Steve Perry of Backcountry Gallery has posted a video discussing the pros and cons between using a cropped sensor or a full frame camera with a teleconverter. Whilst he focuses on doing so with long lenses, to some extent the same issue face us with wide angle lenses underwater.

He has also posted discussing the options of either using a TC or cropping the image in post.
