That's the 10-17. If you really want to do what I call contextual portraits (as opposed to selfies) with K-S2, the fisheye or the 15mm are the best choices because the wider perspective gives you more of the actual context. The kit lens, or any lens that starts around 28mm eq., can work, but the stand-off is not as great and there's more of you in the picture than the background. You also get into depth of field issues where either you or the background isn't in sufficiently good focus. With the screen flipped out in Live View, you can set CDAF to face detection and get yourself in focus, and the 15mm or the fish handles the background pretty well. Or you can go the other way around with distant focus and let yourself be a little out. Even wide open, DOF on the fish is adequate at arm's length. The K-S2's rear shutter button also kills any need for a selfie stick, which I would never use in the first place but certainly not in an airport. I have no interest in talking to a security guard. It's a brilliant feature that other makers are no doubt going to copy.

A-HDR is jpeg only. You can save the median exposure to RAW as normally done with the exposure compensation button before taking another shot or turning the camera off. A-HDR is programmed to use the widest possible aperture, however, so that is what you will get. If you want something stopped down, you'll have to take another shot.
