How to shoot this effect? Sony's nex5r is a novice and asks for advice because the border is round or the photo feels a bit like a mirror.

Judging from this picture, it should be that this camera uses a fisheye lens-but judging from the girl's gesture, it should be a self-portrait. Judging from the road next to it, it should not be taken from the window, so I don't know what this round object around me is ... Judging from the girl's self-portrait with such a relaxed gesture, it should be a card machine with a fisheye effect filter.

If the NEX-5R is built-in, it has no fisheye effect filter. You can only buy fisheye lenses with e-slots or change them. A similar effect can be achieved later, but it is not necessarily perfect ~
