It came with an 18-55mm lens on it. It's a good little lens and it took some wonderful pictures for me, but I was wanting something a little bigger and better so I had decided I would use whatever money I got for my Birthday and Christmas to get me a new lens, or at least go towards getting a new lens.
On my lens there is a switch that allows you to switch from AF (Auto Focus) to MF (Manual Focus) I don't take it off Auto much but every once in a while I can't get it to focus in on what I want so I will place it on Manual and focus it in my self.
The little lightning bolt button is what you push when you would like to use the flash in any of the setting I have just discussed except the Fully Auto setting.
So here's my camera and a little bit of how I use it. If you have any questions feel free to ask and I will do my best to answer them.
