Neither (there's a small border crop for neatness, nothing major) - I only have a compact point and shoot so dof is provided by the small sensor (so yeah, it's a crop effectively, but not by me ). I can just about get narrow dof in a few controlled situations, but getting enough dof is rarely a problem.
To put it in perspective, that was f/4 which is around the sharpest point for the camera, focal length 5.8mm. I could have gone to f/2.8 for less dof but it's not as sharp there, stepping back and zooming in further would have been a better way of doing it, but it was only a quick shot and I know the rough flash compensation I need at that distance.
Thanks for the comment
