How can I take a selfie with this camera and what equipment will I need to purchase to accomplish this?
This camera has no rotating screen, so you cannot see the photo while taking it. You'll have to use common sense and guesswork to figure out which way to point it.
Hold it out at arms length, with the lens pointing straight at your face. Then push the button. Review the image on the screen and if the framing is off, try again.
The camera is small enough that you might be able to use a selfie stick and the self timer feature of the camera.
If you want to see the screen while framing the photo, then get yourself a mirror.
