I imagine that if you're shooting jpegs then the in-camera DA lens distortion correction will fix the it. If you're using RAW then you'll have to do that later.

However, it is easily fixed either way.

Having read up on it a bit, I don't think the lens designer intended it to be fixed. Almost invariably, when I "correct" the 21mm lens in my raw converter (Capture One), I immediately un-correct it because rectilinear projection (a form of distortion that some insist is "correct") provides an especially unnatural look. It wasn't what you saw - as your eyes are most-certainly not capable of rectilinear projection (we see in a 3D plane essentially).

If you want to use a lens for architecture or shooting resolution charts, then by all means make rectilinear a key criteria. Certainly wouldn't want to shoot a group of people with it. In this shot, the fellow on the right - who is an avid photographer - almost certainly saying to himself "you're going to make me look really stupid if you correct that image" (I didn't): Sara & James - James Robins - Powered by Phanfare
