If you want to minimize those distortions, choose longer FL's or do not allow people near the borders. Another option is to use software correcting "volume anamorphic distortions" like DXO's ViewPoint. See this, for example. I use it often and the effect is very nice.

To JACS, I am guessing the example you linked to is a kind of barrel distortion? Am I right in saying it is inherent in most wide angle lenses?

No, it is natural "distortion" most visible with wide lenses near the border. Barrel distortion would actually make it look better!

Line up three bottles, shoot them with a wide lens filling the frame, and even if the lens is perfectly rectilinear, the bottles near the edges will look visibly fatter. Replace the bottles with a picture of three bottles, and they will look the same!

Thank you J A C S. By "natural distortion", do you mean something other than barrel distortion and perspective distortion?

It is usually referred to as perspective distortion.

If I use a EF 35mm IS USM on a 70D, do you think I'd see the "natural distortion"s near the borders? Or do you think the smaller sensor would've cropped out the distorted parts?

You will see less, like 50mm on FF. But if you get too close and your object is too close to the borders, you will still see it.

BTW, I am not affiliated with DXO in any way but their View Point can do wonders, you should try it.
