Wide angle is more challenging, but the 10-17 focuses so close that with a small dome you can shoot WA macro. Not really macro because even on top of the subject, it looks small (and I mean touching the dome), but a close-up of a small to medium subject with a wide background. The challenge is strobe placement and lighting both the subject and the background.
In this shot, the squids were probably an inch from the port.
In this crop, they may have been touching it.
