Ok, so I am new to photography. I'm looking to invest in a long term durable dslr camera. I heard d7000 is the best in the market right now, but rumors says the d7100 is bound to release. Cost can be a bit daunting, but I don't mind spending a few extra bucks if you give me a good reason to select one over the other. Many would argue spend little money on the body & more money on the lenses. I don't really understand this notion because if that were the case, why do they make some cameras more expensive than others? After all, they all have similar functions & take similar shots, etc.
What are the essentials in a camera? If you could explain Low noise at high ISO, Wide dynamic range, High true resolution,Many focus points,Large sensor, built in flash, etc that'll be great.
