway. I will be shooting an assortment of things, and would rather get one in a twin lens kit (as that will save money in the long term) Also, what's the big deal about cameras that have the auto lense focus, and ones you have to do manually? All information is appreciated, thanks.
